Credential Format Explorer

Browse the three credential formats supported by the Digital Credentials API — mDoc/ISO 18013-5, W3C VC JWT, and SD-JWT. Select claims, see privacy impact, and generate the navigator.credentials.get() call for each format.

checking Digital Credentials API…

The Digital Credentials API lets websites request specific claims from a wallet app (driving licence, passport, etc.) without receiving the full document. Only the requested claims are disclosed — selective disclosure prevents oversharing. Each format has different disclosure mechanisms.

Format

mDoc (ISO 18013-5)

VC JWT (W3C)

SD-JWT

mDoc: ISO 18013-5 standard for mobile driving licences. Claims organised in namespaces. CBOR-encoded. Used by DMVs and national ID programmes. Selective disclosure via intentToRetain flag per element.

Select claims to request:

VC JWT: W3C Verifiable Credentials encoded as a JSON Web Token. All claims in a single signed blob — no per-claim disclosure (use SD-JWT for that). Better for asserting credentials from issuers with existing PKI.

SD-JWT: Selective Disclosure JWT. Claims are individually hash-committed; the holder reveals only the selected ones. The best format for privacy-preserving presentations.
