MySQL + SQL · Lesson 106

MySQL Users and Privileges

Managing Users

MySQL lets the DBA create users and give each one only the privileges they need — a core security practice.

Create User & Grant

CREATE USER 'teacher'@'localhost' IDENTIFIED BY 'pass123';
GRANT SELECT, UPDATE ON school.* TO 'teacher'@'localhost';
FLUSH PRIVILEGES;

SHOW GRANTS FOR 'teacher'@'localhost';

Principle of Least Privilege

Give each user only the minimum access they need. A fee clerk should not be able to DROP tables.

Summary

CREATE USER makes accounts; GRANT assigns privileges.
Follow least privilege — minimum access per user.
