Logo of WebFinger

WebFinger is a protocol specified by the Internet Engineering Task Force IETF that allows for discovery of information about people and things identified by a URI.[1] Information about a person might be discovered via an "acct:" URI, for example, which is a URI that looks like an email address.

WebFinger is specified as the discovery protocol for OpenID Connect,[2] which is a protocol that allows one to more easily log in to various sites on the Internet.[3]

The WebFinger protocol is used by the federated social networks StatusNet[4] and Diaspora[5] to discover users on federated nodes and pods as well as the remoteStorage protocol.[6]

As a historical note, the name "WebFinger" is derived from the old ARPANET Finger protocol, but is a very different protocol designed for HTTP.[7]
