The term, in context
AI-assisted draft · approved dataset
WebAuthn Level 3 is the third revision of the Web Authentication (WebAuthn) specification, the browser API through which sites register and use public-key credentials such as passkeys in place of passwords. It refines the earlier revisions with additions covering creation hints, richer client capability and extension queries, and clarified cross-origin behavior, while remaining compatible with authenticators built for the specification's previous levels.
