Working with MySQL in Metabase
Connecting to MySQL 8+ servers
Metabase uses the MariaDB connector to connect to MariaDB and MySQL servers. The MariaDB connector does not currently support MySQL 8’s default authentication plugin, so in order to connect, you’ll need to change the plugin used by the Metabase user to mysql_native_password: ALTER USER 'metabase'@'%' IDENTIFIED WITH mysql_native_password BY 'thepassword';
If you’re still experiencing problems connecting, please refer to the troubleshooting guide.
Read docs for other versions of Metabase.
