Use unique passwords and a password manager
Long, unique passwords (or passphrases) for every account — stored in a password manager so you are not reusing secrets across sites.
Why it matters
Reused passwords let one breach unlock many accounts. CISA and NIST emphasize length and uniqueness over complex composition rules. A password manager helps you create and remember strong, distinct credentials.
Practical steps
- Install a reputable password manager and protect the vault with a long, unique master passphrase.
- Generate a unique password for each important account. Prefer longer passphrases when you must memorize one.
- Replace reused or known-breached passwords, starting with email and financial accounts.
- Do not store password hints that strangers could guess from social media.
- Where the service supports it, combine the password manager with MFA or move high-value accounts to passkeys.
