SECURITY BENCH
Score a supplied password by length, character class variety (lower, upper, digit, symbol), and a coarse entropy approximation. The score is an educational estimate, not a substitute for a real password manager or breach-database check.
WHAT THIS DOES
Runs entirely in your browser.
/tools/password-strengthpassword-strengthv4.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of password and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
Length contributes the dominant factor; each character class adds bonus entropy. The score is bucketed into Very Weak, Weak, Fair, Strong, Very Strong.
Boundary: This is a coarse local estimator. It does not check breached-password databases, perform dictionary attacks, or model attacker capability.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. UtilityForge is a local workbench. Use a real password manager and authentication system for credentials.
No. The password strength estimator runs locally; nothing is sent to UtilityForge.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: Password are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: Password (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
This is a coarse local estimator. It does not check breached-password databases, perform dictionary attacks, or model attacker capability.
