What is Password Entropy?

Entropy is a mathematical measurement of a password's unpredictability. It calculates the bits of information based on the length of the string and the size of the character set used. Higher entropy scores mean brute-force computer software will take longer to crack the code.

Our checker calculates this entirely locally via standard algorithms. Rest assured that no text entered in this widget is saved or shared online.
