A Credential in the digital realm is a structure which contains, at a minimum, a secret value which can be used in Authentication of a Subject.
- The original digital Credential was just a shared secret, usually called a Password.
- More secure Credentials keep private keys which are used to build an Identity Token which can include anti-replay elements, that (with User Consent) is sent to a requester.
- A Certificate binds a credential to an Identifier of its owner as well as (potentially) other Attributes.
- Typically there is also a binding to some sort of real-world credential, usually a piece of paper with a seal.
