Apologies if this has been covered before. I just set up two YubiKey 5Ci’s on my iCloud and then realised I wanted PINs on them. Is it okay to set up PINs after I’ve added the keys to my iCloud? I understand the PIN is separate to iCloud so then how does iCloud recognise the keys later when you need the PIN to use the key? (Sorry if that doesn’t make sense, I just want to make sure I don’t get locked out of my iCloud and I’m a bit technologically challenged 🤦‍♀️) Thanks so much!
