100% private — files never leave your deviceHow to use

- Generate. Click Generate to create one or several passwords instantly in your browser.
- Copy and use. Copy a password with one click. Nothing is stored or uploaded, so it stays private.

- Nothing leaves your device. Every password is created locally in your browser and is never transmitted or logged.
- Fully configurable. Control length and character sets, and exclude ambiguous characters like 0, O, 1 and l.
- Live strength meter. See the estimated entropy in bits so you can judge how strong each password is.

Frequently asked questions
Is this password generator free?
Yes, it's completely free with no sign-up and no limits.
Are the passwords sent anywhere?
No. Passwords are generated locally in your browser using the Web Crypto API and are never uploaded, stored or logged.
Are they actually secure?
Yes. They use crypto.getRandomValues, the browser's cryptographically secure random source, with rejection sampling to avoid statistical bias.
What length should I choose?
For most accounts 16 characters or more is strong. For high-value accounts, longer is better — the strength meter shows the entropy.
What does excluding look-alikes do?
It removes easily confused characters like 0/O and 1/l/I, which is handy when a password must be typed or read aloud.
Do I need to install anything?
No. It runs entirely in your web browser with nothing to download or install.
