Google Authenticator

By Google, Inc.

Open iTunes to buy and download apps.


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.

Requires iOS 5.0 or later.

What's New in Version 2.3.0

* Minor UI refresh with support for iOS 8 and the iPhone 6 Plus.
* Small bug fixes.

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.

Wish you could organize logins into folders

I use the app A LOT. I have OTP with all my clients websites and personal sites. Not to mention and other google accounts that I have. Works for me no issues. Just hard to find the one I need at times and it would be nice to have folders or bins to organize them into.

People having time issues. Check your PC/Mac's time. If you went through DST or maybe the PCs time is off then the OTP won't work properly.


I’ve had no issues with this authentication app. I had another one, that will remain nameless, simply because they have an Apple Watch app. But, that one crapped out on more than one occasion. Not with Google. Every time I’ve needed it, Google’s been there to get me logged in.

The only reason I didn’t rate this as 5 stars, is I believe they need to create an Apple Watch app. If they do, I’ll write another review and give them 5 stars!
