Password Strength Checker
Analyze the strength of any password: length, character classes, entropy in bits and resistance estimate. Processed in the browser — the password never leaves your device.
How is the strength calculated?
A força é medida pela entropia em bits: quanto maior, mais difícil é adivinhar a senha por força bruta. A entropia considera o comprimento e as classes de caracteres utilizadas (minúsculas, maiúsculas, dígitos, símbolos). Uma senha com 60+ bits de entropia é considerada forte para a maioria dos usos.
