Again, we are not talking about banks or banking. In my country one's bank app functions as the strong authentication used to log in to all the other services where one has to prove one's identity. And yes, pretty much every day while I am on the go, I have to authenticate to some service or another.
Again YOU are choosing to live that lifestyle of on-the-go always phone-in-hand. The inability to stop using the phone while desiring to not do phone activities is not because of the banking/authentication.
