Password Generator
Random
Create secure passwords using your browser's cryptographic random generator. Choose the length and character types, optionally exclude look-alike characters, and check the estimated strength. Passwords are never stored, logged, or transmitted — close the tab and they're gone.
How to use
- Set the desired length with the slider.
- Choose which character types to include.
- Optionally exclude ambiguous characters like I, l, 1, O, 0.
- Check the strength indicator.
- Copy the password, or regenerate for a new one.
Frequently asked questions
- Are generated passwords stored?
- Never. This tool keeps nothing — passwords exist only in your browser tab and are not saved or sent anywhere.
- How random are they?
- They use the Web Crypto API (crypto.getRandomValues), a cryptographically secure source — not Math.random.
- How is strength measured?
- By entropy: the password length multiplied by the bits per character from your selected character set.
- Why exclude ambiguous characters?
- Characters like I, l, 1, O, and 0 are easy to confuse when typing or reading a password aloud.
