How to Add Constants to your wp-config.php file

In this tutorial, we will explain how to add constants to your wp-config.php file. While configuring the WP Mail SMTP plugin, Google credentials are added to the WordPress dashboard.

The plugin recommends adding code to your wp-config.php file to further protect your credentials.

Let us follow the steps:

1. Log in to your server through FTP or SSH.
2. Create and edit files through FTP or SSH.
3. Scroll down in this file to locate the following line-

   /* That’s all, stop editing! Happy blogging. */

4. Insert the following lines directly above this line.

   define( ‘WPMS_ON’, true );
   
   define( ‘WPMS_GMAIL_CLIENT_ID’, ‘********************.apps.googleusercontent.com’);
   
   define( ‘WPMS_GMAIL_CLIENT_SECRET’, ‘**********************’);
   
   define( ‘WPMS_MAILER’, ‘gmail’ );

   Note- The only portions you need to modify are “WPMS_GMAIL_CLIENT_ID” and “WPMS_GMAIL_CLIENT_SECRET”.

5. Save the file.

If you view the plugin page now, you will notice that your credentials are not accessible.

That is it!
