I hear you! I HATE having to have my phone at my fingertips all the time. I try to remember that I'm adding steps. Yes, my authenticator is a phone app but I don't have to use it often so am prepared to have the phone available. My choice was to use my fingerprint which is how I protect my phone. It can get annoying but I now automatically pick it up with my left hand and my fingertip goes right to the spot.
I still have a landline for my business and will keep it until I retire. I leave my cell on vibrate and the sound off about 90% of the time. It annoys some folks trying to reach me because they have to leave a message. And I don't answer unidentified calls on either phone. Since I don't have every contact ever in my cell, lots of calls are unidentified and not all callers leave a message. Also my cell isolates identified spam calls very effectively.
