What this does

Password Generator produces strong, random passwords using your browser's cryptographically secure random number generator. Nothing is sent to any server — your password is generated entirely on your device.

When to use it

  • Creating a new password for a website signup
  • Generating passwords in bulk for team accounts
  • Creating a strong master password for your password manager
  • Replacing an old, weak, or breached password

Frequently asked

How long should my password be?

At least 16 characters for important accounts. Length matters more than special characters — a 20-character lowercase password is stronger than an 8-character mixed-case one with symbols.

Is this safe to use?

Yes. Passwords are generated locally with crypto.getRandomValues() (the same secure source browsers use for HTTPS). They never leave your device — Uvelia can't see them.
