  • OpenID allows you to identify yourself with one or more URLs. 

     

    Each URL is vouched for by a particular OpenID service provider. It is up to the websites consuming OpenID logins (these websites are called Relying Parties (RP) in the lingo) to determine how much they trust each service provider when assigning authorisation privileges based on the OpenID login.
  • OAuth provides a way to grant authorisation (access permission) to your data on some website to a third website, without needing to provide this third website with your authentication information for the original website. It provides an authentication token that the third-party can use (and only that third-party).
