This tool calculates the entropy and assesses the complexity of numerical passwords (passwords composed of digits only). Enter your numerical password in the field below and click "Check Password Strength" to analyze its strength. Entropy is a measure of the randomness and unpredictability of the password, measured in bits. Higher entropy generally indicates a stronger password. Complexity is a qualitative assessment based on password length and simple patterns (like repeating or sequential digits). Note that this is a simplified complexity measure for numerical passwords.
