This would have saved me a lot of mental anguish about 2 years ago, my phone screen died and I needed about 5 authenticators that were on it just to clock in at my (remote) job and get to what I needed to do the job.
Eventually I solved the issue by blind navigating to screen brightness and turning it all the way up, this made the screen act normal until I could replace it.
The lesson here is to not have a single point of such large failure, like I did.
