Now, linked devices will be able to receive and send messages up to 14 days after the main smartphone goes offline. Plus, messages and calls are still end-to-end encrypted. Once linked, it behaves pretty much the same way, except you'll be able to chat regardless of whether your main smartphone is online or not. Once enabled, you'll be unlinked from all devices before re-linking to a new device. When enabling this feature on your smartphone, you need to opt into the feature - labeled as still in 'Beta'. Previously, you had to make sure your main smartphone was still connected to the internet before you could carry a conversation on your linked web browser.

This feature is now officially rolling out to all WhatsApp users in the most recent update of WhatsApp on both Android and iOS versions. For several months, WhatsApp has been testing a feature that would allow users to link their account to secondary devices and continue to send and receive messages without the primary smartphone online.
