iOS: Connect to the Stanford VPN with a Cardinal Key

You can connect to the Stanford VPN using a Cardinal Key on your device to authenticate. This eliminates the need to enter your SUNet ID, password, and authentication method for two-step authentication.

The VPN connection is split-tunnel. This means that all traffic goes through the VPN connection but non-Stanford traffic flows flows normally on an unencrypted internet connection.

Before you begin

Make sure you have a Cardinal Key for iOS installed on your device.
