How can we change MySQL user password by using UPDATE statement?

To change MySQL user password with the help of UPDATE statement, we need to update the ‘user’ table of the ‘mysql’ database. Its syntax would be as follows −

Syntax

USE mysql;
UPDATE user
SET authentication_string = PASSWORD(‘new_password’)
WHERE user = user_name AND host = host_name;

The first two statements will be common because to change the password for MySQL user we need to use MySQL database and update the user table.

• New_password would be new password we want to set for MySQL user
• User_name is the name of the current user.
• Host_name is the name of the host of the current user.

Example

Suppose if we want to change the password user@localhost to ‘tutorials’ then it can be done as follows −

USE mysql;
UPDATE user
SET authentication_string = PASSWORD('tutorials')
WHERE user = 'user' AND
   host = 'localhost';
FLUSH PRIVILEGES;
