How to change password in MySQL

To change a password for a user in MySQL, you use the ALTER USER statement.

Here are the steps to change a password:

Step 1: Login to MySQL

First, you need to login to MySQL using the mysql command in your terminal or command prompt:

mysql -u root -p

You will be prompted to enter the password for the root user.

Step 2: Change Password

Once you are logged in, you can change the password for a user with the ALTER USER command:

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

Replace 'username' with the name of the user for which you want to change the password, and replace 'new_password' with the new password.

Notes:

Make sure to choose a strong password that includes a mix of letters, numbers, and special characters.
You need the CREATE USER privilege or the UPDATE privilege for the mysql system database to change a password.
If the password is expired or the account is locked, you must have the CREATE USER privilege and the mysql.user table must be updated directly.

Step 3: Flush Privileges

This step is not always necessary, but it's good practice to tell the server to reload the grant tables after changing a password:

FLUSH PRIVILEGES;

Step 4: Exit MySQL

You can exit the MySQL shell by typing:

EXIT;

Remember:

Always ensure that your MySQL server is secure. Never share your passwords and always use strong, unique passwords for your user accounts.
