Hi All,

Following on from my earlier email - I've the following question now :

I can enforce that the user can't use the same password as the previous four
- when they change their password.  However, the user can manipulate this by
changing the password four times and then resetting back to there original
password.  How would I overcome this problem ? Any thoughts or
recommendations ?

Store the date/time that the password was changed, and as well as not alllowing one within the past four passwords you can also disallow one that was last used within the past N days, for whatever value of N you prefer.
