What is this tool?

When to use it

  • Creating a new account and needing a strong, unique password
  • Replacing a weak or reused password with a stronger one
  • Generating passwords that meet a specific site's character requirements
  • Creating multiple unique passwords for different accounts
  • Generating a temporary password to share securely with a teammate

  2. 2Choose which character types to include: uppercase letters, lowercase letters, numbers, and symbols.
  3. 3Click generate to create a new random password.
  4. 4Copy the password and store it in a password manager, then generate a new one anytime.

Frequently asked questions

Are generated passwords sent to a server or logged anywhere?

No. Password generation happens entirely client-side in your browser, and generated passwords are never transmitted or stored.

Can I control which character types are included?

Yes. You can toggle uppercase letters, lowercase letters, numbers, and symbols independently.

Should I reuse the same generated password across multiple sites?

No. Best practice is to use a unique password for each account, ideally stored in a password manager.

How do I know if my generated password is strong enough?

You can check it with the companion Password Strength Checker, which evaluates length and character variety.
