WhatsApp’s promises of being able to use your account on up to four devices with a single account are now within the reach of Android users.
The latest Android beta, WhatsApp version 2.23.8.2 or later, brings the mode active Companion Mode that allows you to enable WhatsApp on different devices without stopping working on the previous one.
To date it was only active in the latest beta but for a group of test users. Now it reaches all beta users. We are not talking about WhatsApp Web, which is already functional for all users, but the complete application.
If you have multiple Android devices, you can now access your WhatsApp account from all of them at the same time.
How Companion Mode works
To be able to use Companion Mode you have to install the latest WhatsApp beta, for this you have to sign up for the app’s testing program by simply pressing the button Become a Betatester from their website.
After that you can update WhatsApp from Play Store on your device and you can now activate Companion Web in the application.
In WhatsApp, the process is different from other applications such as Telegram, which is worth entering the credentials, and you have to go through a few steps to read a QR code and give permission to the secondary device.
Let’s see the steps to activate Companion Mode:
Right now you can only activate this mode on an Android device, so your primary device can be iPhone or any Android, but your secondary has to be an Android device with this beta.
The first step is to open the application on your new device with the beta installed, start the configuration and when it asks for the phone number, press the three dots and choose Link Device.
After that, a QR code appears that you will have to read with your main mobile after choosing settings -> linked devices.

And well, after loading the chats on your secondary mobile you will be able to access the WhatsApp application on your Android smartphone as if it were the main one, without problem.
As we can see, it is a process that we only have to do once and if we later want to stop using the secondary device, we can always remove the authentication from the same option Linked Devices.
