I have found that an Apple Watch keeps me from touching my phone much of the time. Things like verifying an OTP or determining whether or not a notification is important are just a glance at my watch.
I've started leaving my phone in a different room, using it as a continuity camera, or literally tossing it on my chair or bed before sitting down to work, but inevitably I'll need it for 2FA via Google Authenticator— maybe it's time to move 2FA to another device, and once it's on my desk, it often gets picked up out of habit.
