SSO (Single Sign-On) with WordPress | WordPress interface programming with onehundred.digital

An SSO (Single Sign-On) with WordPress allows users to log in once to a central identity source and then access multiple WordPress websites without having to log in again to each individual website. This makes it easier to manage user accounts in companies and improves the user experience.

To be able to use the single sign-on function in WordPress, you either need to use a special plugin or develop an interface that establishes a connection to an SSO platform or an identity provider (IdP). Some popular SSO plugins for WordPress include “Simple SSO” or “WP OAuth Server”.

The integration of the single sign-on solution in WordPress with the help of a plugin is divided into the following points:

1. Based on your company’s requirements, we evaluate the available solutions and select the plugin that best suits your company.
2. To connect the plugin to the identity provider or your SSO platform, the required registration information must be set up. Depending on the provider, the setup of your WordPress site as a client application differs, follow the instructions of your provider here. The services most used by companies are “Auth0”, “Okta” or “Azure Active Directory”.
3. After installing the plugin and setting up the WordPress website as a client application, the plugin is configured. The plugin settings are supplemented with the login information of your provider. The parameters to be added differ depending on the plugin and identity provider. The parameters required for the exchange of information between WordPress and the SSO provider include a client ID, a client secret, an authorization URL or other parameters.
4. Once the basic configuration is complete, the login option is set up. Here you decide whether to log in to the standard WordPress login screen or directly to the SSO provider.
5. If desired by the customer, the login screen can be customized to better match the corporate identity of the company.
6. Once the configuration has been completed, the functionality of the solution is tested. To do this, the user logs out of the company’s WordPress website and attempts to log in via the SSO provider or, alternatively, the WordPress selection screen. The login process is then checked for the correctness of the SSO function and access authorization to the correct resources.

It is important to note that the exact steps may vary depending on the SSO plugin and SSO provider you are using. It is recommended to carefully read and follow the documentation of the selected plugin as well as the instructions of the SSO provider in order to set up the SSO correctly.
