The YubiKey can be connected to older iPad or iPhone devices using Apple’s Camera Connection Kit (iPhone 4) or with a Lightning to USB Camera Adapter (iPhone 5). Core YubiKey functions (Yubico OTP, Static Password, and so on) are supported, however CCID functions are not.
NOTE: iPads after the iPad 3 (iPad 4, iPad Air, and so on) will not work properly with the YubiKey. This is due to changes in the Apple firmware over which we have no control. If iPad compatibility is critical for you, consider options other than the YubiKey.
How to start your YubiKey
The YubiKey has to be connected to the dock of the iPad using Apple’s Camera Connection kit which provides a standard USB port.
1. Insert your YubiKey in the Apple Camera Connection Kit with the USB-contact facing upward. Connect the Apple Camera Connection Kit with your iPad, wait until the green light in the touch button is steady, indicating that iPad has detected the device.
2. A dialog box appears the first time the YubiKey is plugged into the iPad with the message “The connected device is not supported”. To cancel the dialog box, click OK.
3. Open Safari and browse to yubico.com/start and touch the YubiKey entry field.
4. Place your fingertip on the touch button of the YubiKey, hold for a second, then release. The YubiKey sends your One-Time Passcode to the server. This procedure only needs to be done once to use the YubiKey on your iPad.
