Generate cryptographically secure random passwords and API secrets using Web Crypto entropy.
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.
