How it works
Generate strong, unique passwords instantly with full control over length and character sets. Cryptographically secure and generated locally — your passwords never leave your device.
Use the slider to choose a length between 4 and 128 characters. 16+ is recommended for strong security.
Enable lowercase, uppercase, numbers and symbols. Optionally exclude ambiguous characters.
Click generate. The password is created with cryptographic randomness, then copy it to your clipboard.
Examples & Data
| Length | Types | Entropy |
|---|---|---|
| 8 | lower + digits | ~38 bits |
| 12 | lower + upper + digits | ~66 bits |
| 16 | All + symbols | ~95 bits |
| 24 | All + symbols | ~142 bits |
Example: Kx!9#mP2@vLq7$dR — 16 chars, ~95 bits of entropy.
