Use a Password Manager

Actions

1. 1 Choose a password manager (iCloud Keychain is built-in, 1Password and Bitwarden are great alternatives)
2. 2 For iCloud Keychain: Settings → Passwords → enable AutoFill Passwords
3. 3 Import any saved passwords from your browser
4. 4 Let the manager generate new passwords when you change accounts
5. 5 Enable the security audit feature to find weak/reused passwords
6. 6 Gradually replace weak passwords with strong, unique ones

Context

81% of data breaches involve weak or reused passwords. When you use the same password across multiple sites, a breach at one site compromises all your accounts. Password managers solve this by generating and storing unique 20+ character passwords for every account. You only need to remember one master password. Apple's built-in iCloud Keychain makes this seamless on iOS—it's free and already on your device.

Using unique passwords for every account means that a breach at one site can never compromise your other accounts. Period.
