Frequently Asked Questions about Password Generator

Are generated passwords stored or logged anywhere?

No! Passwords are generated 100% locally in your browser memory and are never transmitted over the internet.

What makes a password strong?

A strong password should be long (16+ characters) and combine uppercase letters, lowercase letters, numbers, and special symbols to maximize bit entropy against brute-force attacks.
