In this step, you will add the parseable arrays of variables that you exported before, as a named constant to your WordPress website’s wp-config.php file.

To update your site’s wp-config.php, proceeds as follows.

• Retrieve a copy of your site’s wp-config.php, for example with your favorite FTP client or open it in edit-mode with a file manager of your choice.
• Locate the line that reads /* That’s all, stop editing! Happy publishing. */.
• Add a new line to define the new named constant WPO_IDPS_1 as follows.

---

Please note that as soon as you added the named constant to your site’s wp-config.php file, WPO365 will detect it and use it to “read” the IdPs configuration .

/* That's all, stop editing! Happy publishing. */

The name of constant is by default WPO_IDPS_1. The number (in this case “1”) refers to the blog ID of the current site. If you don’t run WordPress Multisite and if you haven’t configured BLOG_ID_CURRENT_SITE then the blog ID of the current site defaults to 1.

• Continue by saving your changes and update your website’s wp-config.php by uploading the file – for example – using your favorite FTP client.
• As a last step, you may want to obfuscate the Azure AD / IdP secrets by clicking the corresponding option on the plugin’s Single Sign-on page (or Mail configuration page when you’re using the WPO365 | MICROSOFT GRAPH MAILER instead of WPO365 | LOGIN plugin). This will replace the (secret) IdP values with placeholder values, as shown below.
