Overview#

OpenID is an open standard from the OpenID Foundation that allows users to be authenticated by certain co-operating sites (known as Relying Parties or RP) using a third party service, eliminating the need for web-masters to provide their own ad hoc systems and allowing users to consolidate their digital identities.

Users may create accounts with their preferred OpenID identity providers, and then use those accounts as the basis for signing on to any website which accepts OpenID authentication.

The OpenID standard provides a framework for the communication that must take place between the identity provider (IDP) and the OpenID acceptor Relying Party.

An extension to the standard (the OpenID Attribute Exchange) facilitates the transfer of user attributes, such as name and gender, from the OpenID Identity Provider (IDP) to the relying party (each relying party may request a different set of attributes, depending on its requirements).

The OpenID protocol does not rely on a central authority to authenticate a user's Digital Identity. Moreover, neither services nor the OpenID standard may mandate a specific means by which to authenticate users, allowing for approaches ranging from the common (such as passwords) to the novel (such as Smart Cards or biometrics).

The term OpenID may also refer to an identifier as specified in the OpenID standard; these identifiers take the form of a unique URI, and are managed by some 'OpenID provider' that handles authentication.
