In securing your WordPress, the 1st thing that you need to change is the admin username. The default value for this is “admin” and you need to change it to something else. I used to teach changing this in the database but this is a little complicated for those who do not know anything about MySQL or databases.
I created the WordPress Change Admin Username Plugin to solve this problem, all you need is to install the plugin and change the admin username in the WordPress Dashboard. The WordPress Plugin has a simple functionality but very useful.
