2. A system, comprising: at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the system to: receive, by a credentialing and access control system, identity and authentication information associated with at least one internal identity from at least one electronic identity provider that is external to the credentialing and access control system, based on permission granted by at least one user; generate at least a first physical resource token for permitting physical access to a first physical resource; associate the first physical resource token with the at least one internal identity; receive, by the credentialing and access control system and from the at least one user, identity and authentication information derived from the external identity provider that is associated with the at least one internal identity; receive, by the credentialing and access control system, an indication of interaction of the first physical resource token with the first physical resource; and grant access to the first physical resource.

The system of claim 2 wherein the received identity and authentication information is defined through an outside party electronic identity provider, wherein the credentialing and access control system receives the identity and authentication information associated with the at least one internal user based on permission granted by the at least one internal user, wherein the credentialing and access control system receives at least one condition from a first physical resource access owner for the at least one user to access it first physical resource, wherein the credentialing and access control system receives an indication that the at least one user has met the at least one condition.
