NOTE: THIS IS FOR THE OLD REPUBLIC!!
okay, now that i've made this clear and won't get random WoW authenticator comments: I'm thinking about getting the Android authenticator for my Galaxy S4. However, after my previous phone had the tendency to crash every 2 months, meaning I lost all my installed apps, settings, messages and the like, I only want to do this if I'm sure it won't cause me issues.
specifically: If I have the mobile authenticator app on my phone, and my phone crashes to the extent that I lose all my installed apps and settings, can I just reinstall the app from my installed app list in the Play Store and continue like nothing happened? Or is every authenticator installation with a unique code, even if it's the same device and the same Google account that installs it?
