How to use the Password Generator
- Choose a length — 16 or more characters is recommended.
- Select which character types to include.
- Copy the password and store it in a password manager.
How it works
Passwords are built with crypto.getRandomValues, the browser's cryptographically secure random generator, entirely on your device.
Strength is estimated as entropy: length × log₂(alphabet size) bits. 75+ bits is very hard to brute-force.
Frequently asked questions
Is it safe to generate passwords online?
This generator runs only in your browser; passwords are never transmitted or stored. Still, use a reputable password manager to keep them.
How long should a password be?
At least 12–16 random characters, or a passphrase of 4–6 random words. Use a different password for every site.
