Bluedragon default password

I started digging and managed to login to at bluedragon/administrator/index.cfm with a default password. This seems very insecure since I could add or delete datasources at will. Is it OK to change the password on that, or will it break something?

This is your own installation and you are responsible for your server.
hence, you should change the password.

Thanks! Didn’t want to do it without checking.
