Living at home means that you have to share your computer with other people. In some companies, people also share workstations in case that they have different work shifts. In any case, it is important for you to make sure that your files are safe. Especially those that you use for work and those that contain confidential information.

Here are some tips for you:

• Make sure you are using a password that is not easy to guess.
  If people know you well enough, they could probably figure out what password you will use. People tend to use passwords based on words, names and dates that important to them. Examples are pets‘ names and anniversaries. If you do this, chances are those who know you will be able to log in your computer using your account. Try changing your passwords every so often and make sure that they will be easy for you to remember but difficult to guess. Think of some cipher for it.
• Set permissions on your files and directories.
  You could set that your files and directories will only be accessible to you. Do a chmod on them. Then again, whoever has root access will be able to get through. Maybe it would be easy for you to do this if you are the one with root access.
• Protect your files with passwords.
  Although not everyone agrees with this, some people do this for their own sake. They feel better to have password protected files. A drawback, of course, is that if it has a difficult password to remember, you might as well have deleted your files.
• Log out of your account or profile.
  If you have set your file permissions that you are the only one who can view, edit and execute the files, it will be pointless if you don’t log out. When you are the one who is still logged on, you leave your entire session open for intrusion.

Hopefully these tips have helped you deal with some of your dilemmas with regards to sharing your computer with other users.
