Features include:
- Automatic setup via QR code
- Support for multiple accounts

Customer Reviews

If you have saved codes don't update.

This review is based solely on the multiple times I've had issues with them updating the app and then you lose all codes you use to access accounts. You then can't reach any support personnel to resolve the situation. They had this same issue in the past and requested not to update to that specific version till they fixed it. Yet they continue to have this issue on every update. I've had multiple codes generated and still can't get into some accounts due to them resetting the app every time. Even with a phone backup they're gone. They refuse to fix the issue this time and yet Authy provides better service just not enough support with other sites.

Jeopardize all your gmail accounts with this app.

I've used Google Authenticator for over 3 years and lost over 10 gmail accounts because it keeps resetting without retaining the codes created by the user for each account stored in the app.

Earlier this year I've created 5 new gmails accounts entered into Google Authenticator hoping it wouldn't reset itself when it updates. I was wrong. It reset and deleted everything I stored in the app.

Now I no longer have access all my gmail accounts and I'm now hassling with alternative ways to enter all 5 of my accounts. DO NOT TRUST THIS APP UNLESS YOU WANT TO LOSE ALL YOUR VALUABLE INFORMATION, INCLUDED IN YOUR EMAIL ACCOUNTS.

A serious pain when switching phones

I had this problem on an earlier version of this app. You get a new phone, it is back to square one. There is no restore or saving of codes. It is a great app other than the fact that it becomes a nightmare if you get a new phone or have to restore your phone. They need to incorporate some kind of save system so you don't have to painstakingly disable and reenable every single 2 step verification you had previously.
