WhatsApp is continuing to upgrade its platform with a stronger focus on security for linked devices, as more users now rely on multiple devices for communication.
The company has expanded its chat lock feature to cover linked devices, adding an extra layer of privacy and control.
Previously, chat lock was only available on a user’s primary device, leaving private conversations potentially accessible on companion devices. With the new update, users will be able to secure their chats on linked devices using a secret passcode, ensuring that sensitive messages remain protected across all connected devices.
As the use of linked devices grows, WhatsApp is also addressing the risks that come with increased flexibility. While users can already switch between phones, tablets, and desktops seamlessly, unattended or shared devices can pose privacy concerns.
To improve oversight, WhatsApp is developing a real-time monitoring system for linked devices. This feature will allow users to view active sessions more clearly and receive alerts when multiple devices are being used at the same time.
For example, if a linked session such as WhatsApp Web becomes active while a user is also using the app on their phone, an alert will be sent to the primary device. This will help users quickly detect unusual or unauthorized activity and take action, such as logging out of the unknown session.
The notifications will only trigger when more than one device is active simultaneously, preventing unnecessary alerts during normal single-device use. The primary smartphone will remain the central hub for all security notifications and account controls.
Overall, these upcoming features highlight WhatsApp’s continued push toward stronger privacy protection. By combining chat locking for linked devices with real-time activity alerts, the platform aims to give users better control over their accounts and a safer messaging experience across multiple devices.
