Password Generator
About Password Generator
A 16-character password drawn from a 90-character alphabet has roughly 100 bits of entropy — beyond brute-force reach for any realistic attacker. Passphrases hit similar entropy with words you can actually remember.
Frequently asked questions
- Is randomness here cryptographically secure?
- Yes. Passwords come from crypto.getRandomValues, the browser's CSPRNG.
- Should I use a password generator instead of my password manager?
- Use whatever your password manager provides. This tool is for cases where you can't reach your manager — generating a one-off Wi-Fi or recovery code, for example.
