About using Two-Step Login (Duo) every time I log into CAS

Important:
  • Beginning November 2, 2017, CAS logins for all IU faculty, staff, students, retirees, affiliates, and those with Academic (ACNP) status will require Two-Step Login (Duo). On November 30, 2017, this will also include group or departmental accounts.
  • Enroll multiple devices and telephone numbers to ensure alternative methods of two-step login, in case you are separated from your main device. For more, see If your Two-Step Login (Duo) device is not with you, or is lost or stolen.
  • This option does not protect your passphrase from being hacked, phished, or otherwise compromised. Think of it as a safety net that protects CAS-authenticated services if your passphrase is compromised.
  • Choose a strong passphrase and take steps to protect it. Don't store the passphrase visibly, do change it periodically, and never share it with anyone.
  • If there is reason to believe your passphrase has been compromised, UITS will scramble it as a precaution.

If you aren't required to complete a Two-Step Login each time you log into CAS, you can enable/disable this feature:

  1. Log into Two-Step Login (Duo). If prompted, log into CAS with your IU credentials and complete a two-step login with Duo. You will receive email notification if your login is completed successfully.

    For help, contact your campus Support Center.

  2. Click Your devices & settings.
  3. Under "Management", select or deselect the "USE TWO-STEP LOGIN:" toggle to use Two-Step Login (Duo) every time you log into CAS.
    Note:
    If having this setting enabled is required for you, the toggle will display a lock icon.
