Mysql is an open source database management system that is widely used in different web applications and larger enterprise-level systems. It can store large amounts of data securely, but you may run into problems if you forget your password or need to change it. In this article, we will introduce several methods to view Mysql password.

The first method is to use a Mysql client program, such as Mysql Workbench or Mysql command line client. After entering the Mysql command line, run the following command in the console:

SELECT User, Host, Password FROM mysql.user;

This command will return a user list and corresponding password, as well as the corresponding host name. If you know which username you are using, you can display only specific users. For example, to display the password of the user named "user1" and its host name, use the following command:

SELECT Password FROM mysql.user WHERE User='user1';

The second method is to view the configuration file of Mysql. By looking at the configuration file we can get where the passwords are logged. Use the following command to find the address of the Mysql configuration file:

sudo grep -r 'datadir' /etc/mysql/

This command will return a result similar to the following:

/etc/mysql/mysql.conf.d/mysqld.cnf:datadir=/var/lib/mysql

In this result, we need to look at the mysqld.cnf file because This file contains database configuration information. Use the following command to open the mysqld.cnf file for viewing:

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Find the following string in the file:

plugin-load=auth_socket.so

Change it to the following string:

#plugin-load=auth_socket.so

Then save and close the file. Now we can access the Mysql console by using the following command on the command line:

mysql -u root -p

Then in the console we can view the user list and password using the following command:

SELECT User, Host, Password FROM mysql.user;

Third One way is to use an online decryption tool, but this is not recommended. Online decryption tools are very insecure. Using this method requires sending sensitive information to an untrusted server, which may lead to password leakage.

To sum up, if you forget your Mysql password, you can use the first or second method. If you're not sure which method is better for your situation, start with the first method. However, forgetting passwords is a common security problem. To protect your database, please remember to record passwords during daily use and keep them properly.
