Until now, WhatsApp users could use one account on one phone and multiple desktop devices.
WhatsApp users can now link up to 4 phones to their account and easily switch between them without signing out.
Each phone connects to WhatsApp independently, making sure that all calls, personal messages, media files, and other data are synced across devices and end-to-end encrypted. If the user's primary device is inactive for a long time, WhatsApp will automatically log them out of all companion devices.
The update is being rolled out to WhatsApp users globally. The company is also rolling out a new way to link devices using a one-time code.
Last year, the messenger introduced the ability for users to message seamlessly across all their devices.
