Title: XLogin Author: Patrick Lai Published: March 21, 2020 Last modified: June 5, 2021 --- Search plugins This plugin **hasn’t been tested with the latest 3 major releases of WordPress**. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://ps.w.org/xlogin/assets/icon-256x256.png?rev=2266781) # XLogin By [Patrick Lai](https://profiles.wordpress.org/scoop082110/) [Download](https://downloads.wordpress.org/plugin/xlogin.1.1.3.zip) * [Details](https://pcd.wordpress.org/plugins/xlogin/#description) * [Reviews](https://pcd.wordpress.org/plugins/xlogin/#reviews) * [Installation](https://pcd.wordpress.org/plugins/xlogin/#installation) * [Development](https://pcd.wordpress.org/plugins/xlogin/#developers) [Support](https://wordpress.org/support/plugin/xlogin/) ## Description XLogin enhances the WordPress login page (usually wp-login.php) to allow users to authenticate with the following external services: * Facebook Login * Google Sign-In * Yahoo! OAuth These services can be enabled or disabled individually. XLogin adds a button to the WordPress login page for each enabled service. Clicking the button sends the browser to the corresponding external service where the user can authorize the WordPress site to access their information. Having been granted access to, for example, the Facebook public profile of a user, XLogin retrieves their email address to find a matching WordPress user to complete the login process. XLogin also maintains a list of external aliases. They are additional email addresses for mapping to WordPress users. Some scenarios where external aliases can be handy include: 1. A user’s email address in his WordPress profile is not used in any of the external services. For example, a corporate WordPress site may mandate the use of company email addresses in user profiles. If a user has for example his Gmail address in the external alias list, they can still nevertheless sign in Google. 2. A WordPress user account is shared by a group of actual users. With XLogin it is not necessary to have the users share a single password. Instead just register their email addresses (as known by the external services) as external aliases; it becomes a simple matter to add and remove user. XLogin has the option to restrict an external service to only users with external aliases. This allows tight control on who can use external services to login. A user’s profile in WordPress and in the external service may be different. Email address is one, and display name (or its component family and given names) is another. XLogin offers the option to import the external profile information into the current session. The imported display name will be tagged with the external service name. For example, if a user has display name ‘John Doe’ in WordPress, but is known as‘ Johnny D’ in his Facebook account, then he would be displayed as ‘Johnny D (Facebook)’( instead of ‘John Doe’) in his WordPress session when he logs in with Facebook. Finally XLogin has the notion of ‘guest’ user. When an email address provided by an external service does not correspond to a specific WordPress user, XLogin will proceed with a guest WordPress user configured for the service. There are plugins that control access to content based on user roles; a site can combine such with XLogin to control what is visible to guests. Note that guest WordPress users should have minimal privileges. XLogin has safeguards to ensure, for example, that a guest cannot edit posts. It also filters out guest’s permission to access the dashboard or to update their own profile. ## Screenshots * [[ * WordPress login page with buttons for external logins. * [[ * Display name of user imported from external service, e.g. Facebook. * [[ * XLogin settings page. * [[ * Configuration of OAuth2 based external service, e.g. Google. Note the redirect URI that should be added to the OAuth2 client configuration in the external service. * [[ * Add or update an external alias. * [[ * Upload CSV file of external aliases. ## Installation 1. Upload the plugin files to the ‘…/wp-content/plugins/xlogin’ directory, or install the plugin through the ‘Plugin’s screen in WordPress. 2. Activate the plugin. 3. Configure external services for login on the Settings->XLogin page. 4. * Enter configuration data for the external service. For an OAuth2 based service, that means client ID and client secret. Note that the redirect URI for OAuth2 is displayed here. * Set per-service options: - Restrict to users with external aliases. - Import profile information (email address and name) from external service into session. * Enable external services. 5. Maintain external aliases on the Settings->XLogin page. 6. * Aliases may be added/updated/deleted one at a time. * Filters may be applied to the list of aliases displayed. * Multiple aliases may be uploaded in a CSV file. Each line in the file contains an email address and a WordPress user name, separated by comma. If WordPress permalinks are ‘plain’, one may need to configure the web server to route callbacks from external service to WordPress index.php script. For Apache that would mean rewrite rules in .htaccess like theses: `RewriteEngine On RewriteRule wp-content/plugins/xlogin/callback/ index.php [L] ## FAQ ### Does this work with WordPress version X? This plugin was originally developed with WordPress 5.3. It has been tested to various extent up to 5.7. ### Does this work with PHP 5.x? No. This plugin uses various PHP 7.x features. Backporting to PHP 5.x should not be difficult however. ### How do I obtain client ID and secret to configure an OAuth2 based external service( e.g. Facebook)? Here are some pointers: * Google. A project must first be set up. OAuth2 clients are managed on the [API credentials](https://console.developers.google.com/apis/credentials) page. Use an existing or create a new OAuth client, of ‘web application’ type. * Facebook. An ‘app’ must first be set up. Use the ‘App ID’ and ‘App Secret’ from the its basic settings page for client ID and secret respectively. Add Facebook Login to the product list of the app, and configures the redirect URI there. * Yahoo. A Yahoo app corresponds to an OAuth2 client. Make sure your app has email and profile permissions for OpenID Connect. ### A user tries to login with Google, but gets sent back to the WordPress login page with a “Google user not recognized” error. What does this mean? XLogin uses the email address provided by Google (or whatever external service) to map to a WordPress user. Check the following: * Is the email address registered as an external alias in XLogin? * Does email address belong to a WordPress user profile? If so, make sure the external service is not configured as ‘restricted’. ### The “*XYZ* user not recognized” error is confusing. Can the login page show only external login buttons that are applicable to the user? Generally XLogin may not know anything about the user until the end of authentication/ authorization with the external service, so it would be a challenge. ### How does XLogin override the email and display name of a user? This is rather technical, but is important for ongoing maintenance of the plugin. This answer is intended for PHP developers working with WordPress. WordPress keeps track of the user of the current request in various PHP global variables. XLogin installs a callback for the `set_current_user` action to inject profile information from external service into them. The action name and the global data structures may be specific to WordPress versions; the file `init.php` and the PHP method XLogin::importXUser() are expected to be modified to support more WordPress versions. ### Can XLogin be used for new user registration? This is not supported currently. ### Can XLogin support other external services? XLogin uses the [OAuth 2 Client](https://oauth2-client.thephpleague.com/) from The League of Extraordinary Packages. It should be straightforward to add an additional OAuth2 based login service as long as a compatible _provider_ is available. See the [list of providers](https://oauth2-client.thephpleague.com/providers/league/). ## Reviews There are no reviews for this plugin. ## Contributors & Developers “XLogin” is open source software.
