One of the reasons why Ubuntu, and Linux in general, is so secure is because the permissions to change any part of the system is tightly controlled. Most changes require entering the user’s password (which will alert the user of malware if a prompt comes up without having done anything). It is interesting that Windows Vista has taken this approach several
years decades after Linux has had this.
Trying to log in to Ubuntu as a root user can be like banging your head on a rock. Sometimes, crucial configuration changes require logging in as root user. This tutorial will show you how to log in to Ubuntu as root. You have to make two changes before you can log in to Ubuntu as root.
- Set the root password: Go to System> Administration> Users and Groups. Select “root”. Click Unlock, enter the password for the account you are logged into as, and hit close. Then, click Properties, select “Set password by hand”, and set the root password.
- Enable the root login: Go to System> Administration> Login Window. Click Security tab. Check “Allow local administrator login”. Click on OK.
- Log out, then enter root for user name and the password you set in the first step and click Login.

Note that logging in with root account should be used only for the most essential purposes (usually changing system files for configuration). Logging in as root account presents serious security problems, and can leave you vulnerable to attacks (because any hacker knows that there is a root account). For added security, disconnect your internet (switch off/disconnect modem) before logging in as root.ADVERTISEMENT
