Pairing with companion device

A display system comprising:

• a head mountable display;
• memory storing executable instructions;
• and
• one or more processors in communication with the memory and the display, the one or more processors programmed by the executable instructions to perform operations comprising:
• receiving a request to authenticate a connection between the display system and a companion device;
• responsive to receiving the request to form the connection, determining first data to be used in authenticating the connection between the display system and the companion device, wherein the first data is based at least partly on biometric data that is associated with a user of the display system;
• transmitting the first data to an authentication device that is configured to authenticate the connection based at least in part on comparing the first data to second data that is received by the authentication device from the companion device, the second data based at least partly on the biometric data;
• receiving, from the authentication device, a confirmation of a successful authentication of the connection, wherein the successful authentication is determined by the authentication device based at least partly on determining a match between the first data and the second data;
• and
• in response to receiving the confirmation of successful authentication of the connection,
• permitting bi-directional communication of data between the companion device and the display system using the connection, and
• presenting, through the display, a notification to the user of the display system that the connection has been authenticated.
