Module 3: Passwords & Biometrics

What you will learn: How to keep your accounts secure without memorizing dozens of passwords. We will cover Face ID, password managers, and what those security terms actually mean in plain language.

A person using a fingerprint sensor on a smartphone to log in securely

Helen, 69, had one password for everything: her late husband's name followed by their anniversary year. She used it for her email, her bank, her iPad, Amazon, Facebook — everything. "It's easy to remember," she told her daughter.

Then one day, Helen noticed strange purchases on her Amazon account — three expensive Bluetooth speakers she had never ordered. Someone had figured out her password (it turns out her husband's name and their anniversary were both on her Facebook profile) and used it to get into her Amazon account. Because Helen used the same password everywhere, the thief also tried it on her email — and got in.

Helen spent two stressful weeks changing passwords, calling her bank, and locking down her accounts. But the experience taught her something she now shares with every friend: "One password for everything is like one key for your house, your car, and your safety deposit box. If someone copies that key, they get into everything."

Today, Helen uses Face ID and a password manager. She says managing her passwords is now easier than it was before — and far, far safer.

Security Terms in Plain Language

Before we go further, let us define some words you might hear. Think of this as your personal dictionary:

Your Security Dictionary

Password: A secret word or phrase that proves you are who you say you are. Like a key to a lock.

Biometrics: Using your body to prove your identity — your face, your fingerprint, or even your voice. "Bio" means life, and "metrics" means measurement. So biometrics means "measuring something about you."

Face ID: Apple's system that uses the front camera on your iPad or iPhone to recognise your face. It is like a security guard who knows what you look like and opens the door when they see you.

Touch ID: Apple's fingerprint reader, found on older iPads and iPhones. You press your finger on the Home button and it recognises your unique fingerprint.

Face Unlock / Fingerprint Unlock: Android's version of the same idea. Many Android phones and tablets can recognise your face or your fingerprint to unlock your device and confirm your identity.

Password Manager: A secure digital vault that remembers all your passwords for you. You only need to remember one master password — the vault remembers the rest.

Two-Factor Authentication (also called 2FA or "two-step verification"): An extra security step when you log in. After typing your password, you also need a second proof — usually a code sent to your phone. It is like a door that needs both a key and a secret knock.

Apple ID: Your personal account with Apple. It is the email address and password you use to download apps, use iCloud, and access Apple services. Think of it as your membership card for everything Apple.

Google Account: Your personal account with Google. It is the email address (usually Gmail) and password you use to download apps from the Play Store, back up your data, and access Google services. Think of it as your membership card for everything on your Android device.

💛

Confidence Check: Those terms are not so scary when they are explained properly, are they? You are building your tech vocabulary.

Biometrics: Your Face or Fingerprint Is Your Password

Modern devices can recognise you by your face or fingerprint. This is one of the most convenient and secure ways to protect your device.

Face ID on iPad and iPhone

If your iPad or iPhone is a newer model, it likely has Face ID.

How Face ID works: When you set up Face ID, your device takes a detailed map of your face using special sensors. It does not take a regular photograph — it creates a mathematical model of the shape of your face. This model is stored only on your device (it is never sent to Apple or anyone else). When you pick up your device and look at the screen, it checks: "Is this the same face?" If yes, it unlocks.

Setting Up Face ID

1 Find the Settings app on your Home screen. It looks like grey mechanical gears.
2 Tap Settings to open it.
3 Scroll down the left side and tap "Face ID & Passcode".
4 You will need to enter your current passcode (the number you type to unlock your iPad).
5 Tap "Set Up Face ID".
6 Hold your iPad at arm's length and position your face in the circle on the screen. Slowly move your head in a circle, as if you are tracing the outline of a large clock with your nose.
7 You will need to do this twice. Follow the on-screen instructions.
8 When it says "Face ID is now set up" — you are done! Your face is now your password.
Good to Know

Face ID works with glasses on or off, and it adapts as your appearance changes gradually over time. It does not work with a face covering, so you may need your passcode when wearing a mask. Face ID will also not let someone unlock your device while you are sleeping — your eyes need to be open and looking at the screen.

Fingerprint and Face Unlock on Android

Most Android phones and tablets come with a fingerprint reader, and many newer models also offer face unlock. The fingerprint reader is usually found on the back of the device, on the side (built into the power button), or under the screen itself. Setting it up is straightforward and takes just a couple of minutes.

Setting Up Fingerprint Unlock on Android

1 Open the Settings app (the gear icon on your Home screen or in the App Drawer).
2 Scroll down and tap "Security" or "Biometrics and Security" (the exact name varies slightly between Samsung, Google Pixel, and other brands).
3 Tap "Fingerprint" or "Fingerprints".
4 You will be asked to enter your current PIN, pattern, or password (the code you normally use to unlock your device). If you do not have one set up yet, the device will ask you to create one first.
5 Tap "Add fingerprint." The device will ask you to place your finger on the fingerprint sensor.
6 Gently tap and lift your finger on the sensor repeatedly. The screen will show you how much of your fingerprint has been captured. Move your finger slightly each time to cover all the edges.
7 When the device says your fingerprint has been added — you are done! Your finger is now your password.

Setting Up Face Unlock on Android

1 Open Settings and go to "Security" or "Biometrics and Security."
2 Tap "Face recognition" or "Face Unlock."
3 Enter your PIN, pattern, or password when prompted.
4 Hold your device at arm's length and position your face inside the circle on the screen. Hold still while the camera scans your face.
5 When the device confirms your face has been registered, you are all set.
Good to Know

Android fingerprint unlock is very reliable and works even if your hands are slightly damp. Face unlock on Android is convenient, but on most devices it is slightly less secure than fingerprint — some models can be unlocked with a good photograph. For best security, use fingerprint as your primary method and face unlock as a backup. You can have both set up at the same time.

Windows Hello: PIN, Face, and Fingerprint on Windows

Windows computers have a built-in sign-in system called Windows Hello. It lets you sign in with a PIN, your face (on computers with the right camera), or a fingerprint (on computers with a fingerprint reader). A Windows Hello PIN is especially useful — it is different from your Microsoft account password, and it only works on that specific computer.

Setting Up a Windows Hello PIN

1 Click the Start button (Windows logo, bottom left) and then click the Settings gear icon.
2 Click "Accounts" from the list on the left side.
3 Click "Sign-in options."
4 Under "Windows Hello PIN," click "Add" or "Set up."
5 You will be asked to confirm your Microsoft account password first, then choose a PIN of at least 4 digits. Write it down and keep it in a safe place.
6 Once set up, you will type this shorter PIN to sign in instead of your long password. Much easier to remember!
Good to Know

Your Windows Hello PIN is tied to your specific computer — it cannot be used anywhere else. This means even if someone finds your PIN written down, they cannot use it to access your account from another device. It is safe to write your PIN on paper and store it securely.

💪

You already know the most important security terms. That knowledge is your foundation.

Most people never learn what these words actually mean — you are already ahead.

Creating Strong Passwords

For accounts where you still need a typed password, here is how to make a good one:

Weak Passwords (Do Not Use These)

123456, password, your name, your pet's name, your birthday, your anniversary, your address, "qwerty," or any single word found in the dictionary.

Watch Out

Using the same password for multiple accounts is like using the same key for your house, your car, and your safety deposit box. If a thief copies that one key, they get into everything.

A strong password is like a strong lock — it has multiple parts that work together. The best way to create one is the passphrase method:

The Passphrase Method

Instead of a single word, use a short phrase of random words. For example:

Purple-Teacup-Bridge-44

This is much harder for a computer to guess than "MyName1954" but much easier for you to remember. You can picture a purple teacup sitting on a bridge with the number 44 on it. The sillier the image, the easier it is to remember.

More examples: Garden-Rabbit-Snow-17 or Kitchen-River-Maple-82

The key rules for passwords:

💛

Confidence Check: You do not need to be a computer expert to have strong passwords. A silly phrase you can picture in your mind is all you need.

Tip

Write your master password on paper and keep it in a locked drawer or a safe — never on a sticky note attached to your device. A paper backup in a secure location is perfectly fine.

Password Managers: Your Digital Vault

"But how am I supposed to remember a different password for every account?" Great question. The answer is: you are not. A password manager does it for you.

Your iPad comes with a built-in password manager called iCloud Keychain. Here is what it does:

  • When you create a new account on a website, your iPad offers to save the password for you.
  • When you return to that website, your iPad fills in the password automatically — you do not need to type it.
  • It can suggest strong passwords when you are creating a new account.
  • It warns you if one of your saved passwords has been found in a data breach.
  • All of this is protected by your Face ID or passcode — no one else can see your passwords.

Making Sure iCloud Keychain Is Turned On

1 Open Settings (the grey gears icon).
2 Tap your name at the very top of the Settings screen (it shows your name and "Apple ID, iCloud, Media & Purchases").
3 Tap "iCloud".
4 Tap "Passwords and Keychain".
5 Make sure the switch next to "Sync this iPad" is turned on (green). If it is already green, you are all set.

Viewing Your Saved Passwords

1 Open Settings.
2 Scroll down and tap "Passwords".
3 Use Face ID or enter your passcode to see your saved passwords.
4 You will see a list of websites and the passwords saved for each one. Tap any entry to see the details.

Your Android device comes with a built-in password manager called Google Password Manager. It works through your Google account and your Chrome browser. Here is what it does:

  • When you create a new account on a website in Chrome, your device offers to save the password for you.
  • When you return to that website, your device fills in the password automatically — you do not need to type it.
  • It can suggest strong passwords when you are creating a new account.
  • It warns you if one of your saved passwords has been found in a data breach (called a "Password Checkup").
  • All of this is protected by your screen lock (fingerprint, face unlock, or PIN) — no one else can see your passwords.

Making Sure Google Password Manager Is Turned On

1 Open the Chrome app (the colourful circle icon).
2 Tap the three dots in the top-right corner of the screen.
3 Tap "Settings".
4 Tap "Password Manager" (or "Passwords" on some versions).
5 Make sure "Offer to save passwords" is turned on (the switch should be blue). If it is already on, you are all set.

Viewing Your Saved Passwords

1 Open the Settings app on your device.
2 Tap "Passwords and accounts" or "Google" and then "Password Manager."
3 Use your fingerprint, face unlock, or PIN to confirm your identity.
4 You will see a list of websites and apps with saved passwords. Tap any entry to see the details.
Helpful Hint

You can also visit passwords.google.com in any web browser to see all your saved passwords. You will need to sign in with your Google account. This is handy if you want to review your passwords on a computer as well.

Your Windows computer comes with a built-in password manager inside Microsoft Edge (your web browser). It works very similarly to the iPad and Android versions. Here is what it does:

  • When you create a new account on a website, Edge offers to save the password for you.
  • When you return to that website, Edge fills in the password automatically — you do not need to type it.
  • It can suggest strong passwords when you are creating a new account.
  • It monitors for data breaches and alerts you if any of your saved passwords have been compromised.
  • All of this is protected by your Windows Hello PIN or computer password.

Turning On Password Saving in Microsoft Edge

1 Open Microsoft Edge (the blue wave icon on your taskbar or Start menu).
2 Click the three dots (...) in the top-right corner of the browser.
3 Click "Settings."
4 On the left side, click "Passwords" (or search "Passwords" in the search bar at the top of Settings).
5 Make sure "Offer to save passwords" is turned on (the switch should be blue/on). If it is already on, you are all set.

Viewing Your Saved Passwords in Edge

1 Open Edge, click the three dots (...), then Settings → Passwords.
2 You will see a list of all saved passwords. Click the eye icon next to any entry to see the password (you may be asked to confirm with your Windows Hello PIN).
Helpful Hint

If you prefer to use Google Chrome on your Windows computer, Chrome has its own built-in password manager that works identically. You can also visit passwords.google.com in any browser to see your Google-saved passwords. Both systems work beautifully — use whichever browser you are comfortable with.

🌟

You now understand password managers — the single most powerful tool for keeping your accounts safe.

You do not need to memorise dozens of passwords. The vault does it for you.

What About Third-Party Password Managers?

Your device's built-in password manager (iCloud Keychain, Google Password Manager, or Microsoft Edge) is free, already set up, and works perfectly for most people. However, some people prefer a separate app — especially if they use multiple types of devices (for example, an iPhone and a Windows computer).

Here are the three most trusted options if you decide you want one:

Third-Party Password Manager Comparison
App Cost Best For Ease of Use
Bitwarden Free (paid: $10/yr) Best free option — open source, widely trusted Moderate
1Password ~$36/yr Easiest to use, excellent for families, works on all devices Very easy
LastPass Free (limited) / $36/yr Long-standing service; had a security incident in 2022 — acceptable if you change your master password Easy
Our Recommendation

For most seniors: use your built-in password manager. It is free, already there, and works beautifully. If a family member suggests a third-party app and offers to help you set it up, Bitwarden (free) or 1Password (paid, easiest) are excellent choices. You do not need to rush into this — start with what is already on your device.

How to Set Up a Third-Party Password Manager

If you decide to try a third-party password manager, here is how to get started with 1Password — the easiest option for beginners. There is a 14-day free trial so you can try it before you pay a cent.

  1. Download the app. On your iPhone or iPad, open the App Store and search for "1Password." Download the app — it is free to install for the trial. On Android, find it in the Google Play Store.
  2. Create your account. Open 1Password and tap "Create Account." Enter your email address. You will receive a confirmation email — open it and tap the link to confirm.
  3. Create your Master Password. Choose ONE strong password you will remember. Three or four random words strung together work well: "Sunset-Garden-Bicycle-Maple" — long and easy to picture, but very hard to guess.
  4. Write your Master Password on paper. Write it clearly and keep it in a safe place at home — a drawer, a lockbox, or with your important documents. This is the one time paper is better than digital.
  5. Add your first password. Open a website you use often. When you see the login page, 1Password will offer to save your username and password. Tap "Save Login." Done!
  6. Next time you log in. When you return to that website, 1Password will offer to fill in your username and password automatically. Just tap "Fill" — no typing needed.
  7. Let it create new passwords. Next time you sign up for a new account, tap "Generate Password" in 1Password. It creates a strong random password and saves it. You never need to see or remember it.
Protect Your Master Password

Your Master Password is the key that unlocks every other password. Never save it digitally — not in a text file, not in an email draft, not in Notes on your phone. Write it on paper, store it at home, and do not share it with anyone except a trusted family member kept for emergencies.

If you forget your Master Password, 1Password cannot recover it — that is what makes it secure. The paper backup is your lifeline. Keep it safe.

Two-Factor Authentication: The Double Lock

Imagine your front door had two locks — a regular lock and a deadbolt. Even if someone copied your key, they still could not get in without also having the deadbolt key. That is what two-factor authentication does for your online accounts.

When you turn on two-factor authentication (let us call it "the double lock"), logging in works like this:

  1. You type your password as usual (the first lock).
  2. The website sends a short code (usually 6 numbers) to your phone or iPad (the second lock).
  3. You type that code into the website.
  4. Now the website knows it is really you — because even if someone stole your password, they would also need your phone to get the code.

Your Apple ID already uses two-factor authentication by default. When you sign in on a new device, Apple sends a code to your other devices. This is normal and it is protecting you.

The 3-Second Rule for Codes

Stop Did you request this code?
🫁 Breathe If you did not try to log in, someone else might be trying.
🔍 Verify Never share a verification code with anyone who calls or texts you. Change your password if you did not request it.

The Four Types of Two-Factor Authentication

There are a few different ways to set up your "second lock." Here they are from easiest to most advanced — you only need to pick one:

1. Text Message Code (SMS) — Easiest for Beginners

When you log in, the website sends a 6-digit code to your phone as a text message. You type the code to complete the login. Takes about 10 extra seconds. No special app required — just your mobile phone number.

Best for beginners

2. Email Code

Similar to SMS, but the code is sent to your email address instead of your phone. Good backup option if you prefer not to give out your phone number.

3. Authenticator App — More Advanced

Apps like Google Authenticator or Microsoft Authenticator generate codes every 30 seconds — even without internet connection. More secure than SMS because codes are not sent over the phone network. Requires one-time setup per account.

Best for maximum security

4. Face ID or Fingerprint + Password

Using your face or fingerprint combined with your password. If you already use Face ID on your iPhone, you are doing this for your Apple account — Apple enables it by default.

Already on your iPhone or iPad
Which Accounts Most Need the Double Lock?
  • Banking — Most Canadian banks already require it. You may be using it without realising.
  • Email (Gmail, Outlook) — Very important. Your email can be used to reset all your other passwords.
  • Government services — CRA My Account, Service Canada.
  • Facebook & Instagram — Optional but recommended.
  • Amazon — Optional; especially important if you have a saved credit card.

Start with your email and your bank. These two accounts are the most important to protect, and once they are secured, the rest follows naturally.

Turn On the Double Lock for Your Gmail Account

Gmail (Google's email service) is used by millions of Canadians. Here is how to turn on two-factor authentication so your email is protected even if someone guesses your password.

📱 On iPhone or iPad (in the Gmail app or Safari)

  1. Open the Gmail app (red and white envelope icon) and make sure you are signed in.
  2. Tap your profile photo (your initial or photo, top right corner).
  3. Tap Manage your Google Account.
  4. Tap the Security tab at the top.
  5. Scroll down to How you sign in to Google.
  6. Tap 2-Step Verification.
  7. Tap Get started and follow the steps. Google will ask you to enter your phone number so it can send you a code by text message.
  8. Enter the code Google sends you to confirm it works, then tap Turn on.
What to Expect After Turning On 2FA

The next time you sign in to Gmail on a new device or after logging out, Google will send a 6-digit code to your phone. Just type in the code and you are in. On your own phone or iPad, you usually stay signed in and will not be asked for a code every time.

🤖 On Android

  1. Open the Gmail app and tap your profile photo (top right).
  2. Tap Manage your Google Account.
  3. Tap the Security tab.
  4. Tap 2-Step Verification under "How you sign in to Google."
  5. Tap Get started. Enter your password if asked.
  6. Choose Text message as your verification method and enter your phone number.
  7. Enter the code Google sends you, then tap Turn on.

💻 On Windows, Mac, or Chromebook

  1. Open your browser and go to myaccount.google.com.
  2. Click Security in the left menu.
  3. Under "How you sign in to Google," click 2-Step Verification.
  4. Click Get started and sign in if asked.
  5. Follow the prompts to add your phone number.
  6. Enter the test code Google sends to confirm it works.
  7. Click Turn on.
The One Rule You Must Remember

Never give your 2FA code to anyone. A legitimate company will never call you and ask for your 6-digit code. If someone calls asking for your code — whether they say they are from Google, your bank, or the government — hang up immediately. That code is the key to your account, and giving it away hands them complete access.

Answering Your Questions About the Double Lock

What if I lose my phone?

When you set up 2FA, most services show you a set of backup codes — a list of one-time emergency codes. Print these or write them on paper and store them with your important documents. If you lose your phone, use a backup code to get in, then update your settings.

You can also contact the company's customer support line. They have a process for verifying your identity and restoring access — it may take a day or two, but it works.

Will I need a code every single time I log in?

No! Most services remember your own device for 30 days or longer. Once you log in successfully on your home computer or phone, you will not be asked for a code again for weeks. You mainly get a code when you log in on a new device or after a long time away from the site.

Is it really worth the extra step?

Yes — absolutely. Two-factor authentication stops over 99% of automated account hacking attempts. That 10 extra seconds once a month is a small price for knowing your bank account, email, and photos are protected. Security professionals use 2FA on every important account they own.

Do I have to use it?

Most websites make it optional — but some banks and government sites are starting to require it. Even where it is optional, enabling it for your bank and email is strongly recommended. Think of it like wearing a seatbelt: not every drive ends in an accident, but it is the right habit that protects you when it matters.

A Real Example: Logging In to Your Bank with the Double Lock

Remember the 3-Second Rule

Stop. Breathe. Think before you tap. If something feels urgent or too good to be true, that is your signal to pause.

Tip

If you receive a verification code you did not request, do not panic — but do change the password for that account as soon as possible. It means someone is trying to log in as you.

Practical Exercise: Strengthen Your Security

Let us put what you have learned into action. Work through these steps at your own pace — you do not need to do them all in one sitting.

  1. Check Face ID: Go to Settings → Face ID & Passcode and make sure Face ID is set up. If it is not, follow the walkthrough above to set it up.
  2. Check your Keychain: Go to Settings → Passwords and look at your saved passwords. Are any of them marked with a warning triangle? If so, those passwords may have been found in a data breach — consider changing them.
  3. Create a passphrase: Think of three random words and a number. Write it down on paper and store it in a safe place (like a locked drawer — never on a sticky note on your iPad).
  4. Change one password: Pick one account (perhaps an online shopping site — start with something that is not your bank) and change the password to your new passphrase.
Success looks like this: Face ID is set up and working. You have at least one strong passphrase password. You know where your saved passwords are stored on your iPad.
  1. Check your fingerprint or face unlock: Go to Settings → Security (or Biometrics and Security) and make sure at least one fingerprint is registered. If not, follow the walkthrough above to set it up.
  2. Check your saved passwords: Open Chrome, tap the three dots, then Settings → Password Manager. Look at your saved passwords. If there is a "Password Checkup" option, tap it to see if any of your passwords have been found in a data breach — consider changing those.
  3. Create a passphrase: Think of three random words and a number. Write it down on paper and store it in a safe place (like a locked drawer — never on a sticky note near your device).
  4. Change one password: Pick one account (perhaps an online shopping site — start with something that is not your bank) and change the password to your new passphrase.
Success looks like this: Fingerprint or face unlock is set up and working. You have at least one strong passphrase password. You know where your saved passwords are stored on your Android device.

Well done! You have strengthened your device's security with biometrics and better passwords. Every step you take makes your accounts safer.
