Device Authentication Sharing

A method comprising:

• detecting, at a gateway of a local network, authentication of a user device for communication with a first local device, wherein the first local device is in communication with the gateway via the local network;
• sending, by the gateway and to a second local device operating on the local network, an authentication notice that indicates that the user device has authenticated for communication with the first local device;
• receiving, by the gateway and from the second local device, a share request requesting sharing of the authentication of the user device with the second local device;
• obtaining, by the gateway, a token that defines a permission associated with the authentication, a time limit associated with the authentication, and a location limit associated with the authentication;
• and
• triggering delivery of the token to the second local device to share the authentication of the user device with the second local device, whereby the second local device communicates with the user device via a connection supported by the gateway.

A computer storage medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

• detecting, at a gateway of a local network, authentication of a user device for communication with a first local device, wherein the first local device is in communication with the gateway via the local network;
• sending, by the gateway and to a second local device operating on the local network, an authentication notice that indicates that the user device has authenticated for communication with the first local device;
• receiving, by the gateway and from the second local device, a share request requesting sharing of the authentication of the user device with the second local device;
• obtaining, by the gateway, a token that defines a permission associated with the authentication, a time limit associated with the authentication, and a location limit associated with the authentication;
• and
• triggering delivery of the token to the second local device to share the authentication of the user device with the second local device, whereby the second local device communicates with the user device via a connection supported by the gateway.
