Addressing MySQL Error 1131: Resolving Anonymous User Password Change Issues

When working with MySQL, security is a paramount concern, and managing user permissions correctly is a critical part of maintaining a secure database environment. If you’ve encountered Error 1131 – SQLSTATE: 42000 (ER_PASSWORD_ANONYMOUS_USER) You are using MySQL as an anonymous user and anonymous users are not allowed to change passwords, it means that you’re attempting to perform a password change operation without proper user authentication. Let’s explore how to diagnose and fix this issue to regain full control over your MySQL user accounts.

Understanding the Error

MySQL Error 1131 occurs when a client connects to the MySQL server without specifying a username, resulting in an anonymous session. During such a session, the server restricts certain actions, including changing passwords, because it cannot associate the session with a specific user account with the requisite privileges.

Diagnosing the Issue

To diagnose the problem, ensure that you are connecting to the MySQL server with a valid username. You can check the current user you are connected as with the following command:


Fixing the Error

Here are the steps and sample code to resolve the error:

Step 1: Connect with a Valid User Account

Make sure to connect to the MySQL server using a valid username and password:

mysql -u valid_username -p

Enter the password when prompted, and then attempt the password change operation again.

Step 2: Identify and Remove Anonymous Accounts

Anonymous accounts can pose a security risk. Identify any anonymous accounts on your MySQL server:

SELECT User, Host FROM mysql.user WHERE User = '';

If you find any, consider removing them:

DROP USER ''@'localhost';

Replace localhost with the appropriate host if the anonymous account is associated with a different host.

Step 3: Change Password Using an Authenticated Session

Once connected with a valid user that has the necessary privileges, you can change the password using the ALTER USER command:

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

Replace valid_username, localhost, and new_password with the appropriate username, host, and new password.

Step 4: Assign Proper Privileges to Users

Ensure that all user accounts have the correct privileges to perform their required tasks:

GRANT ALL PRIVILEGES ON database_name.* TO 'valid_username'@'localhost';

Replace database_name with the name of the database you want the user to have privileges on.

Step 5: Flush Privileges

After making changes to user accounts or privileges, make sure to reload the privileges:


By following these steps, you can resolve MySQL Error 1131 and ensure that all password changes are performed by authenticated users with the correct privileges. It’s also good practice to regularly audit your user accounts and privileges to maintain a secure database environment. If you’re unsure about these procedures or need further assistance, it’s advisable to consult with a database administrator or refer to the MySQL documentation for more detailed guidance.
