A computer-implemented method technique is presented. The technique can include selectively initiating, at a mobile computing device including one or more processors, communication between the mobile computing device and a public computing device. The technique can include transmitting, from the mobile computing device, authentication information to the public computing device. The authentication information can indicate access privileges to a private account associated with a user of the mobile computing device. The technique can include receiving, at the mobile computing device, an access inquiry from the public computing device. The access inquiry can indicate an inquiry as to whether the user wishes to login to the private account at the public computing device. The technique can also include transmitting, from the mobile computing device, an access response to the public computing device. The access response can cause the public computing device to provide the user with access to the private account.
