Password Generator

Strong random passwords using your browser's cryptographic RNG. Never sent to a server.

What this does

Generates a strong random password using window.crypto.getRandomValues — the same CSPRNG (cryptographically secure RNG) browsers use for crypto operations. Nothing is sent to a server; the password exists only in your browser memory until you copy it. Adjust length and character sets to fit the rules of whatever account you're protecting.

Tips

Aim for 16+ characters with all four sets enabled — that's effectively uncrackable today.
"Exclude similar" avoids characters that look alike (1 vs l vs I, 0 vs O) — handy if you ever have to dictate the password.
Store every password in a manager (Bitwarden, 1Password, etc.). Reusing passwords is the #1 cause of account takeover.
