What Is the Password Generator?
The Password Generator creates strong, unpredictable passwords using your browser's cryptographically secure random number generator (window.crypto), not a weaker pseudo-random function. You control the length and which character types are included — uppercase letters, lowercase letters, numbers, and symbols — so you can match whatever requirements a website or app demands.
Reusing simple, guessable passwords is one of the most common security mistakes people make. A strong, randomly generated password for every account is one of the simplest ways to protect yourself, especially when paired with a password manager. Because password generation happens entirely in your browser, nothing you generate is ever transmitted, logged, or stored anywhere.
How To Use the Password Generator
Set your password length — Drag the slider to choose a password length between 4 and 64 characters.
Choose character types — Toggle uppercase, lowercase, numbers and symbols on or off to match site requirements.
Generate and copy — Click Regenerate for a new password, then copy it with one click.
