WhatsApp is testing a feature that could notify users if their account is being used on another device at the same time. The move is aimed at tightening everyday security, especially as more people rely on the platform across laptops and shared systems.
WhatsApp’s multi-device feature has made life easier for users who switch between phone and desktop during the day. This ease comes with a trade-off.
Many users log in on office computers or shared laptops and forget to log out, often without realising that their chats remain accessible. Such gaps rarely feel urgent until personal information is misused. The planned alert system addresses this issue.
Instead of expecting users to keep checking their linked devices, WhatsApp plans to step in with a timely warning. The approach feels less about adding another setting and more about closing a routine loophole that has existed for years.
The feature will most likely monitor the user's activities in all connected devices and notify the user when another device is activated while they are using their primary phone.
The notification will occur instantly and allow users to check and log out ongoing sessions, preventing any suspicious activity.
Notifications will only appear at times of concurrent access, meaning they will not be redundant. Users also have the choice to customize alerts.

For regular people, the feature will serve as a passive measure to protect privacy. Grouped software in offices, houses, or outdoor venues can create instances of involuntary contact, and without instant notifications, these incidents can be difficult to detect.
Over the past few years, WhatsApp has incorporated many features that help protect users' privacy, but the latest addition sets itself apart with its ease of use. It does not require any behavioural changes from the user; it only needs to notify them about the ongoing activities. However, the company has not commented on the roll-out date yet.
