Frequently asked questions
Is this password truly random?
Yes. It uses crypto.getRandomValues(), the browser's cryptographically secure random number generator (CSPRNG). This is the same source of randomness used by operating systems for key generation.
Is my generated password stored anywhere?
No. The password exists only in your browser's memory. It is never stored, logged, or transmitted. If you close the page, the password is gone forever.
How long should a password be?
For most accounts, 16-20 characters is recommended. For high-security applications, use 32+ characters. Length is more important than complexity.
