About these tools

Make a strong password, check a file’s fingerprint, generate IDs, or pick a random winner. Quick, free, and no sign-up.

For a password generator, privacy isn’t a bonus — it’s the whole point. Everything here is created right on your device and never sent anywhere, so nobody else ever sees the password you just made.

The randomness comes from the same secure source your browser uses for its own security, not the weak kind used in games.

Questions people ask

Should I use this instead of my password manager?

Your password manager’s generator is great — use it if you have one. This is for when you need a strong password and don’t have one handy.

Can anyone else see what I generate here?

No. Everything is created on your device and nothing is sent anywhere.

How random is it really?

Very. It uses crypto.getRandomValues, the secure random source built for exactly this job, not Math.random.
