Refer to the following link to learn how to access your Maria DB (you can also use MySQL Workbench if you have that installed)

You can find more detailed information about resetting your Maria DB password in the External Link.

If this solution does not resolve your issue, unfortunately we can only provide limited support on restoring your Maria DB root password.
You can also try different solutions you search online.

Another solution would be to back up your Maria Database, delete BioStar, reinstall BioStar, and restore the database. 

Then you can configure your root password again in the installation phase.

You can try backing up your database with your default account if you use a BioStar version lower than 2.4.1 (or if you upgraded from an older version). 

The default accounts are listed in the article below:
