FAQ

How random is the generated password?
Passwords are generated with your browser's Web Crypto API. That is cryptographically secure randomness, not a predictable Math.random call.
Are generated passwords stored or sent anywhere?
No. Passwords are generated locally in your browser and never leave your device.
What length should I use?
12 characters or more with mixed character sets is a solid baseline. Use 16+ for important accounts like banking or email.
Why can't I deselect every character set?
The generator needs at least one character set enabled. Otherwise there is nothing to build the password from.
