[nitishagar] We have reports from user experiencing issues with yubikey usage for privileged mode access with Etcher. The current workaround is to unplug the Yubikey and enter password manually which lets the process move along.

One of the user's experience with the issue:

the system promps for "balenaEtcher needs privileged access in order to flash disks. Type your password to allow this.", neither the system passord, the yubikey password or touching the yubikey will get past this prompt. In fact, after several attempts, the yubikey will get disabled and causes a convoluted process to reactivate it.
