How Do I: Setup Duo Mobile on a Phone or Tablet?

Two factor authentication provides a secondary security check when accessing sensitive information and resources. We require both a password and an secondary approval to log in to the VPN. This prevents someone from accessing resources they shouldn't if a password is compromised. Here is a comprehensive guide to what services or websites support two-factor authentication.

CalArts uses a service called Duo Mobile to facilitate two-factor authentication. You can use Duo Mobile to secure Google, Amazon, and a bunch of other accounts, but for this guide we're focusing on Skylight.

  • Use a computer (Firefox or Chrome) for the first 6 steps, don't use a mobile device to setup Duo Mobile.
  • If cookies are disabled you were receive an error (at which point just send us a note and we'll be happy to help).
  • It would be best to download Duo Mobile on your device before you start: iPhone/iPad, Android
