It used to be all I had to do to set up a new phone was say restore from backup. I have many services tied to two factor authentication. I use several apps on my phone for that.
Nowadays that means before I can switch phones I have to remember to install the 2FA applications and configure them prior to wiping out the old phone. The challenge is that most of these apps do not restore when you restore from backup. That’s actually a good thing for security reasons however it is a gotcha I need to remember to pay attention to.
I was reminded of this when I got my iPhone XS Max for a few days last year before I decided to return it and keep my iPhone X.
Now I hope that I remember this critical step when I do eventually replace my iPhone.
