A computer-implemented technique can include receiving, at a first computing device including one or more processors, a request to share a document stored at a remote file storage server. The first computing device can establish a short range wireless communication link with a second computing device associated with an intended recipient of the document. The first computing device can obtain an identifier for the intended recipient from the second computing device using the short range wireless communication link. The first computing device can associate the identifier with the request and can then transmit the request to the remote file storage server. The request can cause the remote file storage server to provide the intended recipient with access to the document via the second computing device.
