Frequently Asked Questions

Are these password generators safe to use?

Yes. The best generators create passwords locally in your browser using the Web Crypto API — nothing is ever sent to a server.

What makes a password strong?

Length matters most. A 16+ character password mixing upper and lowercase letters, numbers, and symbols would take centuries to brute-force.

Do these tools store the passwords they generate?

No. A trustworthy generator never stores or transmits generated passwords — always save yours in a password manager.
