Abstract:
Measuring the strength of passwords is crucial to ensure the security of password-based authentication. However, current password strength meters have limited accuracy and are too simple to gauge the complexity of passwords. We present the concept of adaptivepassword strength meters that estimate passwordstrength using Markov-models.
