  • USB or NFC usage - Insert the YubiKey into the USB port, or use the YubiKey with NFC with a mobile phone that is NFC-enabled or a desktop NFC reader to store your credential on the YubiKey

  • Easy Setup - QR codes available from the services you wish to protect with strong authentication

  • User Presence - Require a touch on the YubiKey sensor to generate new codes for sensitive accounts
