Strong Password Generator

What is this tool?

This strong password generator creates random passwords with configurable length and character groups. It uses the browser's cryptographic random number generator rather than Math.random, which is important for secrets.

Length matters more than visual complexity, but many systems still enforce character-class rules. The toggles let you include or exclude uppercase letters, lowercase letters, digits, and symbols while keeping the generated value random.

Generated passwords are intentionally not memorable. Store them in a password manager, do not reuse them across services, and prefer longer values when a password protects high-value accounts or infrastructure.

How to use

1. Choose a password length with the slider.
2. Enable or disable uppercase letters, lowercase letters, digits, and symbols to match the target system's rules.
3. Click Refresh to generate a new value.
4. Copy the password directly into a password manager or secure secret store.
