About this app

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 Permission notice: Camera: Needed to add accounts using QR codes

It seems Google Authenticator is facing some trouble lately. I can't take a screenshot "due to privacy policy" or I would share this visually. All codes on my account are no longer being displayed, and even when they were displayed, they were rejected by the platforms I needed to access, being described as invalid. I don't know what's happening. Without these codes, I can't access my ByBit and Namecheap accounts. I seriously need a quick resolution of this issue.

While this app is great, it still needs an important improvement in the area of restoring the app in case of loss or formatting of device. I recently had to format my device because of a malfunction. Now I have lost access to some of my accounts secured on the app. There should be a way of restoring the app through email or phone number instead of putting it solely on importing

The app is great. But if the developer are reading through review. I believe there's more to contribute for the proper usage of this app. If my phone got missing, there should be a way of accessing my account without waiting to import and export. It happened to someone recently. Her phone was stolen and when she got another phone, there is no way to access this app unless she import which is impossible. I believe more update can be done regarding that. Thank you 😊
