Methods, devices, and computer program products for authenticating a peripheral device are provided in embodiments of the present disclosure. In one method, a peripheral device sends, to an edge device, a first authentication request for at least the peripheral device to use resources of the edge device, the first authentication request comprising at least a first identifier associated with the peripheral device and location information of the peripheral device. Then, the peripheral device receives an authentication success or failure indication from the edge device. In this way, effective authentication of a peripheral device can be realized with a less complicated authentication process, so that the security of access of the peripheral device to a virtual desktop can be improved while ensuring good user experience.
