Table Prefix Basics
WordPress uses a database to store data. This data includes posts, users, and settings. Each piece of data goes into a table. Tables have names. These names begin with a table prefix. By default, WordPress uses “wp_” as the prefix. So, a table might be named “wp_posts”.
Changing the table prefix can add security. Hackers often target default settings. A unique prefix makes it harder for them. Imagine using “abc_” instead of “wp_”. Now, your table is “abc_posts”.
Always remember to use a prefix that is easy to remember. But also, make it hard for others to guess. Choose a mix of letters and numbers. This simple step can help keep your site safe.
