To disable password resets by users on MySQL, you can follow these steps:
- Connect to the MySQL server as a user with administrative privileges. You can use the command line tool or a graphical client like phpMyAdmin.
- Run the following command to select the MySQL user account that you want to disable password resets for: SELECT User, Host FROM mysql.user;
- Identify the user account for which you want to disable password resets, and make a note of its name and host.
- Run the following command to revoke the "ALTER" privilege for the user account, which prevents them from resetting the password: REVOKE ALTER ON *.* FROM 'username'@'host'; Replace 'username' with the actual username and 'host' with the actual host of the user account.
- Finally, run the following command to flush the privileges and apply the changes: FLUSH PRIVILEGES;
After completing these steps, the user account specified will no longer be able to reset their own password. It's crucial to ensure that you have administrative access in case you need to make any changes or reset passwords for users in the future.

How do I modify the settings in MySQL to prevent password resets by users?
To modify the settings in MySQL to prevent password resets by users, you can disable the password reset functionality by following these steps:
- Access the MySQL configuration file: Depending on your operating system, the configuration file can be located at different paths. Commonly, the path for the configuration file is: Linux/Unix: /etc/mysql/my.cnf or /etc/my.cnf Windows: C:\Program Files\MySQL\MySQL Server X.Y\my.ini
- Open the MySQL configuration file in a text editor.
- Search for the [mysqld] section in the configuration file. If the section doesn't exist, you can add it.
- Add the following line to the [mysqld] section to disable password resets: skip-grant-tables This configuration option allows anyone to connect to the MySQL server without a password and with all privileges. It effectively disables the authentication mechanism. Be cautious when using this option as it removes all password restrictions.
- Save and close the configuration file.
- Restart the MySQL service to apply the changes. The method to restart the service depends on your operating system. For example: Linux/Unix: Use the command sudo service mysql restart or sudo systemctl restart mysql.service. Windows: Restart the MySQL service through the "Services" management console.
After disabling the password reset functionality, users will not be able to reset their passwords. However, it is essential to ensure the security of your MySQL server by enforcing other security measures and regular password changes for administrative accounts.
What is the recommended approach to disabling password resets by users on MySQL?
The recommended approach to disabling password resets by users on MySQL is to modify the user account privileges and revoke the ALTER privilege, which is required to change the password.
Here are the steps to follow:
- Connect to your MySQL server using a privileged account, such as the root account.
- Execute the following SQL command to revoke the ALTER privilege for the desired user:
1
|
REVOKE ALTER ON *.* FROM 'username'@'localhost';
|
Replace 'username' with the actual username of the user whose password reset you want to disable.
- Execute the FLUSH PRIVILEGES; command to apply the changes:
1
|
FLUSH PRIVILEGES;
|
By revoking the ALTER privilege, the user will no longer have permission to modify their own password or anyone else's password.

- Find the [mysqld] section in the configuration file.
- Add the following line to the [mysqld] section: skip-grant-tables.
- Save and close the configuration file.
- Restart the MySQL service to apply the changes. The command may vary depending on your operating system. For example, on Linux, you can use sudo service mysql restart or sudo systemctl restart mysql.

How do I disable password reset functionality for users in MySQL?
To disable the password reset functionality for users in MySQL, you can follow these steps:
- Connect to your MySQL server as a user with administrative privileges (e.g., the "root" user).
- Run the following command to access the MySQL command-line interface: mysql -u root -p
- Enter your MySQL root password when prompted.
- Once you are in the MySQL command-line interface, switch to the MySQL system database by running the following command: use mysql;
- To disable the password reset functionality, you need to update the "plugin" column of the user table with an invalid value. You can use the following command to achieve that: UPDATE user SET plugin = 'invalid' WHERE User = 'username'; Replace "username" with the actual username for which you want to disable the password reset functionality.
- After updating the user table, you need to run the following command to flush the privileges: FLUSH PRIVILEGES;
- Finally, exit the MySQL command-line interface by running: exit;
This process will disable the password reset functionality for the specified user. They will no longer be able to reset their password using the standard MySQL password reset mechanisms.
