Free Password Generator
Generate a secure, random password with the length and character types you choose.
How to use this tool
Adjust the length slider (or type an exact value) and toggle which character types to include: uppercase letters, lowercase letters, numbers, and symbols. The password updates instantly whenever you change an option, or click the refresh icon to generate a new password with the same settings.
Click the copy icon next to the password field to copy it to your clipboard. The strength badge below the password gives a quick read on how hard it would be to crack, based on its length and character variety.
Use this tool to create strong, unique passwords for new accounts, replace weak or reused passwords, or generate temporary passwords that meet a site's character requirements.
FAQ
- Is this password generator secure?
- Yes. Passwords are generated using your browser's cryptographically secure random number generator (crypto.getRandomValues), and every password is created entirely on your device.
- Are generated passwords stored or sent anywhere?
- No. Nothing is uploaded, logged, or saved. Once you leave or refresh the page, the generated password is gone unless you copied it.
- How is password strength calculated?
- Strength is estimated from the password's entropy, based on its length and how many character types (uppercase, lowercase, numbers, symbols) are included. Longer passwords with more character variety score higher.
- What length should I use for a strong password?
- Most security guidance recommends at least 12-16 characters with a mix of uppercase, lowercase, numbers, and symbols for a strong, hard-to-guess password.
