When you enter the University of Helsinki as a student, a user account to the university’s IT environment will be created for you. The user account, besides giving you the right to use the system, contains your essential personal information, and information on how long your account is valid. The user account data also includes information on when you will have to change your password to the system so that it does not become invalid. All user accounts come with a personal username. The username and password together form a key with which you can access the computer system to which you have a user account.
