Don't log in as root. Don't bypass security. Even if you are the only one on your box and that box is NEVER connected to a network including the internet.
Root is extremely powerful and therefore a danger to you and your set up. One mistake in a command line entry and ALL of your files will be gone or corrupted or copied over with some other file with little to no chance of getting them back.
Linux gives you plenty of tools to manage your daily activities as a "normal" user. The sudo tool is the best, setting up permissions and groups is also very good. Occasionally switching to root with the "su -" command is O.K. to help you set up some permissions and groups, too, followed by "su <normal user name>".
Of course, it's your choice, but Linux is not a toy it's a serious operating system that is extremely powerful, very flexible, highly configurable and doesn't care if you really meant to enter that last command or not
