Yubikey fails after update



When I used the snap installation of Brave, I could use Yubikey to sign into google, twitter and facebook. After update to version 0.59.35 Chromium: 72.0.3626.81 (Official Build) (64-bit) I get this error message:

To disable the flag, completely shut down and relaunch chromium from the command line with the following flag set:

Reference for developers:


Hello, sorry about this. The snap isn’t officially supported.
