Multi-layer authentication

A computing device, comprising:

• one or more resource data stores;
• a first authentication service;
• and
• a second authentication service, wherein the first authentication service is configured to:
• receive a request from a requestor, the request including a request for access to one or more resources stored in the one or more resource data stores and access credentials of the requestor;
• determine that the access credentials satisfy a first authentication criteria;
• generate an authentication token;
• and
• forward at least a portion of the access credentials and the authentication token to the second authentication service;
• and
• wherein the second authentication service is configured to:
• receive at least a portion of the access credentials and the authentication token from the first authentication service;
• determine that the portion of the access credentials satisfies a second set of authentication criteria;
• and
• causes the requestor to have access to the requested resources.

A non-transient computer readable medium storing one or more sequences of instructions executable by one or more processors to perform a set of operations comprising:

• receiving, from a requestor, a request for access to one or more resources, the request including an access credential of the requestor;
• directing first information for the request to a first authentication service, the first information including at least a portion of the access credential;
• determining that the first information satisfies a first set of authentication criteria;
• generating, via the first authentication service, an authentication token;
• forwarding second information for the request to a second authentication service, the second information including at least a portion the access credential and the authentication token;
• determining, via the second authentication service, the request is not authorized based upon the second information and a second set of authentication criteria;
• and
• denying the access to the one or more resources.
