User Meta refers to the additional information stored about users on a WordPress website, beyond the basic details like username and email. Think of it as customizable fields that let you collect and manage extra data for each user profile.

This data is stored in the wp_usermeta database table and is essential for:

• Extended User Profiles: Adding fields for phone numbers, addresses, or biographies.
• User Roles & Permissions: Storing capabilities and access levels.
• Plugin & Theme Functionality: Many plugins use user meta to save user-specific settings or data.

You can manage user meta through code using functions like get_user_meta(), update_user_meta(), and add_user_meta(). For a non-technical approach, numerous plugins allow you to create custom fields visually. Proper use of user meta helps create personalized user experiences and more powerful membership or community sites.

Remember: While user meta is flexible, avoid storing excessive or sensitive data in it without proper security measures, as it can impact database performance.
