US Patent 11792021 Resiliency architecture for identity provisioning and verification

Identity access and management (“IAM”) systems with resiliency features and methods related to the same are provided. Two or more identity provider (“IDP”) systems each have a matching copy of user authentication data for users authorized to access the system of an organization. An identity proxy is interposed between user systems and each of the two or more IDP system. The identity proxy routes authentication requests, challenges, and responses between the user systems and the IDP systems based on availability.
