[SOLVED] udev rules for U2F FIDO Plug-up key

I just received a cheap U2F FIDO key (http://www.amazon.com/Plug-up-Internati … 00OGPO3ZS/) but couldn't use it under Chrome 38. I had to add the following rule to /etc/udev/rules.d/45-u2f.rules

SUBSYSTEM=="hidraw", MODE="0666", ATTRS{idVendor}=="2581", ATTRS{idProduct}=="f1d0"

and then issued a

# sudo udevadm trigger

Should work with other vendors assuming you change the idVendor and idProduct.

Have fun!

Was thinking about the same device, what are you thoughts on it so far? I was mostly concerned with the price and how that translated to the quality, or lack thereof.

Was thinking about the same device, what are you thoughts on it so far? I was mostly concerned with the price and how that translated to the quality, or lack thereof.

The device for which I sent a link for is cheap one and when you receive it actually looks cheap but does the job. Initially I thought I needed to install the FIDO U2F Chrome extension https://chrome.google.com/webstore/deta … ionmgcdmne but it works just fine without it assuming you are using Chrome or Chromium 38+ and the above udev rule on ArchLinux (not required on Windows and MAC OS).

Use case is fairly limited so far since it can only be used on Google account. I tried to use this Plug-Up U2F dongle on Yubico U2F demo page http://demo.yubico.com/start/u2f/neo but it doesn't work and thus even with the FIDO U2F Chrome extension...Weird since I thought all U2F will all be compatible. Since the protocol is open I hope other use cases will arise such as more major supported websites, easy integration in existing frameworks such as Wordpress, Roundcube... but also alternative uses such as 2nd factor authentication for disk encryption (LUKS).

Hey alphazo,

Just wanted to thank you for you info.  I also got the same U2F FIDO key and was trying to find out why my laptop was not recognizing it.

From my very short time playing with it, it seems that it works fine.  I am wondering though how widely accepted the key will be in other machines (internet cafes, a friends computer etc)  If I need to have sudo access to make the key recognizable by the system, it kinda makes it useless.

Time will tell.

Thanks again!
