WhatsApp multi-device feature: Use one account on more than one phone

Finally, WhatsApp is enabling multi-device login for multiple phones.

Mark Zuckerberg announced the feature’s rollout on Facebook and Instagram.

“Starting today, you can log into the same WhatsApp account on up to four phones,” he said.

WhatsApp said that this feature will roll out to all users within the coming weeks.

Users were previously limited to using a single WhatsApp account across a single phone and multiple auxiliary desktop devices. Users’ messages will sync across devices, including other phones, with the new rollout. They can therefore access the app on other devices even if one is off.

WhatsApp, which has over 2 billion users worldwide, is one of the most popular messaging apps. However, until recently, multiphone support was unavailable due to the lack of full end-to-end encryption support for calls and chats. The company started testing cross-device compatibility with a small group of beta users in 2021. At the time, Meta (then known as Facebook) claimed to have invented a new technology that would allow messages to sync between devices while remaining encrypted end-to-end.

Other competitors, such as Telegram and Messenger, provided multidevice message sync but did not support end-to-end encryption. WhatsApp began making multidevice features available to everyone in 2022. However, it did not support multiple phones.

WhatsApp is also rolling out a new way to link devices using a one-time code.

“You can now get a one-time-use code by entering your mobile number on WhatsApp Web, which you can use to link devices instead of scanning the QR code on your mobile phone.” “We’ll make this feature available for more linked devices in the future,” the company said in a blog post.
