Protect Your SAS Accounts with Two-Step Verification

  • Faculty & Staff
  • Students & Alumni

 password + proof = access


***Duo Two-Step verification system is being upgraded to the Duo Universal Prompt on November 14, 2023. Click here for more information.***


The Two-Step Verification service will drastically reduce the risk of compromised data and nefarious use of your accounts. Because a login from a new computer requires not just a password but a verification code that is delivered to your smartphone it is much harder for malicious, unauthorized users to gain access.

Please see below for instructions on how to set up Two-Step for various accounts here at Penn.

If you are not already, we strongly suggest that you enroll in Duo Push. Duo Push is the most convenient method of Two-Step verification: the user receives a popup message on their phone much like in the image above. They would simply press "approve" instead of needing to enter any numbers.  Click here for setting up Duo Push for the first time.  Click here for setting up Duo Push on a replaced phone.
