How to Change a MySQL User Password

As a database administrator or a developer working with MySQL, you may need to change the password of a user for various reasons, such as security updates or user requests. In this guide, we’ll walk you through the process of changing a MySQL user’s password, explaining each step in detail to ensure both experts and novices can follow along easily. We’ll use appropriate markdown syntax for headings and formatting to make the text more engaging.

Step 1: Log in to the MySQL Shell as Root

To change a user’s password in MySQL, you must first log in to the MySQL shell with root privileges. Root access allows you to perform administrative tasks, such as modifying user permissions and passwords. To log in to the MySQL shell as root, open a terminal or command prompt and enter the following command:

mysql -u root -p

After running this command, you’ll be prompted to enter the root password. Type in the password and press Enter to access the MySQL shell.

Step 2: Set the MySQL User Password

Once you’ve successfully logged in to the MySQL shell with root privileges, you can proceed to change the desired user’s password. First, you’ll need to select the database containing the user information, which is typically stored in the mysql database. To select the mysql database, run the following command:

USE mysql;

Next, you’ll need to update the password for the specific user. For this, you can use the ALTER USER statement followed by the IDENTIFIED BY clause to specify the new password. Replace your_user with the actual MySQL username and new_password with the desired new password. Here’s the command:

ALTER USER 'your_user'@'localhost' IDENTIFIED BY 'new_password';

After executing this command, the password for the specified user will be updated. To apply the changes immediately, you should flush the privileges by running the following command:

Step 3: Verify the New Password

Now that you’ve changed the user’s password, it’s essential to verify that the new password works correctly. To do this, exit the MySQL shell by typing exit and pressing Enter.

Then, try logging in to the MySQL shell using the updated user credentials. Replace your_user with the actual MySQL username and new_password with the updated password:

mysql -u your_user -p

When prompted, enter the new password. If the login is successful, this confirms that the password change was successful, and you’ve completed the process.


In this guide, we’ve shown you how to change a MySQL user’s password by logging in to the MySQL shell as root, updating the user’s password, and verifying the new password. We’ve provided clear explanations for each command to ensure that both expert and novice readers can understand the process. Remember to use strong, unique passwords and update them regularly to maintain the security of your MySQL databases.
