A device may receive an indication to generate a link associated with accessing a message. The message may be intended for a shared device identifier of a receiver device identified by a receiver device identifier, where the shared device identifier is shared by multiple receiver devices. The device may store information associating the message with the receiver device identifier. The device may generate the link using information associated with the message. The device may provide the link to the receiver device after generating the link. The device may receive a request, from a requesting device, to access the message, the request including a device identifier associated with the requesting device. The device may selectively permit or prevent access to the message, by the requesting device, based on the stored information and the device identifier associated with the requesting device.
