I have the same issue, my Yubikey is the yibikey neo 4 model, it does
support U2F. after installing Ubuntu 18.04.01 I followed yubico's
instructions:
https://support.yubico.com/support/solutions/articles/15000006449-using-
your-u2f-yubikey-with-linux

which means I have a udev rule for the device, but dmesg was still
mapping to snap.chromium. At this point the U2F seemed to wait for input
until timeout, whereas the key's LED would flash like if it were in
process of system recognition indefinitelly (as seen from dmesg, it
seems chromium it continously attempting to read the device, but there
are permission restrictions).

dmesg:

I have attempted as instructed in #9, the results are as described in
#4: the U2F solicitors (github, gmail) will report "somethig whent
wrong" as soon as the key is inserted. Thus it seems the issue got
worse. BTW how do I get back to the default channel?

Title:
  [snap] U2F doesn't work with yubikey

Status in chromium-browser package in Ubuntu:
  Confirmed

Bug description:
  (initially reported by Daniel at https://forum.snapcraft.io/t/call-
  for-testing-chromium-62-0-3202-62/2569/50)

    « U2F (Universal 2nd Factor) isn’t working when signing into my
  gmail account trying to use my yubikey. This is a USB device which
  IIRC chromium needs bidirectional communication with. »

  This requires investigation, but the yubikey I have is too old and
  doesn't support U2F.
