Do Not Create a WordPress Site with the Default User 'admin'
Last Update: August 05, 2018
I'm not sure why installation processes for WordPress are still using the user 'admin' as the default but there is a very good reason for changing it or if possible, not creating the site with it in the first place. Using 'admin' sets your site up to get hacked easily. The problem is that most hackers know that most installation of WordPress use user 'admin' and most blog owners never change this. So when they load their scraping programs to guess your credentials, have the work is done. They only have to focus on the password part of it. By choosing a different username, you make it much more difficult for hackers (and their algorithms). If you happen to have installed your blog with that default, it is fairly simple to change. Create a new admin user. Log in to WordPress with that new user. Then you'll be able to delete the 'admin' user at that point. There are other security measures, such as captcha and log in limit plugins that can be implemented but this one is a good start.
