WARNING: Make sure to make a backup of your database before using this setting!
By default, WordPress assigns the prefix "wp" to all tables in the database where your content, users, and objects exist. For potential attackers, this means it is easier to write scripts that can target WordPress databases, as all the important table names for 95% of sites are already known. Changing the "wp" prefix makes it more difficult for tools that are trying to take advantage of vulnerabilities in other places to affect the database of your site. Before using this tool, we strongly recommend running a backup of your database.
To change your WordPress database table' prefix, run the "Change Database Table Prefix" in Security > Tools.
Note: The use of this tool requires quite a bit of system memory which may be more than some hosts can handle. If you back your database up, you can't do any permanent damage, but without a proper backup, you risk breaking your site and having to perform a rather difficult fix.
