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.

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.
Essential App, But No Cloud Backup
This is one of the most essential apps on my phone. I don’t know why I trust Google with my 2FA codes (I don’t really) but this is a very useful and important app. It is pretty basic as far as apps go, but it works for the intended purpose.
They just added the ability to transfer 2FA codes when upgrading to a new phone. They released this feature less than a month after the second wave of new iPhones came out… so less than a month ago I did the transfer manually, turning 2FA off and back on for my new phone across a dozen services. Some were easy to transfer, others were the opposite. It took over an hour. Their timing with this feature is awful, but at least it’s here now I suppose.
