Digital Identity Guidelines

Digital identity is only as strong as the way it’s authenticated—and NIST SP 800-63B-4 provides the updated blueprint. This guidance focuses on secure authentication mechanisms such as multi-factor authentication, biometrics, and passwordless strategies. It also addresses lifecycle management, detailing how credentials should be issued, maintained, and revoked to prevent misuse. As cyber threats evolve, these standards aim to help agencies balance usability with rigorous security.
