Does TOTP use up a slot? Ideally I would like to have my yubikey set up to have tradition OATH/TOTP, Yubikey OPT and then a static password. Is it possible to set it up this way? I'm pretty sure my first slot is already set up to act as OATH/TOTP and then I've set up the second slot to be Yubico OTP. Does this mean that I can't have a static password?
