FIDO2 Token Management Tool Manual

version 0.2

Overview

The FIDO2 Token Management Tool (fido2-manage.exe) is a command-line wrapper tool designed to interact with the libfido2 tool, providing a convenient way to perform various operations related to FIDO2 tokens.
Starting from v0.2 this tool supports managing FIDO2.1 devices over NFC transport. Only one NFC reader with a FIDO2.1 device should be present in the system (the tool will only attempt to enumerate/read the first one, appearing as pcsc://slot0). Please note that NFC stability depends on the precise positioning of the NFC card antenna overlapping with the reader's reading area. NFC functionality was tested only using NFC Reader devices provided by Token2.

Prerequisites

Ensure that libfido2.exe is present in the same directory as the tool.
PowerShell must be installed on your system.

Usage

Running the tool

Open command prompt as administrator and navigate to the directory containing the tool. Execute the tool by running the following command:

.\fido2-manage.exe [parameters]

-list: List available devices. Please note that if you plug in only one FIDO2 device, the device number to be used is always 1

```
.\fido2-manage.exe -device 1 -changePIN
