WhatsApp-linked device security may soon improve for Android users, as the platform develops a feature that would let people monitor activity across connected devices in real time. The update aims to give users better visibility into account activity as more people rely on WhatsApp across phones, computers, and other linked devices.
WhatsApp is building the feature into the Android beta 2.26.15.6 update. It would send automatic alerts when another linked device becomes active at the same time as the primary device.
Right now, users can check active sessions through the Linked Devices screen. However, that process requires manual review, which makes it easier to miss suspicious activity.
The new feature would change that by sending notifications directly to the primary device whenever concurrent usage appears. For example, if someone keeps WhatsApp Web open on a computer while also using the app on their phone, WhatsApp would issue an alert.
Why the New Alerts Matter
This update could make account monitoring faster and more practical. Instead of repeatedly checking settings, users would receive immediate notice when another linked device becomes active.
That matters because quicker alerts can help users spot possible unauthorised access earlier. At the same time, WhatsApp plans to limit these notifications to relevant cases, thereby reducing unnecessary interruptions.
The upcoming change follows an earlier WhatsApp beta for Android 2.24.11.9 update that introduced chat locks on linked devices. That feature lets users protect conversations with a passcode from companion devices.

Previously, locked chats only worked on the primary device. Now, WhatsApp appears to be extending more security controls across linked devices through a secret code system.
The feature is still under development, so it is not yet widely available. WhatsApp expects to release it in a future update, first to select users and later to a broader audience.
That phased rollout suggests WhatsApp is treating linked-device security as an ongoing part of its wider privacy strategy.
