Users password

Passwords ensure that no one except the owner of the accout can use the account. Because of this you are never to let anybody know your password and it must be chosen so that it's not easy to guess. From this page you find some instructions for picking a good password and changing your password.

IMPORTANT: Only you should know your password. Never tell your password to anyone, not even the administration - the real administrators do not need to know your password and will never ask for it. Also never send your password over e-mail or over an unencrypted communication channel.

Lintula password and other passwords at TUT

Lintula username and password are used for all Lintula systems including:

• Lintula Linux workstations and Laptops and Lintula SunRay terminals

In addition to Lintula password, students and staff members at TUT also have TUT Intranet username and password. TUT Intranet password and Lintula password are separate and must be changed separately. TUT Intranet password is used with TUT centralized systems. More information about TUT Intranet password can be found at tutka or at TUT public www-pages.

TST Windows workstation users also have separate password for Windows workstations. More information about TSTWin password can be found at tstwin www-pages. TSTWin password should always be same as users Lintula password.

Tips for picking a good password

Good password should have the following:

• Password is not a word from any language (or even constructed from word by e.g. changing i to 1 or adding a number at the end of word).
  
• Password is at least 10 characters long,preferably longer. Password can also be a lot longer, ie passphrase.
• Includes lower and upper case characters and numbers (but not special characters).
• Password should be changed often enough (TUT policy requires users to change their passwords every 9 month).
• Password should be remembered without writing it down.
• Passwords should not be reused. When you change your password, you should invent a new password.

Using TUT passwords (including the Lintula password) on systems outside TUT is prohibited. You may use same password for Lintula and TUT Intranet as long as your password is good enough. More information about TUT password policy, TUT Intranet password and inportance about the password can be found on Tutka > IT > User accounts > Password > About password and its importance

We are regularly running a test program for too easy passwords. If your password is so easy that it gets guessed, your account is closed immediately. Account is opened when you visit room TC224 (during meeting hours) and get new password (you need some identification e.g. student card).
