Frequently asked questions
How random is this password generator?
It uses your browser’s cryptographically secure random number generator (the Web Crypto API), which is designed for generating unpredictable values — not a weaker pseudo-random function.
What makes a password “strong”?
Length matters most, followed by variety. Mixing uppercase, lowercase, numbers, and symbols across 12+ characters makes a password dramatically harder to guess than a longer password using only one character type.
Why exclude ambiguous characters?
Characters like 0/O, 1/l/I, and | can be hard to tell apart in some fonts. Excluding them makes a password easier to type accurately when reading it off a screen or a printout.
Is my password stored or sent anywhere?
No. Every password is generated entirely in your browser and never leaves your device — nothing is transmitted or logged.
