What makes a password strong
A strong password is long, random, and uses a mix of character types. This tool generates passwords with the Web Crypto API (cryptographically secure randomness), not Math.random().

Tips for better results
Review options before generating. Click again if you need another candidate. Prefer copying instead of screenshotting secrets.
Privacy and offline-friendly processing
Whenever possible, Password Generator processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.
