What is the database prefix setting for All in one Security?

Many people probably do a quick install of WordPress. The database name is automatically generated, but in many cases it is set to "wp_" by default, which is dangerous because it is easily deciphered, so this function converts it to a different prefix.

Since the database name will change, please back up the database before proceeding.
