Generate high-entropy passwords with a strength indicator showing the exact bit count. A strong password is long, uses all character types, and is unique to every account. This tool creates all three in your browser.
The tool uses crypto.getRandomValues(), the browser's built-in cryptographically secure random number generator, to select characters or words. No library is required and our servers are not involved. The password is generated entirely inside your browser tab.
All generation runs locally in your browser. The password exists only in your browser until you copy it. You can prove this yourselfin your browser's DevTools Network tab.
For hashing the generated secret for storage, try the hash generator. To create random opaque identifiers instead, use the UUID generator. For encoding generated tokens for transport, see Base64.
Strength comes from entropy, the number of possible combinations. A 24-character password using all character types has roughly 157 bits of entropy, making it effectively impossible to crack with current technology.
The password is generated and stays entirely in your browser. Our servers are not involved at any point.
Entropy in bits = password length × log2(character set size). For a 24-character password using all 95 printable ASCII characters, that is 24 × log2(95) ≈ 157 bits.
Yes. This is the recommended approach. Generate a unique, random password for every account and save it in a reputable password manager such as Bitwarden, 1Password, or Dashlane.
