Google Authenticator is the official Google two-step authentication (2FA) app, thanks to which you can add an extra layer of security to any app or service. In essence, this means that all the services you link to this multifactor authentication system will not only need your usual password, but will also require the use of this app. This way, you can bolster the security of your most important accounts in seconds.
Easy to configure
The first thing you need to do after installing Google Authenticator is configure and link the accounts you want to protect. To do so, you have several options. You can import lists from a previous device, create one by hand or scan the QR code of the service you want to protect. The latter option is the easiest, as you just have to point the camera at the QR code to link them automatically. Entering the code by hand is a bit more cumbersome, as you will have to type in the exact code, which is usually more than ten digits long.
Importing and exporting codes is very easy
As mentioned above, Google Authenticator allows you to import code lists. It's very easy to do; simply access the drop-down menu on the left, tap the Transfer Codes button, and choose the Import Codes option. After that, all you have to do is scan the QR code of the device you want to transfer the codes from and you're done. Of course, you can also export your list of authentication codes. Doing so is equally simple: Choose which codes you want to send and allow another device to scan your QR code. This is the best option when setting up a new phone.
Two-step authentication on desktop
Some users have doubts about whether it is possible to use the Google Authenticator app to access desktop apps and services, whether on Windows, Linux or Mac. Of course you can. Thanks to this app you can manage all the profiles with 2FA set up and access them easily, regardless of the platform. Whether you are trying to open an iPhone app or a PC app, you will have no problem if you use this app.
High compatibility with accounts
Google Authenticator offers extensive support for all kinds of providers and services, including Google, Facebook, Instagram, Twitter (X), Dropbox, Firebase, Microsoft and many others. After linking all your profiles you will receive an automatic notification every time you try to access them on a new device.
