PS Batch YubiKey Config is a YubiKey batch configuration tool for the YubiKey Manager, written in Powershell.

• Simple to use! Quickly program entire trays worth of YubiKeys with YubiOTP, HOTP or TOTP seeds
• Script exports a well configured CSV file full of seed values for easy import into Okta/Duo/Azure/etc.
• Script is completely offline and relies on no dependancies other than Yubico's own YubiKey Manager software.
• Friendly command line UI shows you how many YubiKeys you've programmed during your batch programming session
• Full support for defining an administrative access code for each YubiKey, preventing users from reprogramming their devices

• Any operating system capable of running Powershell (Windows, Linux, macOS)
• Latest version of the YubiKey Manager

• As a general rule of thumb, never run Powershell scripts that you do not understand. Always feel free to review this script for yourself and ask questions in the form of a GitHub Issue

• For safety, I recommend that you run this script on a machine that is disconnected from your network, taking care to delete the CSV file once you are done uploading it. This script does not require network access.

• For clarity on Powershell's default script execution policies, please review the Microsoft documentation .

1. Ensure the YubiKey Manager is installed.
2. Launch PS_Batch_YubiKey_Config.ps1
3. Click Enter on the keyboard when prompted to select a location for the CSV file which will hold the OTP seeds.
4. Choose whether or not to set an access code to the YubiKeys. (If Yes, The access code will be set to the serial number of the YubiKeys.)
5. Insert the first YubiKey to program and press the [Enter] key to begin batch programming.
6. To finish programming, simply press Control C or close the Powershell window. Throughout the session, the script will append to the CSV file that you defined.
7. Upload the CSV file to the desired platform, delete the CSV file from your machine.

1. Ensure the YubiKey Manager is installed.
2. Launch the .ps1 file with the hotp flag attached. PS_Batch_YubiKey_Config.ps1 -hotp
3. Click Enter on the keyboard when prompted to select a location for the CSV file which will hold the OTP seeds.
4. Choose whether or not to set an access code to the YubiKeys. The access code will be set to the serial number of the YubiKeys.

1. After programming the YubiKeys for TOTP with Microsoft Azure, the CSV file will still lack your user's UPN information. Proceed accordingly.

slot2 - YubiKeys will be programmed in their second slot rather than the default slot 1.

hotp - YubiKeys will be programmed with HOTP seeds rather than the default YubiOTP

totp - YubiKeys will be programmed with TOTP seeds. (User must use Yubico Authenticator app to generate TOTPs!)

ignoreduplicates - Script will not check if a YubiKey has already been programmed during the session

whatif - Script will not program YubiKeys and will instead write to the defined CSV file with dummy data.
