About the Secure Password & Passphrase Generator

Generates un-crackable, high-entropy passwords using your browser's cryptographically secure pseudo-random number generator (window.crypto).

How to Use

Select your desired password length (8 to 64 chars) and toggle uppercase, lowercase, numbers, and special symbols.

Understanding Results

A password with over 80 bits of entropy would take trillions of years for current supercomputers to brute-force.

Frequently Asked Questions

Are generated passwords saved?

Never. All passwords are generated purely in client-side RAM and vanish when you close the tab.
