Free Strong Password Generator
A strong password is long, random and unique to each account. This generator creates passwords in your browser using your device's cryptographic random number generator, so the result is never sent to a server or saved anywhere.
Pick a length from 8 to 64 characters, choose which character types to include and copy the result. A built-in strength meter shows how hard the password would be to guess, and passphrase mode builds memorable multi-word passwords.

Frequently asked questions
How long should my password be?
At least 14 to 16 characters. Longer is better, and length matters more than complexity.
Is this password generator safe?
Yes. Passwords are generated locally with the Web Crypto API and are never transmitted or stored.
Should I reuse passwords?
No. Use a unique password for every account and keep them in a password manager.
What is a passphrase?
A password made of several random words. It is long, easy to remember and hard to crack.
