About Two-Step Login (Duo) at IU

You can now manage your Two-Step Login (Duo) settings in the Security Center. On November 1, the Security Center will replace the Two-Step Login site as the place to access your Two-Step devices and settings. For details about how the Security Center can help you stay secure at IU, see IU Security Center.
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).

To lessen the number of times you need to complete a Two-Step Login with Duo, select Remember me for 7 days when completing a Two-Step login. This will keep you from having to Two-Step for CAS logins for seven days in the browser from which you initiated your login.

Two-Step Login (Duo) provides an additional layer of security when you log into some IU systems. Two-Step Login, also known as two-factor authentication, helps protect sensitive data and guard against increasingly sophisticated email and online scams (e.g., phishing attacks) that can leave you vulnerable to identity theft. IU has partnered with Duo to provide this service.

Like similar services offered by Google and Facebook, you log in by:

  1. Entering your username and passphrase.
  2. Confirming your login with an enrolled device.

UITS recommends using the Duo Mobile app on your smartphone or tablet, but if you don't have such a device, regular cell phones, landlines, Google Voice phone number, and U2F tokens are also supported. Single-button hardware tokens (SBHTs) are also being made available.

For step-by-step instructions for all options, see Get started with Two-Step Login (Duo) at IU.
