The long-promised Companion Mode is finally rolling out to all the beta testers after being released to a limited number of users on the beta version. The feature is an extension of multi-device support that has been designed to allow users to link their existing WhatsApp account to another mobile phone.
More Details on the Companion Mode Features
With the companion mode, users can access their chats on the second device without requiring an active Internet connection on the main phone. At the moment, the second device can only be an Android phone (or a tablet) as the companion mode is not currently available on WhatsApp for iOS.
In order to link a secondary Android mobile device, you need to follow these steps:
• On your secondary Android mobile phone, download the latest beta of WhatsApp Messenger or WhatsApp Business from the Google Play Store.
• Tap the overflow menu within the registration screen and you should finally see the option “Link a device”.
• Open WhatsApp on your primary device, and tap Settings > Linked devices.
• Point this device to your secondary mobile phone to capture the QR Code.
It is pertinent to mention here that you can link up to four devices at once. It should also be noted that all personal messages and calls remain end-to-end encrypted even when using WhatsApp from a linked mobile phone. So, whenever someone sends you a message, it is sent to all your devices while maintaining encryption.
