How strong are the generated passwords?

Each password is generated using cryptographically secure random number generation (CSPRNG), providing maximum entropy for security.

Are my passwords stored or logged?

No! All password generation happens locally in your browser. We never store, transmit, or log any passwords.

What makes a password strong?

Strong passwords use a mix of uppercase letters, lowercase letters, numbers, and symbols. Our 16-character passwords provide 128+ bits of entropy.
