Internal testing for multi-device support on Whatsapp started in July and a whole series of testing was done. After that it has been brought to the users. This feature gives you access to connect your instant messaging account to a secondary device – such as a PC, laptop or Facebook portal. It enables end-to-end encryption, especially on chats that take place using a secondary device. This means that neither Whatsapp nor any third party can read the messages you send or receive on your connected PC.
By providing standalone support, WhatsApp allows users to send and receive messages on their secondary devices, even when they are not near their phones. This feature also helps you stay connected to WhatsApp if your phone runs out of charge.
How to link your WhatsApp account to a secondary device
Before getting started with the steps below, it’s important to note that you’ll need to download the latest WhatsApp version (if you don’t have the latest update) to get multi-device support and link your account to a secondary device. This feature is currently in ‘beta’ as well and thus, there may be issues regarding its stability for some time. Apart from this, it is limited to Whatsapp Web, Desktop and Portal. This means that WhatsApp has not yet enabled support for linking Android phones or iPhones as secondary devices. You cannot connect your WhatsApp account to an Android tablet or iPad using multi-device support at this time.
You can join Multi Device Beta by going to WhatsApp- Settings > Linked Devices > Multi-Device Beta
Once done, Linked devices Go back to the screen and then to link a new device Link a Device Tap on the button.
Now you have to scan the QR code available on your secondary device to link it with your Whatsapp account.
After linking, Whatsapp will allow you to send and receive messages using your secondary device. You will also be able to view your past messages from the secondary device. However, messages deleted from your primary device will not be visible on the secondary device. Messages you delete from your secondary device also won’t appear on your phone. However, this feature does not work with the iPhone.
