Last Tuesday my phone died mid-flight to Denver and I got locked out of my email, bank, and work VPN all at once. The authenticator app was on the dead phone and my backup codes were saved in a note on the same device, real genius move. Took 3 hours on customer support lines to verify my identity with old statements and a notarized form. Now I keep a printed code sheet in my safe and test the restore process every 6 months. Anyone else learn this lesson the hard way or did I just win the dumbest setup of the year?
