Methodology
We evaluate your password using Entropy Analysis and Brute-Force Simulation.
Entropy Calculation
Entropy measures the unpredictability of a password. We calculate it using the formula: E = L * log2(R), where L is length and R is the character pool size.
Dictionary Attacks
Hackers don't guess randomly. They use lists of billions of common phrases and leaked passwords. If your password is a common word, its entropy is practically zero.
