How this password generator works
Every password is generated locally in your browser using the Web Crypto API — the same cryptographically secure random number source used by security software. No password is ever transmitted, stored, or logged. Disconnect from the internet and it still works.
Password vs. passphrase — which should you use?
Random password
Best for accounts stored in a password manager. A 16+ character random password with mixed character types is effectively impossible to brute-force.
Passphrase
Best for passwords you must remember and type — your password manager's master password, device logins, or Wi-Fi. Four to five random words are both stronger and easier to remember than a short complex password.
Password safety tips
Use a unique password for every account — reuse is how one breach becomes ten. Store them in a reputable password manager. Turn on two-factor authentication wherever it's offered. And never share passwords over email or chat.
