I recently bought a NitroKey Pro and wanted to enable it with Google's 2FA.
I logged into myaccount.google.com and chose the "Google Authenticator" option. Instead of scanning the bar-code, I copied the base32 secret code provided.
Then from the Nitrokey tray app, I created a new slot for Google and pasted in the secret code. You can see the settings I've configured in the screenshot below.
After creating this new TOTP, I used the Nitrokey app to generate a verification code.
However, when I go to paste it into the browser window, Google rejects the 6-digit code generated by Nitrokey.
Any help would be appreciated,
