Conserving computing resources via application-level authentication of action execution requests

A computer-implemented method comprising:

• communicatively coupling an intermediary application programming interface (API) integration layer between a network and a computing system;
• receiving, by a processor of the computing system, from a client device over a channel of one or more channels and via a web browser connected to the intermediary API integration layer through the network and employing a cryptographic protocol, a request to execute an action at an application of interest residing on the computing system, the request including compiled multifactor client authentication information that is unique to the application of interest;
• authenticating the client device as being permitted to make the request in part by executing, by the processor, a code-based authentication module of the application of interest to:
• compare, at the application of interest, a client digital certificate of the compiled multifactor client authentication information with a set of previously validated digital certificates that is stored in a digital certificate store of a memory of the computing system and accessible by the authentication module,
• compare, at the application of interest, client login credentials of the compiled multifactor client authentication information with a set of previously validated login credentials that is stored in a login credentials store of the memory of the computing system and accessible by the authentication module,
• validate the client digital certificate when the client digital certificate matches a digital certificate of the set of previously validated digital certificates stored in the digital certificate store, and
• validate the client login credentials when the client login credentials match login credentials of the set of previously validated login credentials stored in the login credentials store;
• and
• in response to authenticating the client device by the code-based authentication module of the computing system, executing the action by the application of interest.

A non-transitory computer-readable medium comprising instructions that are executable by a processor of a computing system for causing the processor to perform operations comprising:

• receiving, from a client device, at an application of interest residing on the computing system, over a channel of one or more channels and via a web browser connected to an intermediary API integration layer communicatively coupled between a network and the computing system and employing a cryptographic protocol, a request to execute an action at the application of interest, the request including compiled multifactor client authentication information that is unique to the application of interest;
• authenticating the client device as being permitted to make the request in part by executing a code-based authentication module of the application of interest to:
• compare, at the application of interest, a client digital certificate of the compiled multifactor client authentication information with a set of previously validated digital certificates that is stored in a digital certificate store of a memory of the computing system and accessible by the authentication module,
• compare, at the application of interest, client login credentials of the compiled multifactor client authentication information with a set of previously validated login credentials that is stored in a login credentials store of the memory of the computing system and accessible by the authentication module,
• validate the client digital certificate when the client digital certificate matches a digital certificate of the set of previously validated digital certificates stored in the digital certificate store, and
• validate the client login credentials when the client login credentials match login credentials of the set of previously validated login credentials stored in the login credentials store;
• and
• in response to authenticating the client device by the code-based authentication module of the computing system, executing the action by the application of interest.
