Single sign-on through customer authentication systems

A system, comprising:

• a memory;
• and
• a processor coupled to the memory, the processor configured to perform operations comprising:
• sending, by a service provider, an authentication request from a user device to an identity provider that is a web service accessed by the user device, wherein the authentication request indicates the identity provider and includes a user identifier;
• validating an authentication token, received from the identity provider responsive to the authentication request, against internal configuration information of the service provider;
• and
• generating, by the service provider, an identity element for the user device that enables the user device to access a resource by performing a hashing operation utilizing, as inputs, the validated authentication token, the user identifier, and the internal configuration information, wherein the internal configuration information used in the hashing includes an entity identifier of an entity, and wherein the entity corresponds to an organization of users.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a device, cause the one or more processors to perform operations comprising:

• sending, by a service provider, an authentication request from a user device to an identity provider that is a web service accessed by the user device, wherein the authentication request indicates the identity provider and includes a user identifier;
• validating an authentication token, received from the identity provider responsive to the authentication request, against internal configuration information of the service provider;
• and
• generating, by the service provider, an identity element for the user device that enables the user device to access a resource by performing a hashing operation utilizing, as inputs, the validated authentication token, the user identifier, and the internal configuration information, wherein the internal configuration information used in the hashing includes an entity identifier of an entity, and wherein the entity corresponds to an organization of users.
