<p>XLogin enhances the WordPress login page (usually wp-login.php) to<br />
allow users to authenticate with the following external services:</p>
<ul>
<li>Facebook Login</li>
<li>Google Sign-In</li>
<li>Yahoo! OAuth</li>
</ul>
<p>These services can be enabled or disabled individually. XLogin adds a<br />
button to the WordPress login page for each enabled service. Clicking<br />
the button sends the browser to the corresponding external service<br />
where the user can authorize the WordPress site to access their<br />
information. Having been granted access to, for example, the Facebook<br />
public profile of a user, XLogin retrieves their email address to<br />
find a matching WordPress user to complete the login process.</p>
<p>XLogin also maintains a list of external aliases. They are additional<br />
email addresses for mapping to WordPress users. Some scenarios where<br />
external aliases can be handy include:</p>
<ol>
<li>
<p>A user’s email address in his WordPress profile is not used in any<br />
of the external services. For example, a corporate WordPress site<br />
may mandate the use of company email addresses in user<br />
profiles. If a user has for example his Gmail address in the<br />
external alias list, they can still nevertheless sign in Google.</p>
</li>
<li>
<p>A WordPress user account is shared by a group of actual<br />
users. With XLogin it is not necessary to have the users share a<br />
single password. Instead just register their email addresses (as<br />
known by the external services) as external aliases; it becomes a<br />
simple matter to add and remove user.</p>
</li>
</ol>
<p>XLogin has the option to restrict an external service to only users with<br />
external aliases. This allows tight control on who can use external<br />
services to login.</p>
<p>A user’s profile in WordPress and in the external service may be<br />
different.  Email address is one, and display name (or its component<br />
family and given names) is another. XLogin offers the option to import<br />
the external profile information into the current session. The imported<br />
display name will be tagged with the external service name. For<br />
example, if a user has display name ‘John Doe’ in WordPress, but is<br />
known as ‘Johnny D’ in his Facebook account, then he would be<br />
displayed as ‘Johnny D (Facebook)’ (instead of ‘John Doe’) in his<br />
WordPress session when he logs in with Facebook.</p>
<p>Finally XLogin has the notion of ‘guest’ user. When an email address<br />
provided by an external service does not correspond to a specific<br />
WordPress user, XLogin will proceed with a guest WordPress user<br />
configured for the service. There are plugins that control access to<br />
content based on user roles; a site can combine such with XLogin to<br />
control what is visible to guests. Note that guest WordPress users<br />
should have minimal privileges. XLogin has safeguards to ensure, for<br />
example, that a guest cannot edit posts. It also filters out guest’s<br />
permission to access the dashboard or to update their own profile.</p>
