When you installed WordPress, it automatically created a user with administrative powers for you. This role is called administrator, and every WordPress site must have at least one admin account (you will not be allowed to delete them all). As you have already seen in the earlier chapters, administrators can do everything.
In general, you don't want to have a lot of administrators on a single blog or website. It is best to keep just one administrator account on a blog with 10 to 20 authors and editors, or perhaps up to three administrators for a blog with dozens of users.
Some examples of the actions that only a user with the administrator role can perform are as follows:
- Switch blog theme
- Add, edit, activate, or deactivate plugins
- Add, edit, or delete users
- Manage general blog options and settings
When creating more administrator accounts (or managing the main one), make sure to use only complex passwords that are hard to break using any sort of brute-force methods. As we mentioned previously, a lot of hacking attempts revolve around password guessing, so the more complex your password is, the tougher it will be to break.
