What Makes a Password Strong

Cybersecurity and Infrastructure Security Agency (CISA) explains its advice on its use strong passwords page. A strong password is long, random and unique.

How to Create a Strong Password

1. Make It Long

Aim for at least 16 characters. Length matters more than odd symbols.

2. Try a Passphrase

String together four or five random words, like a silly sentence. Passphrases are long and easier to remember.

3. Make Each One Unique

Never reuse a password. If one site leaks, the rest stay safe.

4. Avoid Personal Details

Skip birthdays, names and addresses. Hackers can find these online.

Use a Password Manager

A password manager creates strong passwords and saves them in a secure vault. You only need to remember one main password.

Prices and plans for these apps may change, so check before you sign up.

Many browsers and phones include a built-in password manager. Standalone apps are also available.

Add Two-Step Login and Passkeys

Two-step login, also called multi-factor authentication, asks for a second proof that it is really you. That may be a code from an app or a tap on your phone.

The Cybersecurity and Infrastructure Security Agency (CISA) explains how to turn on multifactor authentication.

Passkeys go a step further. They let you sign in with your face, fingerprint or device personal identification number (PIN) instead of a password. Turn them on where sites offer them.

Use this calculator to check your password length.

What to Do After a Data Breach

If a company you use reports a breach, change that password right away. Also change it anywhere else you used it.

Report identity theft at IdentityTheft.gov.

Turn on two-step login and watch your accounts for unusual activity.

• Use 16 or more characters
• Make every password unique
• Set up a password manager
• Turn on two-step login
• Add passkeys where offered
• Update passwords after any breach

Common Password Mistakes

Many people make the same password mistakes. Avoiding them makes your accounts much safer.

Fixing even one of these habits improves your security. Start with your most important accounts.

How Hackers Get Passwords

Knowing how passwords get stolen helps you protect them.

Data Breaches

Hackers break into company systems and steal lists of passwords. If you reused a password, they try it on other sites.

Phishing

Scammers send fake emails or texts that look real. They trick you into typing your password on a fake site.

Guessing Attacks

Computers try thousands of common passwords quickly. Short or simple passwords fall first.

Malware

Harmful software can record what you type. Keep your devices updated and avoid unknown downloads.

Prioritize Your Most Important Accounts

You do not need to fix every password at once. Start with the accounts that matter most.

• Email. It can reset passwords for most other accounts.
• Banking and payment apps. They protect your money.
• Phone carrier account. Scammers target it to steal your number.
• Cloud storage. It holds photos and documents.
• Social media. Hacked accounts can scam your friends.

Give each of these a long, unique password. Turn on two-step login for all of them.

If you forget a password, recovery options help you get back in. Set them up before you need them.

Add a recovery email and phone number to important accounts. Keep them up to date.

Save backup codes in a safe place at home. Some people keep them in a locked drawer or a password manager.

Avoid security questions with answers people can find online, like your hometown. Some people use fake answers stored in their password manager.

Check Whether Your Passwords Were Exposed

Change any password marked as exposed or reused. Start with your email and banking accounts.

Help Family Members Stay Safe

Older relatives and kids are common targets for scams. Share simple password tips with them.

Help them set up a password manager. Show them how to save and fill in passwords.

Write down the master password and store it somewhere safe at home. Make sure they know where to find it.

Teach kids never to share passwords with friends. Explain that real companies will never ask for passwords by text or email.

Plan for the Unexpected

Think about what happens if you cannot access your accounts because of illness or an emergency.

Some password managers let you name an emergency contact. That person can request access if needed.

Keep a list of your most important accounts for trusted family members. Store it securely, not in plain text on your computer.

Make Good Habits Stick

Strong passwords work best as part of a routine. Small habits keep you protected over time.

Review your password manager’s security report every few months. Update weak or reused passwords.

Delete accounts you no longer use. Fewer accounts mean fewer chances for hackers.

Passwords for Shared Family Accounts

Families often share streaming, shopping and Wi-Fi accounts. Handle these passwords with care.

Use a password manager that lets you share specific passwords with family members. It avoids sending passwords by text.

Change shared passwords when someone moves out or a relationship ends. Remove old devices from the account too.

Give kids their own profiles when services allow it. Profiles keep settings and history separate without sharing the main password.

Protect Your Wi-Fi Network

Your home Wi-Fi password protects every device on your network. Change the default password that came with your router.

Use a long passphrase and the strongest security setting your router offers. Create a separate guest network for visitors.

Password Mistakes to Avoid

Some habits make your accounts easy targets. Watch out for these common mistakes.

• Using the same password for many accounts
• Using names or birthdays in passwords
• Writing passwords on sticky notes near your computer
• Sharing passwords by text or email

Use a password manager to create and store strong passwords. It remembers them for you.

Teach Your Family Good Habits

Strong passwords protect the whole family. Share simple tips with everyone at home.

Help kids create long passphrases they can remember. Show older relatives how to use a password manager.
