Open Password GeneratorFrequently Asked Questions
How secure are these passwords?
Very secure. They use crypto.getRandomValues() which provides cryptographically secure randomness, the same API used by password managers.
Is my generated password stored anywhere?
No. The password exists only in your browser memory and is never transmitted to any server.
How long should my password be?
16+ characters with mixed types is considered very strong. At 20+ characters with all character types, brute-force attacks are infeasible with current technology.
