Frequently Asked Questions
How secure are these passwords?
Passwords are generated using crypto.getRandomValues() — a cryptographically secure random number generator built into your browser. They never leave your device.
What length should I use?
16+ characters with all character types is considered strong. For sensitive accounts, use 20+ characters.
What are ambiguous characters?
Characters like 0/O, 1/l/I that look similar in some fonts. Excluding them makes passwords easier to read and type manually.
Can I generate multiple passwords at once?
Yes! Enable bulk mode to generate 5, 10, or 20 passwords at once.
Is my password stored anywhere?
No. Everything runs locally in your browser. No data is sent to any server. The history is only kept in memory during your session.
