How long to crack it?

A quick, eye-opening estimate of how long a password could resist a brute-force attack — and a clear picture of why length and variety matter. Everything is calculated on your device.

Estimated time to crack

  • • Length matters most — each extra character multiplies the difficulty.
  • • Mixing upper/lowercase, numbers, and symbols widens the search space.
  • • A long passphrase of random words beats a short complex password.

🔒 Calculated entirely in your browser — nothing is sent or saved. This is an order-of-magnitude estimate for a brute-force attack. Real attackers try common passwords, leaked passwords, and dictionary words first, so a reused or common password can fall instantly no matter what the math says. Always use a unique password per account.
