Now what if we had multiple accounts or we had a non root account and a root account. We don't want to log out every time we want to switch users right? For this we would use the "su" command
$ su jan
Did you get that? at the command prompt you would type in "su name_of_user_you_are_switching_to". The system then prompts you for a password by showing us "password:" Here you simpley type in that users password and hit enter. Now when typing in do not be surprised if you don't see squat. You will not see ******* or plain charaters. See this way no on knows how many charaters your password is even if they sre right behind you.
In short nothing is wrong.Now you are loged in as whoever you chose to login as.
