Frequently Asked Questions
Why use a passphrase instead of a random password?
Passphrases are easier to memorize while providing equivalent or better security. A 4-word passphrase from a 512-word list provides ~36 bits of entropy — comparable to a 6-character random password — but is much easier to type and remember.
Is the generation truly random?
Yes. All random selections use crypto.getRandomValues(), the browser's cryptographically secure random number generator.
