Standards-Based Digital Credentials

Build privacy-preserving credential experiences with DiligenceID

Issue, verify, and govern digital credentials with standards-first protocols. Built on OpenID4VCI, OpenID4VP, and SD-JWT VC, DiligenceID replaces document copying and centralized data collection with minimal verified assertions.

Credentials remain with the holder

“Credentials remain with the holder. Applications ask questions of credentials through explicit verification policies. DiligenceID returns the minimum verified assertion required to make the application’s decision. Persistent identity data is the exception, not the default.”
