Annotated NIST SP 800-63C-4 (federation and assertions)
We've annotated volume C, Federation and Assertions, of NIST’s Digital Identity Guidelines series (SP 800-63). The annotations specify the NIST definition of each term the first time a term appears. The annotations also indicate the recommendations, definitions, and other information that we feel are most important.
