When using the nbtbank com Bank Mobile App to login to your account, there are several things to keep in mind. If you are having trouble logging into the app, the server may be down. If that is the case, try again after a few minutes. If this does not fix the problem, you might be entering the wrong login credentials. Another possible reason is that you may have used an incorrect password or security question. To find out why this happens, you should check the status of your data connection or your third-party social network service. Then, if you see an error message, you can review the details that are displayed to determine if you have entered the wrong information.
