Step-by-step explanation:
The subject of this question is Computers and Technology. This question is asking about a feature that can be enabled for a specified device to help resolve communication issues with an online application. However, this feature poses a security risk and should be used with caution.
One example of such a feature is **remote access**. Remote access allows a user to connect to and control a device from a different location.
