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.
