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 for a network or cellular connection.

Ratings and Reviews
Risky Choice for 2FA
Using an authenticator app for 2FA is seen as a top choice for securing access to sensitive accounts over other methods. However, when the app stops loading, and instead crashes on open, you can easily lose access to these accounts if you’re relying on the app for 2FA and you don’t have backup methods configured (or physically accessible to you in the moment). This app is quite terrible in terms of its support and user experience. It did work, at one point, and now it doesn’t which means that I can never rely on it again. I’ve been slowing shifting to the Microsoft Authenticator app which has a superior user experience and feature set, is substantially more reliable, and works. I would not use this app if I were you.
Terrible mfa application. The absolute worst.
Use any other MFA app, but this one. It does not save your information. If you change phones or migrate phone platforms, you are completely screwed unless you remove mfa from all your apps before you uninstall the Google Authenticator app. And if you lose your phone, you are just screwed with no recourse.
If you use the Microsoft Authenticator, at least it will remember your information while you are on the same phone platform. But Google? Nope. Don’t even bother to ask for help because all you will receive is arrogant script kiddies belittling you for something you didn’t even know you were supposed to do. I’ll be uninstalling many Google apps in the coming month. I can definitely do without you at least Microsoft has support for the products they make. Imagine if GM made you ask other car owners how to use the windshield wipers, or how to change a tire. Google’s arrogance is amazing. I’ll make use of capitalism and find a better mouse trap.
No Cloud Backup
There are many reviews complaining that deleting the app, migrating to a new device, etc… lost access to their 2-factor auth codes. This is exactly what you want from a security perspective! That is precisely why I rated this app with 5 stars. Very few 2-factor apps do not backup to the cloud and this is one of them. No question that cloud backup is extremely convenient but there is often a trade-off between convenience and security and this is a great example of that. This app is for those who choose a bit of extra security (codes only stored on the device) over the convenience of having their codes stored both on the device and in the cloud.
