Customer Reviews

You've out done it again Google!

This apps authenticator is so easy and fast, way convenience (no more annoying text's ringtone or vibration for me). I'm so glad I decided to give it a try. I would give a 10 stars if there is one ;). If you haven't installed on your device then you're missing out.

Failure with Microsoft

App was supposed to generate numbers that would work for two-step authentication for Microsoft accounts. The generated numbers looked great. Really slick. Just one problem. The numbers did not work. So in my case, perhaps user error on my part although this looks so simple as to be fool proof, Google generated codes that just didn't work. Not sure why Microsoft didn't recognize the codes Google generated for it. But I had to two-step authenticate a different way.

Great App

I saw somebody using Google Authenticator on TV and downloaded it, ever since I have been using it. Overall, it works excellently but I would like if a fingerprint or passcode option was added along with landscape mode.
