Simple and works

Set it up, link it to your account, you're good to go.
If you want to prevent being locked out of your own account in the future, it will happen, write down the serial number. Some day you'll delete the app, ruin your phone, or simply upgrade to a new phone and get locked out. Then you'll come running here to write a terrible review because you didn't read the instructions which says to write down the serial number. If you've made it this far and still don't have that SN wrote down you should go write it down now.

After hearing about all the hacking on diablo 3, I was a bit worried about my account security. So I decided to install the authenticator for my account security. This app is easy to use and in a few minutes you will have a secure account. So far do good, my lvl 52 monk has not been hacked since. If you love to play blizzard games, secure your account.


This app does exactly what it is intended for. I have had absolutely no issues so far. For those with serial number issues, all you have to do is contact Blizzard, go through a couple verification questions and they will gladly register your new serial for you. I have done it twice due to purchasing new phones. Mobile Authenticator
