Possible silly question.

I have no local security risks. Is it fine to set login to no password?

No, because if the system is networked the same security issues can apply.

it is of course entirely up to you. If you aren´t afraid of hackers etc people who want to hurt your system and or read your files then it´s ok.

Ok, Changed it's name from the default "Administrator" Gave it an excessively long/complex password, and set the permissions on my hard drives/folders/files to only that name.
