Frequently Asked Questions
Why is crypto.getRandomValues() safer than Math.random() for passwords?
Math.random() is pseudo-random and predictable. The Web Crypto API uses cryptographically secure pseudo-random number generators (CSPRNG) seeded by physical hardware entropy from your device OS.
Are generated passwords saved or sent over the internet?
Never. Passwords are generated in your local device memory and exist only on your screen until you copy them. We have zero servers logging generated credentials.
What password length is considered unbreakable today?
A password with 16 or more mixed characters (letters, numbers, symbols) provides over 95 bits of entropy, which would take quantum supercomputers trillions of years to brute force.
