Random Password Generator

Summary

This tool uses the browser's built-in WebCrypto API to generate truly random passwords that are impossible to predict. You control every aspect: length from 4 to 128 characters, and which character sets to include — uppercase letters, lowercase letters, digits, and symbols. All generation happens entirely in your browser; no password ever leaves your device.

How it works

1. Select the desired password length using the slider or input field.
2. Toggle which character sets to include: uppercase, lowercase, digits, and/or symbols.
3. Click "Generate Password" after choosing your settings to create a fresh password.
4. The password is created using window.crypto.getRandomValues() for cryptographic randomness.
5. Click "Copy" to copy the password to your clipboard instantly.
6. Generate as many passwords as you need — each one is unique and secure.
