OpenID is a shared identity service, which allows internet users to log on to many different web sites using a single digital identity, eliminating the need for a different user name and password for each site. OpenID is a decentralized, free and open standard that lets users control the amount of personal information they provide.
By using FUPEI, web users do not need to remember traditional authentication tokens such as username and password. Instead, they only need to be remembering FUPEI login information.
A relying party web site (e.g. example.website.com) displays an OpenID login form somewhere on the page. Unlike a typical login form with fields for the user name and password, the OpenID login form has only one field - for the OpenID identifier, typically along with a small OpenID logo 
. This form is connected to an implementation of an OpenID client library.
A member FUPEI typically will have an OpenID identifier (http://id.fupei.com/FUPEI-ID). The user visits the relying party web site and types her OpenID identifier in the OpenID login form.
