Here’s a reason why you shouldn’t let anyone use your computer.
In your terminal, type:
security dump-keychain -d ~/Library/Keychains/login.keychain
If your passwords starts printing out right away, that means anyone using your computer can see all your passwords.
You need to do this:
1. Open Up Keychain Access (Using SpotLight, Alfred, or Quicksilver)
2. Click on the lock Button:
If your computer asks you to input your computer password, then now you know how IMPORTANT your computer password is. Never share it.
If you’ve seen enough passwords, type Control+C in your terminal to stop it.
