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.

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.

Easy, simple way to protect you BNet account, with no BS.

Heres the deal: if you BNet account is valuable to you, and theres a chance someone could get into you account, you can use this super simple app that, believ it or not, is even simpler than Steam mobile auth. Even though a BNet account is nowhere bear as valuable as most Steam accounts, this app is still a nice precaution to have, and is easy to use and set up.
