This tool generates passwords using the Web Cryptography API (crypto.getRandomValues()) built into your browser. This is the same randomness standard used by security professionals and generates true cryptographic randomness — far stronger than simple Math.random(). Your password is generated entirely in your browser and is never transmitted to any server.
Password strength comes from two factors: length and character variety. A 16-character password using uppercase, lowercase, numbers, and symbols has over 10²⁸ possible combinations — practically impossible to crack by brute force. For highly sensitive accounts (banking, email, work), use 20+ characters. For less critical accounts, 12–16 characters is fine.
Yes. Since strong passwords are impossible to memorize, use a password manager (like Bitwarden, 1Password, or Dashlane) to store them securely. Generate a unique password for every account, and use this tool each time you need a new one. Never reuse passwords across sites.
// Is my password safe? Could someone see it?
Your password is generated and displayed entirely in your browser. Nothing is sent to our servers — there are no server-side logs, no analytics capturing the output, and no storage of any kind. The page works fully offline once loaded.
// How long should my password be?
For most accounts: 16+ characters. For email, banking, and work accounts: 20+ characters. For master passwords (password manager, encryption): 24–32 characters. Longer is always stronger.
// Why exclude ambiguous characters?
Characters like 0 (zero) and O (letter O), or l (lowercase L) and 1 (one) look identical in many fonts. If you ever need to type your password manually, enabling this option prevents transcription errors.
// Is this better than using a phrase?
Both are valid. Random character passwords (like those generated here) are mathematically stronger per character. Passphrases (like "correct-horse-battery-staple") are easier to remember. For most people using a password manager, random character passwords are the better choice since you don't need to memorize them.
