Best Practices for Configuring Two-Factor Authentication for MariaDB on CentOS 8
Configuring two-factor authentication (2FA) for MariaDB on CentOS 8 is an essential security measure that helps protect your database from unauthorized access. By adding an extra layer of authentication, you significantly enhance the security of your MariaDB installation. In this tutorial, we will walk you through the best practices for configuring 2FA on MariaDB running on CentOS 8.
To start, ensure that you have MariaDB installed on your CentOS 8 system. If not, you can install it by running the following commands in your terminal:
$ sudo dnf install mariadb-server
$ sudo systemctl start mariadb
$ sudo systemctl enable mariadb
Once MariaDB is up and running, the next step is to enable the 2FA plugin. Begin by logging into your MariaDB server using the root account:
$ sudo mysql -u root -p
After entering the root password, execute the following SQL command to install and enable the plugin:
MariaDB [(none)]> INSTALL PLUGIN two_factor SONAME 'two_factor.so';
Now that the 2FA plugin is installed, we need to create a separate user account that will be required to use 2FA for authentication. Run the following SQL command to create a new user with 2FA enabled:
MariaDB [(none)]> CREATE USER 'myuser'@'localhost' REQUIRE TWO_FACTOR;
Make sure to replace ‘myuser’ with the desired username for your MariaDB account. With the new user created, you can exit the MariaDB shell using the
Next, we need to generate a secret key for the 2FA authentication. Open your terminal and run the following command:
$ otputil show myuser
