There are a couple different ways your A-State account can get locked.
The Astate account and the Duo account should unlock themselves after 30 minutes. Your PIN will never unlock itself. If you are needing your PIN unlocked or if you want your Astate or Duo accounts unlocked sooner, you can give the ITS Helpdesk or the IT Store a call and we can help you. Be sure that you are aware of your Security Questions because that is how we have to identify you in order to unlock your account for security purposes.
