iOS: Connect to the Stanford VPN with a Cardinal Key

Please note that as of March 6, 2025, this method has been deprecated and will no longer function. Stay tuned for updated instructions on how to connect to Stanford's VPN using Cardinal Key on iOS.

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 stanford.edu 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.
