I was looking to restart the SQL Server service, that's when I discovered a way to manipulate the database without logging into the system. See:
3.AccesstheViewmenu>RegisteredServers.NoticethattheObjectExplorerisdisconnected. 
Anyway, this is kinda weird, does anyone know how to solve this? After all if anyone has access to my machine ...
Being a local server that is using the credentials of your local user, the answer is yes , this is normal.
Note, however, that it is normal for a development environment used by a programmer or at most a development or testing team.
In a production environment, a database administrator must correctly configure the minimum permissions required for systems and users that access the database.
