Free, private password and passphrase generators that never leave your browserPricing:
- Free
- 100% Client-Side Generation - Every password, passphrase, and PIN is generated entirely in your browser using the Web Crypto API. Nothing is ever transmitted to a server, logged, or stored, not even temporarily.
- Six Generator Tools in One Suite - A complete toolkit covering Passphrase Generator, Random Password Generator, Memorable Password Generator, Strong Password Generator, PIN Generator, and XKCD Password Generator, no need to jump between separate tools or sites.
- Live Entropy and Strength Scoring - Every generated result shows real entropy in bits alongside a clear Weak, Fair, Strong, or Very Strong rating, so you know exactly how secure your result actually is, not just how complex it looks.
- Enforced Minimum Strength - The Strong Password Generator won't let you accidentally generate a weak result, a minimum length and character-type floor is built into the generation logic itself, not just suggested in the UI.
- Weak Pattern Avoidance - The PIN Generator automatically avoids common weak sequences like 1234 or 0000, so every PIN generated is genuinely random, not just numerically valid.
