i liked the physical authenticators better. the process to setup the phone app version is impossible to complete, and to make matters worse, blizzard is starting to require you to have this set up to access certain feature in the game. but what can you expect from a company that uses top dollar revenue to maintain a game using junkyard parts from the lowest bidder.

This app used to work alot better. The one touch authentication was convenient. However over the past few months it gets caught in a loop where it requests approval, only to clear the password and make you start again. This can happen several times in a row. I have opened tickets and filled bug reports, yet this still isn't fixed. Despite having account hacking issues in the past, the developer really doesn't seem concerned about fixing this.

Complete garbage app, didn't work on my old phone, still doesn't work on my new phone. I get the "Setting Up.." infinite loading screen problem for both. I've tried some solutions but nothing has worked. I get daily email notifications that someone is trying to steal my account, and I can't even get two factor authentication? What a complete joke.
