I love this app and I have used it for many years  but I format my phone every now and then and that's when I run into trouble. I end up with a bunch of different authenticator codes to multiple sites and apps  and when I lose this app  I lose them ALL. There's no way to backup or recover a loss with this service  while that may be a good security feature  it's a kick in the balls for me.
