Great security tool - free necessity

Works 99.9% of the time for me, keeps my stuff safe. I was hacked long ago when frozen throne dropped. Got it to prove I valued my items and I’m sure blizzard appreciated it, because I appreciated them giving me my things back. The one thing I cannot stand however.. when you login to bnet the authentication picture of the iPhone and the finger has the buttons flip flopped. So if your looking at the picture and not your phone. You will decline your request. Not sure why this hasn’t been addressed wish I could upload a photo to easily explain as well but here we are. Petty complaint I know but it still baffles me. If this gets fix I’d be inclined to give a 5 star. Great idea bliz, even the innovation of a simple click instead of the tedious 8 digit number of earlier stages.

The app works, but...

The app works as intended. However, every month or so, Blizzard has issues with their authentication servers for World of Warcraft. Players with an authenticator attached to their accounts are unable to login to either the Legion mobile app and/or their main World of Warcraft account. I do not know if this has affected Overwatch, Destiny 2, or Blizzard's other games. The issue is usually resolved within 12 hours, but it is frustrating to wait.

This app will prevent someone else from logging onto your account. It will not protect you from being unable to log on to your own account if Blizzard has internal authentication issues (again). The benefits outweigh the risks. Just be aware this app will occasionally backfire and prevent you from playing.

Does the job well, but missing a key feature

Obviously, the authenticator does what it needs to.. Authenticates. But after sooo many years, blizzard had not developed a mobile app for messaging friends on the battle net client??? This would be such an easy feature to add since this is already linked to your account, but yet it hasn't been done. Riot did it YEARS ago and it got an amazing response. Blizzard needs to step it up, this project should take no longer than a week.
