Yes and no. It is similar to using a YubiKey for USB-A ports plugged in using an “on the go” (OTG) cable into the micro USB port of an Android device. When you insert your YubiKey 4C into the USB-C port on your Android devices, only the basic one-time password (OTP) button press functionality works natively.

The following functionalities are not supported using the YubiKey 4C (or over any USB connection) on Android devices:

  • U2F
  • PIV
  • Yubico Authenticator

OpenPGP is supported with the use of a third-party application, OpenKeyChain (available from Google Play).

It is also important to note that while your YubiKey 4C is plugged in to your Android device, the on screen keyboard will no longer be accessible in Android until your remove your YubiKey.
