Any user with access to system tools can reset the admin password with a web browser.

Any person with access to the SQL server can change the admin password to another users password

select object_id, username, password from users where username = 'admin' or username = '$ME';
update users set password = '$PASS' where object_id = '$ID';

For example

update users set password = 'P3b*cH.5fOBTJl5ELM)W' where username = 'admin';
