Yubikey for OTP password manager 2FA only ...with Q4.5 sys-usb please

[anon]

Hello, using Q4.5 I have been reading the various yubikey howto
problem-solving, but remain confused what to expect for my use of the
Yubikey, which is, I believe OTP  for  2FA  for lastpass

On my desktop I have Q3.2 and no sys-usb   and I have NOT had to install
any particular packages in dom0 or the Fed26 template etc.

in Q4.5 I do note the widget to attach the Yubikey to the AppVM
example:  EmailVM , and I see it attached with lspci in the AppVM ,
using the widget, however it is nonfunctional.


Typically, the Yubikey at times asks you to detach and reattach it,
which probably in hindsight is not a good idea, as after doing that the
widget will no longer allow any detaching.


when I go into dom0 and do qvm-device attach email sys-usb:2-1.1 at
current it is freezing and I can't Ctl+c out of the command ....

I have 8gb Ram in an i7 thinkpad here, and for some reason I can't even
get sys-usb to launch a Terminal, guess I'll be rebooting , maybe an SSD
in the future is going to make Q4.5 usable ? (sorry added some
commentary here) :O


I believe at one point it told me the qubes usb proxy was not installed,
then I went and tried to dnf install qubes proxy in the sys-usb and it
said it *Was already installed.


I find sys-usb the most difficult aspect of Qubes use, on Q3.2 after
locking myself out I gave up on sys-usb ... and don't feel for my
purposes a huge worry re: security  ......can I do the same in Q4  or
....... what do you suggest ..
