How it works
Strong passwords, locally
Cryptographic randomness
Each character is chosen with your browser's crypto.getRandomValues — the same unpredictable source operating systems use for keys. No patterns, no seeds, no repeats.
Character-set guarantees
When you tick uppercase, lowercase, digits and symbols, the generator makes sure at least one character from each set appears — so the result always matches the policy you set.
Nothing leaves the browser
Generation happens entirely on your device. The password is never uploaded, stored on a server, or logged — it exists only on your screen until you copy it.
Questions
Password generator FAQ
How long should my password be?
12 characters is a sensible minimum for most accounts; 16 or more for anything sensitive. Each extra character multiplies the time needed to crack it — length beats complexity.
Can I exclude similar-looking characters?
Yes — tick Exclude ambiguous to drop I l 1 O 0. Handy when you have to read a password off one screen and type it on another.
Is this safe to use for real accounts?
It produces genuinely random output using your browser's secure generator. For maximum safety, generate the password on a trusted device, copy it straight into your password manager, and never reuse it.
