How to Create a Strong Password

  1. Adjust the Password Length slider (16 characters or more is recommended for critical accounts).
  2. Select which character types to include: Uppercase, Lowercase, Numbers, and Symbols.
  3. Optionally check Avoid Ambiguous to exclude look-alike characters (0, O, I, l, 1) when typing passwords manually.
  4. Click Copy to copy the password directly to your clipboard, or switch to Bulk (5) to generate multiple passwords at once.

Password Entropy & Security Reference

Length (Mixed Charset) Entropy Recommended Use Case
12 characters ~78 bits Standard websites and low-risk accounts
16 characters ~104 bits Email, banking, cloud dashboards, and social accounts
24–32+ characters 156–208+ bits Master passwords, database credentials, API secrets

Frequently Asked Questions

Is this password generator safe to use?

Yes. It runs 100% locally in your browser using window.crypto.getRandomValues(), ensuring true cryptographic randomness without ever sending generated passwords over the network.

Should I reuse generated passwords across different sites?

Never reuse passwords. Generate a unique random password for every website and store them inside an encrypted password manager so a data breach on one service cannot compromise your other accounts.
