Using U2F Token on Linux (udev)

Devices using the HID class for U2F tokens are initially only accessible to root users on Linux. To fix this, a udev rule must be added.

Open /etc/udev/rules.d/70-u2f.rules Add the following:

KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="8acf", TAG+="uaccess"

Save and run:

sudo udevadm trigger
