What is Password Generator?
Create passwords that are genuinely hard to guess. Choose the length and character types, and each password is generated using your browser’s cryptographically secure random number generator — not the predictable randomness most simple generators rely on.
How to use Password Generator
- Set the password length. Sixteen characters or more is a sensible minimum today.
- Toggle which character types to include: lowercase, uppercase, digits and symbols.
- Check the strength meter and entropy estimate below the password.
- Click “Copy password”, or “Regenerate” for a different one.
Why use this tool?
Cryptographically secure
Passwords come from crypto.getRandomValues, the browser’s secure randomness source, rather than Math.random which is predictable and unsuitable for security.
Entropy you can judge
The strength meter shows estimated bits of entropy, a far more meaningful measure than a vague “weak/strong” label.
Never transmitted
The password is generated and displayed on your device only. Nothing is logged, stored or sent — which is exactly what you want from a password tool.
Frequently asked questions
How long should my password be?
At least 16 characters with mixed character types for important accounts. Length contributes more to strength than complexity does, so a longer password beats a short one full of symbols.
Is it safe to generate passwords in a browser?
Yes, when generation uses the Web Crypto API as this tool does, and nothing is transmitted. Store the result in a password manager rather than reusing it from memory.
