Unlocking PC with NFC implant


I was wondering if anyone has had any luck in getting their PC to unlock with these implants ?

Both in a windows domain joined machine and home.

If anyone has a list of kit or info it would be very appreciated.

Also can you use the one implant to unlock your phone and your PC ?

Kind Regards

I personally use an ACR122U for computer login. There are two software packages that work well for Windows login:

ISLOG Community Edition
EIDAuthenticate & NFC Connector

If you’re wanting to use the xNT or flexNT for PC login, then I’d try the first option. It’s free and works well enough. The second option is not free, and possibly a bit less user friendly, but it will become useful in the near future with the release of VivoKey. Also, EIDAuthenticate needs a REG file to be loaded so the PC/SC system recognizes the xNT / flexNT as usable for authentication. Unzip and execute these REG files to register the proper links for x-series tags:

Vivo key looks awesome !

Might just get one implant until that’s released .

Will check those out thank you.

Can you easily just clone other tags into the implant with a phone or is it worth investing on a proper reader ?

Instead of replying about cloning, I wrote this post… hopefully it makes sense.

That’s perfect thank you

I couldn’t get this to work and was originally asking for help, but managed to get this to work finally so here’s a quick guide for those who run into this in the future and just want to login to windows from their own PC and don’t have a full AD setup.

  1. Install the driver for your ACR122U (I’m not sure if this is critical, but it seemed like the right thing to do)
  2. Install the FREE version of NFC Connector it should be called NFC-CSP-Light (the Enterprise version is kind of a dick and doesn’t play nice with the reg edit provided above and I couldn’t manage to get it to work with it’s own registration software either. That might be because I don’t know what I’m doing though, so if you can figure that out let me know.)
  3. Run the reg edit from above
  4. Open the NFC CSP Smart Card Manager app and add a certificate for your implant
  5. Now install EIDAuthenticate and associate the certificate from your implant with your account in the configuration portion of the installer.
  6. Enjoy sweet victory and login with your hand. Unfortunately yes, you will still have to press enter on the PIN screen even if you don’t use a PIN.

alternatively, you could turn off the password for your account (less secure) or use this as a two step authentication (more secure), you could use some form of Arduino, a relay, and a rc552 reader and wire it up to your front panel port on your motherboard. here’s some links,

I primarily use Linux, and wrote my own scripts to log in, and lock/unlock sessions (https://github.com/Giraut/nfcutils). Under Windows, I use Rohos Logon Key for machines on a domain (not free) and ISLOG Logon NFC Community for standalone machines (free).

I posted a slightly more detailed writeup of what I have going, including a couple of videos, in this thread on the biohack.me forum: https://forum.biohack.me/index.php?p=/discussion/2715

(I hope it’s cool to link to another forum. Otherwise, my apologies and feel free to delete my post…)


Free information exchange is what forums are about :wink:

So, for the NExT they have an automatic code that gets typed out when scanned. You could just change the password on your PC to match. I took apart the USB reader from dangerous things and hard wired it in and mounted it inside my Chromebook to the left of my touchpad. It picks up the tag through the plastic no issues and automatically enters the code and logs in all with one scan. Simple solution if you don’t want to get into the nitty and gritty of trying to encrypt any further.


I had the same idea and had it on my list of things to do, glad somebody has done it successfully.
did you wire directly to the usb port internally? if so does it render the port unusable externally, does it cause any COM port conflict or similar? (the reason/ excuse I haven’t tried it yet)

I also considered placing the reader behind the screen,

  1. Open screen
  2. hand swipe behind
  3. Access granted :keyboard: :old_key:

but I foresee the cable run being the tricky part even with ribbon cable?
