This document is a request for proposals from New York eHealth Collaborative (NYeC) seeking a vendor to implement a statewide two-factor authentication solution. The solution must comply with NIST SP 800-63-1 Level 3 requirements and balance security, usability, and adoption. It will enable secure access to patient health information across the Statewide Health Information Network for New York (SHIN-NY) by users accessing via regional health information organizations (RHIOs), electronic health records (EHRs), and other systems. The statewide solution will provide identity and access management services including identity proofing, credential issuance, and token management to authenticate users before granting access to SHIN-NY data and related uses
