iCloud Hardware Token

I was trying to setup my Onlykey as a hardware token for iCloud. It recognized it and made the OK blink blue, then I tapped the button, it then asked for a pin. What do I enter here?

If it is prompting you to set a PIN you would need to set up a FIDO2 pin, if it is prompting to provide the FIDO2 PIN this would be a PIN you set up previously. The FIDO2 pin is separate from the OnlyKey PIN that is used to unlock OnlyKey.

Ok, I think it was prompting me for a pin that I set up long enough ago that I didn’t remember it. I just reset all creds and set a new pin and that worked. Thanks for clarifying!
