Frequently Asked Questions
Yes. We use Web Crypto API's getRandomValues(), the same cryptographically secure method used by 1Password and Bitwarden. Passwords are generated in your browser and never transmitted anywhere.
Entropy measures randomness in bits. A 40-bit password can be cracked in seconds; 100-bit takes billions of years. We recommend 70+ bits for important accounts.
Use Random for passwords stored in a password manager. Use Memorable for passwords you type often, like your master password or laptop login.
Password history is stored only in your browser's localStorage. It never leaves your device. We recommend using a proper password manager for long-term storage.
Humans are predictable. We substitute letters with numbers ('p@ssw0rd'), use common words, and create patterns. Crypto RNG creates truly random, unguessable passwords.
For maximum security: 16+ characters with all character types. For memorable passphrases: 4+ random words. Length matters more than complexity.
