Linked Devices is a feature commonly found in messaging and communication applications that allows users to access the same account from multiple devices simultaneously. This enables seamless synchronization of messages, contacts, and settings across smartphones, tablets, and computers. While convenient, linking devices can introduce security risks if not properly managed, such as unauthorized access or data breaches. To mitigate these risks, many platforms implement authentication mechanisms, device management controls, and session monitoring. Regularly reviewing and managing linked devices is essential to maintaining account security and ensuring that only trusted devices have access.
