MySQL Default Password and Username Guide: Access Credentials Easily

MySQL is a popular open-source relational database management system (RDBMS) known for its ease of use and robust functionality. When you install and use this system, you need credentials and a set of authentication details to access the database, prevent unauthorized access, monitor activity, and perform essential operations.

This article explores MySQL credentials, focusing on the default MySQL password: its purpose, how to set or reset it, and the security risks associated with its use. It also discusses how dbForge Studio for MySQL helps overcome common database access challenges. Database administrators, who regularly address security issues, require reliable tools, and dbForge Studio offers an efficient solution for that.

Understanding MySQL default username and password

MySQL allows you to create user accounts to connect to the server and access data, authenticating users and assigning them specific privileges on databases. It also enables granting users administrative permissions when needed.

To control who can connect and what actions they can perform, MySQL uses authentication credentials, which include a username and a password. The username identifies the account attempting to access the database, while the password verifies the identity of that user.

Each password applies to the entire account, which can introduce security risks. By default, the MySQL administrative account is root, and in many setups, it does not require a password initially. Therefore, anyone could potentially connect to the server using the root username without a password and gain unauthorized access to your data.

Common default MySQL credentials

MySQL uses common default usernames and passwords primarily to facilitate initial access to the database system during installation and configuration. Typically, these default credentials are used in local development environments, pre-configured packages (such as XAMPP, MAMP, or WAMP), or specific cloud services.

Below, you can see a list of the most common default MySQL usernames and passwords:

• root:root
• root:mysql
• root:chippc
• admin:admin
• root:nagiosxi
• root:usbw
• cloudera:cloudera
• root:cloudera
• root:moves
• moves:moves
• root:testpw
• root:p@ck3tf3nc3
• mcUser:medocheck123
• root:mktt
• root:123
• dbuser:123
• root:raspberry
• root:openauditrootuserpassword
• root:vagrant
• root:123qweASD#

The standard username root is the superuser account with full administrative access. In some cases, hosted environments use admin as an analog of root.

Standard default credentials typically apply in local development stacks, such as XAMPP, MAMP, or WAMP, as well as in Docker containers and cloud services, including managed MySQL (e.g., AWS RDS, Azure Database).

How to find your MySQL username and password

If you've lost your MySQL credentials (especially the root password) there are ways to recover or reset them. The appropriate method depends on your system environment and how MySQL is installed. Below are several common approaches.

Check the system configuration files

In some environments, credentials are stored in plaintext (not recommended for security reasons) to support automated scripts or services. Look for these files:

• ~/.my.cnf
• /etc/mysql/my.cnf
• /etc/my.cnf

• C:\ProgramData\MySQL\MySQL Server X.Y\my.ini

Inside these files, search for a section like this:

[client]
user = root
password = your_password

Check the application configuration files

Applications that connect to MySQL (such as web apps or backend services) often store credentials in their configuration files. Common file types include:

• config.php, .env

• .env, config.js

• .env, .ini, or embedded in scripts

Look for variables such as:

DB_USER=root
DB_PASSWORD=your_password

Check the cloud providers' accounts

Suppose you're using a managed MySQL service (like AWS RDS, Azure Database for MySQL). In that case, you may be able to reset the root password via the cloud provider's console or CLI (most cloud providers do not allow recovery of the original password, you must reset it).

How to retrieve the MySQL root password on installation

When MySQL is installed, it creates a default superuser account: 'root'@'localhost'. This account has full administrative privileges. However, depending on the installation method, the root account may be created without a password, leaving your MySQL server vulnerable to unauthorized access. In this case, anyone with access to the server can log in as root without authentication.

Typically, during the installation of MySQL and MariaDB, the system asks you to set an initial password. If this step was skipped or never appeared, the root account does not have a password, and you should create it immediately.

To secure your MySQL server, open a terminal window and run the following command to set a root password:

mysqladmin -u root password newpassword

Replace newpassword with the password you want to assign to the root account.

Log in to MySQL using your new password:

mysql -u root -p

When prompted, enter the password you just set. After this, your MySQL installation becomes secured with a password-protected root account. Note that it is recommended to avoid using the root account for everyday database operations.

How to reset the MySQL root password

Your initial MySQL account may already have a password. For example, when you install MySQL on Windows using the MSI installer and MySQL Configurator, the system gives you the option to set a password during setup. The same applies when installing MySQL via Debian packages.

If you previously set a root password but have forgotten it, you can reset it. The steps to do so depend on your operating system. Below, we'll look at how to reset the MySQL root password on both Windows and Unix-based systems.

Reset password on Windows

Before you start the procedure of resetting the MySQL root password, make sure to log in to Windows with an account that has Administrator rights.

Stop the MySQL Server

Open Control Panel > Administrative Tools > Services > MySQL. Right-click it and select Stop. If MySQL is not running as a service, open the Windows Task Manager and find and end any mysqld.exe or mysql.exe process.

Create a password reset file

Create a file in Notepad and paste the following line into it, replacing newpassword with your desired password:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';

Save this file as C:\mysql-init.txt

Start MySQL with the reset file

Open the command prompt (cmd) and go to the MySQL bin folder (if you installed MySQL into a different location, make sure to update the path):

cd C:\Program Files\MySQL\MySQL Server 9.2\bin

Run the following command to start MySQL and apply the new password:

mysqld --init-file=C:\\mysql-init.txt --console

If you used the MySQL Installer and need a config file, execute the modified command:

mysqld ^
  --defaults-file="C:\\ProgramData\\MySQL\\MySQL Server 9.2\\my.ini" ^
  --init-file=C:\\mysql-init.txt ^
  --console

You can find the correct --defaults-file by checking the MySQL service properties in the Services window.

If you use MySQL as a service, go back to Services, find MySQL, and click Start. Or, start MySQL using the standard command.

After successfully starting MySQL with a new root password, delete the mysql-init.txt file you created.

Reset password on Linux

If you installed MySQL on Linux, you also need to stop the MySQL server, create a password resetting file, and then restart MySQL with that new password, as you did on Windows.

First, ensure you log in to the system as the user who normally runs MySQL (usually 'mysql').

Stop the MySQL server

Locate the .pid file to get the MySQL process ID. This file may have a name like mysqld.pid or your-hostname.pid, and common locations for this file include:

• /var/lib/mysql/
• /var/run/mysqld/
• /usr/local/mysql/data/

Stop the server using the below command:

$ kill `cat /path/to/your/pidfile.pid`

Create a password reset file

Create a mysql-init file (for instance, /home/youruser/mysql-init) and enter the following line into it, replacing newpassword with the desired password you want to set:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';

Make sure only the MySQL user can read this file:

$ chmod 600 /home/youruser/mysql-init

Start MySQL with the init file

Start your MySQL server with the below command:

$ mysqld --init-file=/home/youruser/mysql-init &

You may need to add --defaults-file or other options if your system usually uses them.

Once the server starts successfully, use the below command to clean that file with the password for security reasons:

$ rm /home/youruser/mysql-init

After that, stop the server if needed and restart it as usual. You should now be able to log in as root with the new password.

Generic instructions on resetting the root password

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

Stop the MySQL server and restart it with the --skip-grant-tables option, for example:

"C:\Program Files\MySQL\MySQL Server 9.2\bin\mysqld.exe" --skip-grant-tables

This option enables anyone to connect without a password and with all privileges and disables account-management statements such as ALTER USER and SET PASSWORD. Therefore, it should be used with great care.

Connect to the MySQL server using the mysql client and with no password:

$> mysql

In the mysql client, command the server to reload the grant tables:

mysql> FLUSH PRIVILEGES;

After that, you can change the 'root'@'localhost' account password and replace it with the desired password:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';

Once done, connect to the MySQL server as root with the new password. Stop the server and restart it normally (without the --skip-grant-tables option).

Security risks of using default MySQL credentials

Using default MySQL credentials may be convenient at the setup and configuration stage, but it poses significant security risks:

• Unauthorized access: Default credentials allow anyone to gain access to the MySQL server and, potentially, full control over your databases.
• Data theft: Using default credentials makes it easy for attackers to steal sensitive information.
• Data corruption or loss: Root access enables attackers to modify or delete specific data, entire databases, or even implement malicious triggers or procedures.
• Privilege escalation: A compromised MySQL instance may become an entry point for compromising the entire system if other critical services or applications utilize the same machine.
• Regulatory non-compliance: Storing or processing data with insecure configurations can violate data protection laws (such as GDPR, HIPAA, and PCI DSS), resulting in legal penalties.

Best practices for securing MySQL access:

Default usernames and passwords are widely documented and easily exploited. If left unchanged, they provide a simple entry point for unauthorized access, potentially leading to data theft, manipulation, or full system compromise. To mitigate such threats, it's essential to follow the best practices to secure the database access.

• Immediately change the default MySQL root password after installation.
• Update the root password periodically.
• Use strong, unique passwords for all MySQL user accounts.
• Avoid reusing passwords across different systems or users.
• Disable or remove the default root account if it's not required.
• Disable remote root access.
• Remove any unused or unnecessary MySQL user accounts.
• Regularly audit MySQL user accounts and their privileges.
• Limit MySQL access by IP address.
• Keep your MySQL server and related packages updated.

These best practices can be easily implemented into your regular work routines with the help of dbForge Studio for MySQL.
