Password generator
Random passwords with the length and character set you choose.
-Everything runs in your browser. No file is ever uploaded to a server.
- 1Drag the slider to set the length, from 6 to 48 characters.
- 2Check or uncheck lowercase, uppercase, numbers and symbols.
- 3A new password generates automatically. Click the refresh icon anytime for another one.
- 4Click the copy icon to copy it to your clipboard.
Is the randomness actually secure, or just Math.random()?+
It uses the Web Crypto API (crypto.getRandomValues), the same cryptographically secure source browsers use for encryption keys, not the predictable Math.random(). Generation happens locally, so the password never crosses the network.
What decides whether a password is rated Weak, Medium or Strong?+
A combination of length and how many character types you've enabled: a short password using only lowercase letters rates Weak, while a long one mixing all four types rates Strong. Push the length slider up or tick more boxes to improve the score.
Which symbols does the generator use?+
!@#$%^&*()_+-=[]{}?. Toggle the symbols checkbox on or off depending on whether the site or system you're using accepts special characters.
