WhatsApp now supports multi-device use for all Android and iOS users. This allows WhatsApp to be used on as many as four devices, without the need to be connected to a smartphone.
Multi-device support can be enabled by joining the multi-device beta. Open WhatsApp on iPhone. Next, select Settings -> Link Devices. Select Multi-Device Beta and then tap Join Beta. After that, you can start linking devices.
Once your devices have been linked, messages can now be sent and received via the WhatsApp desktop app and web-based service. Your phone won't need to remain online any longer, but it is not possible to delete or modify conversations from a connected device.
Notably, you cannot message, call, or send a text from the web, portal, or desktop to users with an older version of WhatsApp. You can also only have one WhatsApp account connected to one phone at a time. All personal calls and messages are encrypted between devices.
Your linked devices will be removed if your phone isn't used for more than 14 days. WhatsApp warns users that this beta feature may cause some issues with the service's performance and quality. However, they can always leave the beta program at any time.
WhatsApp is working on an iPad version, according to reports. Meta-owned company Meta has suggested that multi-device support will help bring the iPad version closer to release.
