Password Generator

Create a strong, random password with adjustable length and character sets — generated locally with your browser's cryptographic RNG.

—

Strength: Weak0 bits of entropy

Length16

Uppercase (A-Z)Lowercase (a-z)Numbers (0-9)Symbols (!@#$…)

Exclude ambiguous characters (I, l, 1, O, 0)

Generated with your browser's cryptographic RNG — never sent over the network.

Frequently asked questions

Is this actually random?+

Yes — passwords are generated with the Web Crypto API's crypto.getRandomValues(), a cryptographically secure random number generator, not Math.random().

Are passwords sent anywhere or stored?+

No. Every password is generated locally in your browser and never transmitted or logged.

What does the strength meter measure?+

A rough entropy estimate based on password length and the size of the character set used — longer passwords with mixed character types score higher.
