What is Two-Step Login (Duo) and how does it work?
As of February 2, 2017, CAS logins for all IU faculty, staff, student employees, retirees, and affiliates require Two-Step Login (Duo). Others at IU (those with academic no-pay or simply a student role), can opt into the Two-Step security feature. For more, see About using Two-Step Login (Duo) every time I log into CAS.
Additionally, connecting to IU's SSL VPN (Pulse Secure or Network Connect) requires Two-Step Login for everyone, regardless of your university status.
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:
- Entering your username and passphrase.
- 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 Getting started with Two-Step Login (Duo) at IU.
