Google Authenticator 4+


    • 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

The perfect authentication system for almost any app!

Google Authenticator is perfect for almost every app that requires, requests or allows for authentication to be used! With a very simple, user-friendly interface and easy setup, it’s very handy! What makes it better than every other authentication app is that you can easily access your authentication codes anywhere, as they’re automatically connected to your google account, allowing you to sign into it on almost any device, almost anywhere. It’s really helpful and I use it in my day-to-day life. Appreciate it google, keep making amazing apps like this! ❤️

Easy peace of mind

So many activities online need 2FA these days and an Authenticator like this really makes life easier at times. But should you not have your phone handy, sometimes it can be a pain. When updating or changing phones always make sure you have you logins associated with an Authenticator sorted or you’ll find yourself not being able to login. A smallish price to pay for a bit more security in these times of human scum trying to steal everything you have worked for!

Just don’t wipe your accounts

A lot of 1 star reviews come from people who wiped their accounts on their old phone and can no longer authenticate their accounts.

But if you don’t do that then this app is totally secure and does what it’s supposed to, and it’s safe to ignore the very low rating for this app.
