8 The idea behind one-time-passwords is that they can, well, only be used once. After authenticating with an OTP the only way to log in again is to calculate the next one in the sequence and use that. The only (practical) way to generate this is by inserting the YubiKey and pressing its button. Acting as a USB keyboard it then "types" the OTP into the password prompt of your XMPP client. 8 The idea behind one-time-passwords is that they can, well, only be used once.
