About Password Generator

The Password Generator creates random passwords to your specification. Set the length and toggle which character classes to include — uppercase, lowercase, digits, and symbols — then generate a password and copy it for use in a password manager or new account.

Passwords are produced locally using the browser's cryptographic random source and are never transmitted to or stored on a server. Longer passwords with a wider mix of character types are harder to guess or brute-force, so increasing the length is the simplest way to strengthen the result.

Frequently asked questions

Are the passwords stored anywhere?
No. Each password is generated in your browser and is gone once you close or refresh the page.
How long should my password be?
Longer is stronger; 16 characters or more with mixed character types is a reasonable target for most accounts.
Is the randomness secure?
Yes. The tool uses the browser's cryptographic random generator rather than a predictable pseudo-random source.
