Password Generator

Generate a strong, random password right in your browser. Choose the length, pick which character types to include — uppercase, lowercase, digits and symbols — and optionally exclude look-alike characters like the letter l, the number 1, capital O and zero. Every password is produced with the Web Crypto API’s crypto.getRandomValues, a cryptographically secure random source — never the predictable Math.random that weaker tools use. We also show you the exact entropy in bits so you can see, in real numbers, how hard the password is to guess, rather than trusting a vague coloured bar. Unlike the generators built by password-manager companies, this tool sells you nothing and stores nothing: the password is created on your device and is never transmitted, logged or saved — we literally cannot see it. Prefer something you can remember? Switch to the memorable mode to build a passphrase from random everyday words.

How it works

1. Pick the length and the character types you want to include.
2. Optionally turn on “exclude look-alike characters” to avoid l/1/I/O/0 confusion.
3. Read the entropy in bits — higher is stronger. Hit Regenerate for a fresh one.
4. Click Copy. The password was generated in your browser and never left your device.
