How to use Security Keys to protect your Apple ID on your iPhone

The process shouldn’t take more than a couple of minutes.

Now that you’re done, make sure to store your keys in separate places (I have one in use and another as backup, but you might want one for home and another for the office, or whatever works for you).  

Don’t put both in the same place — such as on the same keyring. That way if you lose one, you’ll lose both.
