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

Important:
Logins for all IU students, faculty, staff, retirees, affiliates, and those with Academic (ACNP) status require Two-Step Login (Duo), including group or departmental accounts (but not IU Guest 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.

Two-Step login (Duo) 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.
