These steps are valid for iOS devices (iPad or iPhones) only. For information on how to get started using your YubiKey on Mac OS devices, see How To Get Started with YubiKey on Mac OSes.

This article applies to YubiKey devices only (FIDO U2F Security Key by Yubico cannot be used on iOS devices at this time).

The YubiKey can be connected to older iPad or iPhone devices (such as iPad 3 or iPhone 4 and older) using Apple’s Camera Connection Kit, or newer devices (such as iPad 4 or iPhone 5) using a Lightning-to-USB Camera Adapter. Only core YubiKey functions (Yubico OTP, Static Password, and OATH-HOTP) are supported. This means that U2F, OATH-TOTP, and challenge-response are not supported, as well as any CCID-related functions.

How to get started using your YubiKey

  1. Do one of the following:
    • Insert your YubiKey in the Apple Camera Connection Kit with the USB-contact facing upward, and then connect kit with your iOS device. 
    • Insert your YubiKey in the Lightning-to-USB Camera Adapter with the USB-contact facing upward, and then connect the adapter to your iOS device.
  2. Wait until the green light in the touch button is blinking, indicating that iOS device has detected the YubiKey.
    • If a dialog box appears the first time the YubiKey is plugged into your device with the message “The connected device is not supported”, simply click OK to exit the dialog box.
  3. Open Safari and browse to
  4. Click in the YubiKey field, and then touch your YubiKey. The YubiKey sends your One-Time Passcode to the server.

Note: If the One-Time Password fails (and begins with a capital letter), check to be sure you have turned off auto-capitalization in the iOS preferences. This setting is turned on by default. To turn it off, go to Settings > General > Keyboards, and slide the setting to turn off Auto-Capitalization).

You need to do these steps only once for each new YubiKey you want to use on your iOS device.
