If your username for logging in to your WordPress dashboard is “admin”, then you should change it straight away. With the recent brute force hack attempts being experienced on WordPress sites, it makes it a lot easier for someone to gain access to your site if they already know the username. By using the default “admin” username, the hacker already knows half the equation of the username/password combination. Guessing the password isn’t all that difficult to do if given the oppurtunity to try thousands of times running through a dictionary of words. By simply changing your username to something other than “admin” you have just made your WordPress site far more secure.
If you have not changed the username from the default “admin” yet, this is the first thing that should be done after installing WordPress.
1) Login to your WordPress dashboard as the admin user.
2) Go to Users > Add New
3) Fill out the details for the new admin user. Choose a username that is not obvious to the public. Use a strong password. Make sure you select “Administrator” as the role of the new user.
4) Log out of the dashboard, and log back in using the new account you just created.
5) Go to Users, and view the list of users. Hover over the old “admin” account and click delete.
6) You will then be asked what you want to do with all the posts and links that were owned by the old “admin” user. You should select “Attribute all posts and links to” and select your new user you just created earlier from the drop down list.
Now that you have deleted the old “admin” user account, all the old blog posts that were created under that username will be reassigned to your new user account you created.
