How do I prevent a user from re-using the same password within a certain period of time? How do I prevent a user from re-using the same password within a certain period of time?

I have configured a number of password restriction modules {Password policy, Generate Password and Flood control} which I have configured to do things like "Password must not match any of the user's previous 10 passwords" but I can't configure them to prevent the same password from being reused within a certain period of time like a year.

I am using Drupal 7.
You are looking to alter Password policy module:

A password policy can be defined with a set of constraints which must be met before a user password change will be accepted. Each constraint has a parameter allowing for the minimum number of valid conditions which must be met before the constraint is satisfied.
Current constraints include:

History constraint (checks hashed password against a collection of users previous hashed passwords looking for recent duplicates)


Now, all you need is to take this constrain and make a copy based on time, not number. Should be pretty easy, real difference is in one WHERE condition.
If module provides hooks, make it in your custom module. If it does not, provide a patch with your constrain.
