What are the benefits of using Auto_INCREMENT for ID fields in database tables?

Using Auto_INCREMENT for ID fields in database tables simplifies the process of generating unique identifiers for each record. It eliminates the need for manually assigning IDs, reduces the chances of duplicate IDs, and ensures that each new record is assigned a unique ID automatically. 

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL
);
