Install a Cardinal Key on an iOS Device

Cardinal Keys simplify your login experience by reducing or eliminating the need to use your SUNet ID and password for web-based logins and VPN connections.

Cardinal Keys are installed on a per-device basis and are deployed using Cloudpath software. A Cardinal Key should not be installed on shared devices, and the same Cardinal Key should not be used on multiple devices.


  • iOS 10 or later
  • Installation must be done in Safari for iOS devices
  • Device must be managed by Jamf (Mobile Device Management)
  • Faculty, staff, students, and affiliates: device must be compliant, without an exception on file, in MyDevices
