Abstract
Techniques real-time adaptive password policies are presented. Patterns for passwords are regularly analyzed along with other factors associated with the patterns to dynamically determine password strength values. The strength values can change over time based on usage statistics. When a strength value falls below an acceptable threshold, passwords associated with that particular pattern can be downgraded or rejected in real-time and existing policy can be adapted to reflect the undesirability of that pattern.
