- WhatsApp has finally rolled out multi-beta support to beta testers.
- This feature is available in the latest beta version of WhatsApp for a number of users.
- The company also details how this feature works, the changes to the WhatsApp architecture needed, and how it works for users.
It’s almost here. The long-awaited multi-device WhatsApp support has emerged as an experimental feature. Facebook’s engineering team made the announcement this week while detailing how the complex works of this feature.
Per Facebook, multi -device support prompted a “rethink” of the chat app architecture.
How multi -device support works
Previously, WhatsApp saw major smartphones as a “source of authorization” – a device used as a platform for encrypting such user accounts. This forces the device to always be available, even when a companion device, such as a PC connected to the WhatsApp Web, is in use.
Now, Facebook has redesigned the system. WhatsApp’s new architecture ensures that companion devices can act independently while also maintaining synchronization with major smartphones if possible.
“Multiple WhatsApp devices use a customer -fanout approach, where a WhatsApp customer who sends a message encrypts and sends it N times to N number of different devices – which are on the list of sender and receiver devices,” explained Facebook’s engineering team.
This design allows users to send messages or make calls from a companion device even if their primary smartphone is turned off or disconnected.
Through this setting, WhatsApp is also able to sync app data and message history across devices without relying on a central server. However, the company keeps “a copy of each application that states that all devices a person can access” on the server for redundancy. The company states that this data is “encrypted from end to end with an ever -changing key that is known only by the person’s device.”
What is not included
Annoyingly, users are allowed up to four companion devices on their account, but none of which can be smartphones. This makes this feature a lame duck for those who want to use one WhatsApp account on two smartphones.
Beta also lacks key features. Initially, you won’t be able to see other users ’direct locations on the companion device, and you also won’t be able to call other people from the companion device if they install a dated version of WhatsApp. Group invitation handling is limited to major smartphones for now as well. There is also limited functionality for Portal, Desktop WhatsApp, and Business WhatsApp users.
How to activate the beta of various WhatsApp devices
If you are already using the WhatsApp beta channel, make sure you update your app. After this, you can check if the feature registration options are available on your device. To create this:
- Open WhatsApp.
- Type More options menu – a three -button menu in the upper right corner.
- Type Linked Devices.
- Select Multi -device beta.
- Type Join the beta.
Multi -device beta options will only be visible if the feature is available to you. Although I received the beta version of WhatsApp, the feature is not available on my device.
If you want to leave the beta, you can do so too. Follow the same steps above, but tap Leave the beta otherwise in the last step.
WhatsApp has yet to announce when multi -device support is expected to build stable. We imagine the company still has some bugs to squeeze and functionality to polish. Even so, after months of rumors and teasing, the beta launch is the first feeling that multi-device support is almost ready to begin.
