Google Authenticator adds an extra layer of security to your online accounts by adding a second step of verification when you sign in. This means that in addition to your password, you'll also need to enter a code that is generated by the Google Authenticator app on your phone. The verification code can be generated by the Google Authenticator app on your phone, even if you don't have a network or cellular connection. • Sync your Authenticator codes to your Google Account and across your devices. This way, you can always access them even if you lose your phone. • Set up your Authenticator accounts automatically with a QR code. This is quick and easy, and it helps to ensure that your codes are set up correctly. • Support for multiple accounts. You can use the Authenticator app to manage multiple accounts, so you don't have to switch between apps every time you need to sign in. • Support for time-based and counter-based code generation. You can choose the type of code generation that best suits your needs. • Transfer accounts between devices with a QR code. This is a convenient way to move your accounts to a new device. To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. To get started visit http://www.google.com/2step

App works great but asking for a review while working in the app can be a bit frustrating but otherwise great work

Terrible no backs automatically so you lose every thing.

I love the app and have no problems with it. But when buying a new iPhone, Apple says all apps transfer but they only transfer the app itself. You must move all your codes manually. This really screwed me up. I trusted Apple to transfer the codes along with the authenticator app and then could not get into any of my accounts.

Exactly how I needed it.

I thought Google Authenticator had forgotten how to focus an iPhone's camera, because the native camera app was still working as usual. But when a competitor's app did the same thing, I realized it was Apple's fault. I had to zoom in on screenshots for the app to be able to read them.

For those interested, TOTP works completely offline. I just ordered a 3" mini phone, which I intend to use as such. It has 2 GB of RAM and Android 8.1, so it's not a good daily driver. But if you disable all the radios (cellular, Wi-Fi, Bluetooth), you can use it as an air-gapped TOTP device while keeping your password manager on your daily driver, separating the two keys.

If you do this, just make sure you back up your keys (export QR codes or secret keys for each account). When the offline device dies or gets lost/stolen, you'll need redundancy.
