Google Authenticator works with 2-Step Verification for your Google Account to provide an additional layer of security when signing in.

With 2-Step Verification, signing into your account will require both your password and a verification code you can generate with this app. Once configured, you can get verification codes without the need of a network or cellular connection.

Features include:
- Automatic setup via QR code
- Support for multiple accounts
- Support for time-based and counter-based code generation

To use Google Authenticator, you need to enable 2-Step Verification on your Google Account. Visit to get started.

Good, until you lose your backup.

You have to encrypt with a password to iTunes when you swap to a new iOS device, otherwise your access to all your accounts will be lost, unless you printed a recovery key.

It's a great and useful app, until a random bug deletes one of your accounts and you lose access to it forever. This is what happened. One day I have TeamViewer, the next it's vanished.

Just don’t upgrade your iPhone

I was very pleased with this app until I had to upgrade my iPhone ( thanks apple for screwing up my old iPhone battery) so I now a new iPhone but it doesn’t automatically transfer the google authenticator app details. I then I found a online guide to transfer my authenticator details from one phone to the other. On the instructions I advised me to access my google account etc etc I tried to access my google account and yes I had access via my new phone but no It won’t let me alter any details there and asks for my password which I 100% entered correct but it is refusing to accept it so I figured ah ok I’ll reset my password, that’s a no go too . So now I’m reduced to writing this review to vent a little as I’m currently loosing money by not being able to access my financial apps (thanks google) .

Amazing app!

I use google authenticator for many services, and it is extremely secure! It is easy to use and makes your account nearly impossible to hack, however you must disable it if you get a new phone as the accounts cannot be transferred over, and I did loose access to my google account due to getting a new phone, and leaving it enabled
