Problems with iOS 10.0.2!

Im having problems with logging on with the four digit passcode, I was very happy logging into my accounts this way but now I have to type a username and password every time. Im very sad because it takes too much time to log in the new way versus the previous way. Please fix the problem and bring back the pass key login option. Even after I log in with full username/password I have to go to other options such as Home or Deposit from main menu to view Accounts. Im sad sad sad :-( but hopeful the problem is fixed.
