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.

Gav I thinkable he'd of me ,

Great! Works! Most of the time...

I have been using this specific app only for authenticating(obviously) but when ever I am in an area with little to no internet connection he app doesn't connect, when every other app works. NOTE, this almost never happens. But I tend to go on many trips and I constantly have to re-log in so I can play hearthstone and going in and out of internet with plane trips.

Hah you just read my entire review, thanks.
