Frequently asked questions
Are these passwords safe to use?+
Yes. They are generated with your browser's cryptographically secure random generator and never leave your device. For best security, store them in a password manager.
How long should my password be?+
At least 12–16 characters. Longer passwords with a mix of character types are dramatically harder to crack.
Is the password sent to a server?+
No. Generation happens entirely in your browser, so the password is never transmitted or logged anywhere.
Do you store the passwords?+
No. Nothing is stored. Once you close the page, the password is gone unless you saved it yourself.
