Instant generation
Real-time strength feedback
Secure randomness
Web Crypto API powered
Very secure! We use the Web Crypto API for cryptographically strong random number generation. Random passwords with mixed characters provide high entropy, while memorable passwords use the EFF's curated wordlist with 7,776 words for excellent security.
Random passwords use a mix of characters (letters, numbers, symbols) for maximum entropy in minimum length. Memorable passwords use dictionary words that are easier to remember and type, while still providing strong security through length and randomness.
No, all password generation happens entirely in your browser. No passwords are stored, logged, or transmitted to any server. Each password is generated fresh when you request it.
Strong passwords have high entropy (randomness). For random passwords, use 16+ characters with mixed types. For memorable passwords, use 4+ words. The strength meter shows real-time feedback based on the entropy of your password settings.
