On Unix, use the following procedure to reset the password for the MySQL 'root'@'localhost' account. To change the password for a root account with a different host name part, modify the instructions to use that host name. The instructions assume that you will start the MySQL server from the Unix login account that you normally use for running it.

If you have never assigned a root password for MySQL, the server does not require a password at all for connecting as root. However, this is insecure. For instructions on assigning passwords, see Section 2.10.4, “Securing the Initial MySQL Accounts”.

If you know the root password and want to change it, see Section 13.7.1.6, “SET PASSWORD Syntax”.

If you assigned a root password previously but have forgotten it, you can assign a new password. The following sections provide instructions for Windows and Unix and Unix-like systems, as well as generic instructions that apply to any system.

B.4.3.2.1 Resetting the Root Password: Windows Systems

On Windows, use the following procedure to reset the password for the MySQL 'root'@'localhost' account. To change the password for a root account with a different host name part, modify the instructions to use that host name.

Log on to your system as Administrator.
Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it to stop.
Create a text file containing the following statement on a single line. Replace the password with the password that you want to use.
Save the file. This example assumes that you name the file C:mysql-init.txt.
Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.
Start the MySQL server with the init_file system variable set to name the file (notice that the backslash in the option value is doubled):
If you installed MySQL to a different location, adjust the cd command accordingly.
The server executes the contents of the file named by the init_file system variable at startup, changing the 'root'@'localhost' account password.
To have server output to appear in the console window rather than in a log file, add the --console option to the mysqld command.
If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option. For example:
The appropriate --defaults-file setting can be found using the Services Manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
After the server has started successfully, delete C:mysql-init.txt.

You should now be able to connect to the MySQL server as root using the new password. Stop the MySQL server and restart it normally. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.

B.4.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems

On Unix, use the following procedure to reset the password for the MySQL 'root'@'localhost' account. To change the password for a root account with a different host name part, modify the instructions to use that host name.

The instructions assume that you will start the MySQL server from the Unix login account that you normally use for running it. For example, if you run the server using the mysql login account, you should log in as mysql before using the instructions. Alternatively, you can log in as root, but in this case you must start mysqld with the --user=mysql option. If you start the server as root without using --user=mysql, the server may create root-owned files in the data directory, such as log files, and these may cause permission-related problems for future server startups. If that happens, you will need to either change the ownership of the files to mysql or remove them.

Log on to your system as the Unix user that the MySQL server runs as (for example, mysql).
Stop the MySQL server if it is running. Locate the .pid file that contains the server's process ID. The exact location and name of this file depend on your distribution, host name, and configuration. Common locations are /var/lib/mysql/, /var/run/mysqld/, and /usr/local/mysql/data/. Generally, the file name has an extension of .pid and begins with either mysqld or your system's host name.
Stop the MySQL server by sending a normal kill (not kill -9) to the mysqld process. Use the actual path name of the .pid file in the following command:
Use backticks (not forward quotation marks) with the cat command. These cause the output of cat to be substituted into the kill command.
Create a text file containing the following statement on a single line. Replace the password with the password that you want to use.
Save the file. This example assumes that you name the file /home/me/mysql-init. The file contains the password, so do not save it where it can be read by other users. If you are not logged in as mysql (the user the server runs as), make sure that the file has permissions that permit mysql to read it.
Start the MySQL server with the init_file system variable set to name the file:
The server executes the contents of the file named by the init_file system variable at startup, changing the 'root'@'localhost' account password.
Other options may be necessary as well, depending on how you normally start your server. For example, --defaults-file may be needed before the init_file argument.
After the server has started successfully, delete /home/me/mysql-init.

You should now be able to connect to the MySQL server as root using the new password. Stop the server and restart it normally.

B.4.3.2.3 Resetting the Root Password: Generic Instructions

The preceding sections provide password-resetting instructions specifically for Windows and Unix and Unix-like systems. Alternatively, on any platform, you can reset the password using the mysql client (but this approach is less secure):

Stop the MySQL server if necessary, then restart it with the --skip-grant-tables option. This enables anyone to connect without a password and with all privileges, and disables account-management statements such as SET PASSWORD. Because this is insecure, you might want to use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting.
Connect to the MySQL server using the mysql client; no password is necessary because the server was started with --skip-grant-tables:
In the mysql client, tell the server to reload the grant tables so that account-management statements work:
Then change the 'root'@'localhost' account password. Replace the password with the password that you want to use. To change the password for a root account with a different host name part, modify the instructions to use that host name.

You should now be able to connect to the MySQL server as root using the new password. Stop the server and restart it normally (without the --skip-grant-tables and --skip-networking options).

This tutorial explains how you can set, change and reset (if you've forgotten the password) MySQL or MariaDB root passwords. Time and again I see problems like mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: YES)'. So I thought it's time to remind you how to solve MySQL related password problems. If you are just looking for a quick fix how to reset a MySQL root password you can find that at the bottom of this tutorial. This tutorial is compatible with all major Linux Distributions incl. CentOS, Debian, Fedora, and Ubuntu.

mysqladmin Command To Change Root Password

Method 1 - Set up a root password for the first time

If you have never set a root password for MySQL, the server does not require a password at all for connecting as root. To set up a root password for the first time, use the mysqladmin command at the shell prompt as follows:

If you want to change (or update) a root password to the new password 'newpass', then you need to use the following command:

If you get...

then follow the instructions below on how to recover your MySQL password.

The word 'password' in the above example is part of the command, do not replace that with your password. The word 'newpass' is the new password.

An alternative to using the mysqladmin command when setting the MySQL or MariaDB root password the first time is to use the mysql_secure_installation command. This command will not only ask for the old- and new MySQL root password but will also do some other security settings like disabling the test database.

Here is how to use that command:

Answer the questions as shown below:

The above answers are recommendations, you are free to choose other settings e.g. when you prefer to keep the test databases or need remote access for the root user. Note: you do not need remote access to use PHPMyAdmin remotely.

Change MySQL password for other users

To change a normal user password you need to type:

The variables in this example are:

user-name: The username of the user that you want to change the password for.
newpass: The new password

The word 'password' is not a variable, so do not replace it. The command will ask for the old password.

Method 2 - Update or change password

MySQL stores usernames and passwords in the user table inside the MySQL database. You can directly update a password using the following method to update or change passwords:

1) Login to the MySQL server, type the following command at the shell prompt:

2) Use the mysql database (type commands at the mysql> prompt):

3) Change password for a user:

MySQL 5.7.5 and earlier

MySQL 5.7.6 and newer

4) Reload privileges:

This method you need to use while using PHP or Perl scripting.

Recover MySQL root password

You can recover a MySQL database server password with the following five easy steps:

Step # 1: Stop the MySQL server process.

Step # 2: Start the MySQL (mysqld) server/daemon process with the --skip-grant-tables option so that it will not prompt for a password.

Step # 3: Connect to the MySQL server as the root user.

Step # 4: Set a new root password.

Step # 5: Exit and restart the MySQL server.

Here are the commands you need to type for each step (log in as the root user):

Step # 1: Stop the MySQL service:

Output:

Step # 2: Start the MySQL server w/o password:
