Password Generator FAQ

Are the generated passwords secure?
Yes! We use the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. This is the same technology used by security applications and password managers.
Is my data safe?
Absolutely! All password generation happens directly in your browser. No passwords are ever sent to our servers or stored anywhere. You can even use this tool offline.
How long should my password be?
We recommend at least 16 characters for most accounts, and 20+ characters for sensitive accounts like banking or email. The longer the password, the harder it is to crack.
