How to check my card’s authentikey?

The authentikey is a public/private elliptic curve keypair that is unique per Seedkeeper device (and Satochip) and that can be used to authenticate a device and initiate a communication with it.
You can check your card’s authentikey by following these steps:

1. Grab your Seedkeeper or Satochip card and plug it in your card reader.
2. Launch the SeedkeeperTool (see the “Download” section).
3. Click on “About”.
4. There you can see the card’s authentikey.
