otp slotDuring manufacturing, YubiKeys are confured with a Yubico OTP (in the short-press slot), and the OTP secrets are uploaded to YubiCloud. This enables out-of-the-box OTP authentication.Slots confured with a Yubico OTP, OATH HOTP, or static password are activated by touching the YubiKey. The duration of touch determines which slot is used.
