Analyse password strength and crack time estimate. Password Strength Tester is a free online tool from the ToolsRift Hash & Crypto Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Type a password and the tester scores it live, estimating entropy and brute-force crack time without ever sending the password anywhere.
From length, character variety and entropy in bits, then converted into an estimated brute-force cracking time.
Yes — the analysis runs entirely in your browser and nothing is transmitted or stored.
Length above all — a long passphrase beats a short password with symbols. Aim for 16 or more characters.
