Since the MySQL 8 uses auth_socket plugin in Ubuntu, the above command will let you to login to the MySQL server as root user. To change the authentication plugin, login to MySQL server using command: $ sudo mysql ![]() It provides more secure password encryption, faster authentication, and better performance. In MySQL 8.0, caching_sha2_password is the default authentication plugin rather than mysql_native_password. The caching_sha2_password plugin performs authentication using SHA-256 password hashing. Change authentication plugin to caching_sha2_password #Set root password phpmyadmin ubuntu how toIn this guide, we only discuss two plugins called caching_sha2_password and mysql_native_password that implements the methods called Caching SHA-2 Pluggable Authentication and Native Pluggable Authentication respectively.įirst, we will see how to change authentication method for MySQL root user to caching_sha2_password. MySQL provides many authentication methods and the plugins that implement those methods. Change Authentication Method For MySQL Root User In Ubuntu This is why we need to change the authentication method for MySQL root user in Ubuntu. ![]() They are restricted from connecting remotely. The auth_socket plugin improves the security, but also complicates things when we use external programs like phpMyAdmin to access the database server.Īlso, the users authenticated by the auth_socket plugin can only connect from the local host through the Unix socket file. If the operating system username differs from the MySQL user name, the auth_socket plugin simply refuses the connection. If the plugin finds that the operating system user name and the MySQL user name are same, it permits the connection without further authentication.įor example, if there is a user called ostechnix on the operating system, he/she will be able to login to the account within MySQL if Unix socket authentication is the defined authentication mechanism. It just checks if the user is connecting using a UNIX socket and then compares the username. This plugin doesn’t care and doesn’t need a password. You will get the following error message: ERROR 1698 (28000): Access denied for user auth_socket plugin checks whether the socket user name (the operating system user name) matches the MySQL user name specified by the client program to the server. Even if you try to authenticate as root user using command: $ mysql -u root -p ![]()
