About Password Generator
Create cryptographically strong passwords with fully customizable rules: choose length (8-128 characters), toggle uppercase, lowercase, numbers, and special characters, and exclude similar-looking characters (like l, 1, I, O, 0).

Frequently Asked Questions
- How strong are the generated passwords?
- Passwords use your browser's cryptographically-secure random number generator, making them as unpredictable as mathematically possible. A 20-character password with all character types has roughly 6.6 × 10^38 possible combinations.
- Should I generate a new password for every site?
- Yes — unique passwords per site prevent credential stuffing attacks where one breach compromises all your accounts. Use a password manager to store them.
