About Password Strength Checker
Password Strength Checker is a no-nonsense utility for engineers and technical marketers. Score password strength and estimate time to crack, entirely in your browser. Give it your value and it returns a 0–100 score with a breakdown — no sign-up, no ceremony.
The conversion is exact and reversible, so you can round-trip a value to confirm nothing was lost.
Password Strength Checker is included on Professional and above. Every run counts against your plan's credit allowance, and results are saved to your history so you can return to them or attach them to a client report.
