Digital Identity Guidelines

Verifying identity in the digital age is more than a checkbox—it’s a foundational element of trust. NIST’s updated 800-63A-4 offers detailed guidance for federal agencies and organizations on secure, privacy-respecting identity proofing. It introduces flexible approaches that account for risk, usability, and equity while strengthening protections against fraud and impersonation. With emerging technologies and threats, these standards help align security with accessibility in digital services.
