Features of Password Generator

Instantly generate strong, secure passwords or random strings directly in your browser. Simply adjust the length slider or toggle character types, and 10 new passwords will be generated in real-time.

Open details

You can generate passwords up to 64 characters long, choosing any combination of uppercase letters, lowercase letters, numbers, and symbols. The "Exclude similar chars" option helps prevent typos by removing look-alike characters (such as uppercase 'I', lowercase 'l', number '1', uppercase 'O', and number '0').

Frequently asked questions

How are the passwords generated?

This tool uses a cryptographically secure random number generator (Web Crypto API's crypto.getRandomValues) to ensure high randomness and security.

What does "Exclude similar chars" mean?

It removes characters that are easy to confuse when reading or typing manually, such as uppercase "I", lowercase "l", number "1", uppercase "O", and number "0".
