One way to increase the security of computer systems is to use multiple factors for authentication. Typically, this will be two factors and follows the pattern of authenticating with a "knowledge" factor, which is something you know, like a password, and a "possession" factor, which is something that you have. The latter is typically a key or one time password often generated by a device. In the near future we will be implementing a two factor authentication system for the HPC resources. The technology that has been chosen is called Duo from Duo Security. This is the same technology that was deployed for the University of Iowa Employee Self Service site.

We are currently kicking off a pilot of two factor authentication. If all goes well in the pilot then all HPC users will be required to authenticate with two factor authentication. More information will be coming shortly. If you would like to participate in the pilot please send a note to HPC-Sysadmins. If you are part of the pilot please provide feedback and problem reports. |
In order to use Duo on the HPC systems you must enroll in the Duo service and register a device. The most convenient method for managing Duo, particularly on the HPC systems, is via Duo's app for smartphones. There is support for all, or most, types of smart phones; see this page for more information. Please see the following page for setting up a smart phone for Duo:
