Trusted login of user accounts

A non-transitory, computer-readable medium storing one or more instructions executable by a first server that provides a service page within a target application to perform operations comprising:

• receiving, from a second server that serves an originating application;
• a temporary trusted login token request for accessing the service page;
• generating a temporary trusted login token based on the temporary trusted login token request, wherein the temporary trusted login token includes a service authorization that identifies one or more service pages that can be accessed through temporary trusted login, the temporary trusted login token comprising a first mapping relationship between one or more service identifications corresponding to one or more allowed service pales and the temporary trusted login token, and further comprising a second mapping relationship between a current trusted login identification issued by the first server and the temporary trusted login token, wherein the first mapping relationship and the second mapping relationship are separate mapping relationships;
• sending the temporary trusted login token to the originating application using the second server;
• receiving a service page access request for accessing the service page generated based on the temporary trusted login token;
• identifying the temporary trusted login token including the service authorization from the service page access request;
• determining if the service page is included in the one or more service pages that are identified by the service authorization;
• and
• allowing trusted login to the service page from the originating application if the service page is included in the one or more service pages, the allowing of the trusted login comprising displaying the service page in the originating application without redirecting to the target application for the display of the service page.

A computer-implemented system, comprising:

• one or more computers comprising a first server that provides a service page within a target application;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving, from a second server that serves an originating application, a temporary trusted login token request for accessing the service page;
• generating a temporary trusted login token based on the temporary trusted login token request, wherein the temporary trusted login token includes a service authorization that identifies one or more service pages that can be accessed through temporary trusted login, the temporary trusted login token comprising a first mapping relationship between one or more service identifications corresponding to one or more allowed service pages and the temporary trusted login token, and further comprising a second mapping relationship between a current trusted login identification issued by the first server and the temporary trusted login token, wherein the first mapping relationship and the second mapping relationship are separate mapping relationships;
• sending the temporary trusted login token to the originating application using the second server;
• receiving a service page access request or accessing the service page generated based on the temporary trusted login token;
• identifying the temporary trusted login token including the service authorization from the service page access request;
• determining if the service page is included in the one or more service pages that are identified by the service authorization;
• and
• allowing trusted login to the service page from the originating application if the service page is included in the one or more service pages, the allowing of the trusted login comprising displaying the service page in the originating application without redirecting to the target application for the display of the service page.
