In one aspect, a first device includes at least one processor and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to determine that an application stored at the first device is programmed to communicate with a second device. The instructions are then executable to, based on the determination, present an indication at the first device of a current location of the second device and/or a domain name associated with the second device. The instructions are also executable to receive user input approving the application to communicate with the second device subsequent to presenting the indication, and then to permit the application to communicate with the second device via the first device responsive to the user input.
