Security is an essential element when you are operating online. WP Mail SMTP plugin follows the best security practices and it also offers various security options to its users. For example, instead of adding the credentials directly to the WordPress database, the plugin uses tokens or API keys to protect your credentials. Similarly, while using “Other SMTP” providers, it gives you the option to enter a password inside the WordPress wp-config.php master configuration file so it does not get saved inside the database.    


Just like any good plugin, WP Mail SMTP also maintains well-structured documentation for its users. This documentation does not only help the users to use the plugin properly but also helps the developers to check for compatibility issues and to troubleshoot other technical problems.
