Changing MySQL User Password

You have the version of the running MySQL server. Use one of the following commands to change the MySQL user password as per of database server version running on your system.

In the below SQL statements, make sure to change dbuser with your database user and localhost with the user’s host.

• First of all, check for the existing user and corresponding host.
  mysql> SELECT User,Host FROM mysql.user WHERE User='dbuser';;

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

  Output
  +--------+-----------+
  | User   | Host      |
  +--------+-----------+
  | dbuser | localhost |
  +--------+-----------+
  1 row in set (0.00 sec)
  

• Use the ALTER USER to change MySQL user password for the MySQL database server version 5.7.6 or newer versions:
  mysql> ALTER USER 'dbuser'@'localhost' IDENTIFIED BY 'new-password';

  1	mysql> ALTER USER 'dbuser'@'localhost' IDENTIFIED BY 'new-password';

  

• For the MySQL database server version 5.7.5 or older version, Use the “SET PASSWORD” statement to change a MySQL user password using SQL queries.
  mysql> SET PASSWORD FOR 'dbuser'@'localhost' = PASSWORD('new-password');

  1	mysql> SET PASSWORD FOR 'dbuser'@'localhost' = PASSWORD('new-password');

  

Understanding MySQL User Password Basics

The first step in changing your MySQL user password is to understand the basics of MySQL user passwords. MySQL user passwords are used to authenticate the user that is attempting to access the database. They are typically stored in a separate table in the database and encrypted using a hashing algorithm.

When you create a new MySQL user, you must provide a password that meets certain requirements, such as having at least 8 characters and including both letters and numbers. You should also be sure to create a unique password for each user, as this will help to prevent unauthorized access to the database.

Once you have created a new MySQL user, you can easily change the user’s password by following the steps outlined in this guide.

Tips for Creating a Strong MySQL User Password

Now that you know how to quickly and easily change your MySQL user password, it is important to ensure that you are creating a strong password. A strong password should include at least 8 characters and include both letters and numbers.

It is also important to avoid using common words or phrases as passwords. If possible, try to use a randomly generated password from a password manager. This will ensure that your password is secure and difficult to guess.

Finally, be sure to create a unique password for each user. This will help to prevent unauthorized access to the database.
