Yes. It does exist.

It does. Something like:

rofl:~ # xauth info
Authority file:       /run/sddm/{e38ebf58-e9d4-453d-8562-d357d7ab5238}
File new:             no
File locked:          no
Number of entries:    1
Changes honored:      yes
Changes made:         no
Current input:        (argv):1

All fine, I think.
