Functional at Best. Use Authy app instead This app is the minimum you would expect. It's functional  but that's it. If you want cloud sync to your computer  or just a backup of your codes in case your phone is stolen  or you want to switch phones without resetting your two factor authentication codes for every account  use Authy app instead. I also prefer Authy's UI  but that comes down to personal preference. Google Authenticator would have a smaller learning curve.
