Authenticator has options that avoid approval fatigue. There's a setting that causes it to show a number on screen, and then an option between providing a list of 3 numbers you have to pick from or showing a textbox that you have to type the displayed number into. If it's set up for textbox entry it's unlikely that someone is going to approve a random request.
