# User authentication

 * I have been working on a custom plugin for my organization. The plugin basically
   provides a medium for users to register and login.
 * I created a custom database table in the WordPress database to store information
   about registered users. However, when working the wp_authentication_username_password
   function, it failed to authenticate users whose information was stored in the
   custom table lablled wp-finusers. After researching I then realized that, the
   function was using the default users table to authenticate users.
 * The reason I wanted to use a custom table was to separate registered users and
   the WordPress Administrative users.
 * My question, is there a WordPress Filter that will enable the wp_authentication_username_password
   to using the custom table to perform user authentication or will I have to reconfigure
   the wp-core files to enable me to do so?

 * [@steve](https://wordpress.org/support/users/steve/), this what I have done after
   reading the link you provided.
 *     ```
       add_filter('wp_authenticate_user', 'custom_authentication',10 ,2);
   
       	function custom_authentication($emailAdd, $password) {
       		global $wpdb, $formErr;
   
       		if(1 > count($formErr->get_error_messages())){
       			$table = $wpdb->prefix.'finusers';
       			$sql = "SELECT * FROM $table WHERE email_address='$emailAdd' AND password='$password'";
       			$authenticate_user = $wpdb->query($sql);
   
       			if($authenticate_user!=0){
       				echo "Successful Authenticated user";
       			}else{
       				echo "Failed to authenticate user";
       			}
       		}
       	}
       ```
   
 * I still can get the user authenticated using this code, but is this the correct
   way to this? Any suggestions on adjusting this code would really be of great 
   help.
 * Thanks
