Post subject:  Combine challenge-response function with a static password?

Hi all,

Is it possible to combine challenge-response function with a static password?

Say I put a Yubikey Nano in a usb slot, and want the computer to automatically log me in to the associated user account if the yubikey is present, but ask me for the username/password if the yubikey is not present, and if I change the user account password every now and then, I just update the static password on the yubikey so the automation would still work.
The yubikey must be "challenged" automatically for this to work.

Is this possible combined with a static password?

I tried to search the forums for "challenge" to see if this was asked previously, but the closest topic I found was the following:
"Is it possible to fetch the static password?"

Hello,

No, this is not possible

ok - thanks for the reply.

Would you say this is a more profound technical impossibility when it comes to the nature of Challenge-Response, or could it technically be possible to make such a function, hence possible for Yubikey to contemplate on such a new feature in the future?
