NT Password lockouts

By alissa.burch ·
Currently our system locks a user out after 10 bad password attempts. We are looking to change that number to 3 attempts. Has anyone reduced their lockout limit lately? If so, can you quantify the impact it had on the number of password resets your support group had to handle?

NT Password lockouts

by timwalsh In reply to NT Password lockouts

This is one of those questions that is not likely to gain you any useful information.

How often are you needing to reset passwords now? Do they tend to be the same users?

In my experience, most bad password entries occure because the user is either in too much of a hurry (typing errors) or has Caps Lock turned on. If a user can't figure this out after a couple of prompts...

If you are truly concerned about increased workload, try changing to an intermediate number (say 5), and monitoring the impact. Also realize that password resets (or at least account unlocks) are likely to be more numerous after a forced password change (this can also vary based on the required password length).

If you had many lockouts at 10, it is safe to say you should expect an increase. The key will be an education program of your users, make sure they know the proper logon techniques, to check for caps lock ? You could also check the lockout duration to make sure it is not too long. 3 tries in 15 minutes with a 30 minute lockout might be a good start. You don?t want to compromise security for convenience.

Good luck
