How to Remove User ID 1 and Why

As shown in video above, paste these 3 lines into the SQL section of your cPanels phpMyAdmin – in the correct database.

UPDATE wp_users SET id = 1024 WHERE id = 1;
UPDATE wp_usermeta SET user_id = 1024 WHERE user_id = 1;
UPDATE wp_posts SET post_author = 1024 WHERE post_author = 1;

Also make sure the database table prefix is correct in case you have changed it from wp_ to something else. If you have changed it to something else, then make the correct changes in these 3 lines – replacing wp_ with what you changed yours to.
