Exostar ProviderPass is an identity verification and digital signing solution designed for healthcare providers to comply with DEA regulations for Electronic Prescribing of Controlled Substances (EPCS). The product is certified at Identity Assurance Level 2 (IAL2) by the Kantara Initiative, enabling healthcare organizations to meet federal identity proofing standards required for EPCS. Key functional areas include: **Identity Proofing:** Providers are verified through IAL2-certified processes. An optional live, webcam-based identity proofing session with an Exostar specialist is available for users who prefer guided verification. **Two-Factor Authentication (2FA):** Access to prescribing workflows is secured via two-factor authentication, restricting digital signing to authorized personnel only. **PKI-Based Digital Signing:** Prescriptions are signed using Public Key Infrastructure (PKI) technology, producing DEA-compliant digital signatures that ensure tamper-proof authenticity. **EHR Integration:** ProviderPass integrates natively with existing Electronic Health Record (EHR) systems, allowing providers to maintain existing workflows while adding EPCS compliance functionality. The product is reported to be used by over 100,000 users. A case study documents deployment with Juno Health, where over 1,200 healthcare providers use ProviderPass to prescribe controlled substances through the Juno Health EHR module.
