Google Authenticator 4+

Google LLC

    • Free



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 mobile 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

This is certainly a handy security feature that I’ve used for a while now. However Google needs to implement or integrate a system to use it with your Google account so you don’t lose codes if something goes wrong with your device and have lost passcode’s. Hopefully this is something Google will consider integrating. This is the only reason for my four stars

Awful and Google does not care

I would give this zero stars if I could. I was hit by the bug with this app following the iOS15 upgrade. Lost access to accounts that I am struggling to recover and will be hit financially. Google don’t appear to be acknowledging this issue as I suspect they cannot recover the keys that have been lost. So even though someone from Google will read this review they would never respond to it. They are hoping it blows over. This is a complete failure in the Google QA procedures and as from a support perspective most of us would be understanding, to a degree, if they just admitted their failure and assisted where they can, if at all possible. I’ve lost trust in Google because of this and will reviewing private and business use of Google services and where I need to move to other providers that seem to have more robust QA procedures and actually seem to just care a little bit.

Finally I can log in and save my codes to my account. The amount of times I’ve had to reset my phone, or changed phone and lost the codes and had to go one by one and update is ridiculous. Slightly less secure for some, but honestly the pain of having to go an find back up codes and what not is worse than the risk.
