About Password Generator
Weak passwords are responsible for over 80% of data breaches. Our Password Generator creates cryptographically strong, truly random passwords that are virtually impossible to crack, even with modern computing power.
All password generation happens in your browser using the Web Crypto API — the same cryptographic standard used by banks and governments. Your generated passwords are never transmitted to any server.
Password strength explained A 12-character password using all character types (uppercase, lowercase, numbers, symbols) has approximately 5.9 × 10^23 possible combinations. At 1 trillion guesses per second (state-of-the-art hardware), it would take 18 million years to crack by brute force.
Passphrase generation We also support passphrase generation — memorable combinations of random words like "correct-horse-battery-staple". Passphrases are both easier to remember and cryptographically stronger than most passwords.
