MariaDB default password & login
MySQL fork. Default root user has NO password on most distros — secure with mysql_secure_installation immediately.
Use these credentials for the very first login to MariaDB only. The full vendor documentation linked below explains how to rotate them and harden the install.
Notes & recovery
On Debian root uses unix_socket auth; password is set via mysql_secure_installation. On RHEL the password is blank.
Official documentation →Change the default immediately
Anyone with internet access can try the published default on MariaDB. Set a strong, unique password the moment you finish first-time setup, ideally before exposing the service to your LAN.
