Generate a strong random password with the length and character types you choose, for a new account, a password manager entry, or anywhere you need one fast. Built on the Web Crypto API's cryptographically secure random number generator, not Math.random(), so it's safe to use for real passwords -- and nothing you generate is ever sent anywhere, it's all done in your browser.
This generator builds a random password from 4 to 64 characters, with a choice of uppercase, lowercase, numbers, and symbols, drawn from the Web Crypto API's cryptographically secure random number generator (crypto.getRandomValues) rather than Math.random().
Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.
It's used for new account signups, password manager entries, temporary or shared-use credentials, and anywhere else a strong, unguessable password is needed fast without reusing an old one.
Generate draws each character using crypto.getRandomValues with rejection sampling (so no character in the pool is ever slightly more likely than another), guarantees at least one character from every enabled type, fills the rest of the length from the combined pool, and shuffles the result -- all done locally in your browser, with nothing ever sent anywhere.
Yes -- it uses the same cryptographically secure randomness (crypto.getRandomValues) that's used for encryption keys, not Math.random(), which is fast but not designed to be unpredictable.
No -- everything happens locally in your browser. Nothing you generate is transmitted or logged anywhere.
Yes -- toggle uppercase, lowercase, numbers, and symbols independently, and set any length from 4 to 64 characters.
Yes -- at least one character from each enabled type is guaranteed before the rest of the length is filled and shuffled.
