User Authentication of Applications on Third-Party Devices Via User Devices

One or more computer-readable non-transitory storage media embodying logic that is operable when executed to:

• receive, at a first computing device, an access token from a second computing device, the access token being generated by the second computing device for a specific software application executing on a specific computing device;
• store, by the first computing device, the access token;
• receive, at the first computing device, a request for the access token from a software application executing on a third computing device;
• verify, by the first computing device, whether the software application is the same as the specific software application and the third computing device is the same as the specific computing device for which the access token is generated;
• and
• send, by the first computing device, the access token to the third computing device only when the software application is the same as the specific software application and the third computing device is the same as the specific computing device for which the access token is generated.

A first computing device comprising:

• a memory comprising instructions executable by one or more processors;
• and
• the one or more processors coupled to the memory and operable to execute the instructions, the one or more processors being operable when executing the instructions to:
• receive an access token from a second computing device, the access token being generated by the second computing device for a specific software application executing on a specific computing device;
• store the access token;
• receive a request for the access token from a software application executing on a third computing device;
• verify whether the software application is the same as the specific software application and the third computing device is the same as the specific computing device for which the access token is generated;
• and
• send the access token to the third computing device only when the software application is the same as the specific software application and the third computing device is the same as the specific computing device for which the access token is generated.
