An essential notice: Apple doesn’t make it crystal clear of their doc About Safety Keys for Apple ID that safety keys exchange the corporate sending you six-digit codes by way of trusted gadgets or trusted cellphone numbers. Apple notes, “A safety key can act because the second piece of knowledge, as an alternative of the six-digit verification code that’s usually used.” Nonetheless, in testing, with safety keys enabled, the code-based technique can’t be used. Disabling safety keys reverts to codes.

The way it works behind the scenes: a pair of keys

The safety keys use public-key cryptography, one thing you might need heard about earlier than. All of the complexity is hidden from you as a person–one of many intents of the FIDO Alliance. In public-key cryptography, everytime you want a brand new identification–reminiscent of a key used for proving your possession of an account at a web site–an working system or different software program randomly generates a robust secret and derives a public key and a personal key from them, that are intertwined mathematically.

The non-public key’s stored strictly secret by your software program or {hardware}. Usually, it by no means leaves your gadget and should not even be instantly accessible by you, its proprietor. The general public key, nonetheless, may be freely shared. Different events who possess your public key can use it each to encrypt messages that solely you possibly can learn, decrypting them together with your non-public key; and to confirm {that a} doc or different message you ship them is legitimate. Your gadget can cryptographically “signal” a message with the non-public key, and anybody with the general public key may be assured that it was signed solely by you.

With a {hardware} safety key and the FIDO protocols, you enrolled at a web site by signing up by way of your account settings to make use of two-factor authentication with a {hardware} key. Your {hardware} key creates the distinctive secret for the positioning and transmits the general public key to the positioning, which shops it together with your account info.

When logging in later, right here’s what occurs:

• The location points a problem utilizing the general public key that it beforehand saved for you.
• Your working system communicates with the safety key to have it generate a response, signing the problem with the non-public key for that web site. (If the general public key the web site supplied doesn’t match, it signifies a doable phishing try, and the method fails.)
• Your working system sends again the signed problem.
• The web site makes use of the saved public key to validate it’s you. If that’s the case, you’re logged in.

Whereas this would possibly all sound fussy, you aren’t concerned in any of the particulars. As a substitute, to make use of a safety key, you insert it when prompted right into a USB Kind-A, USB-C, or Lightning jack and press, contact, or faucet it. (You may depart it inserted and set off it every time prompted by your gadget or a web site.) With a touchless NFC safety key, you deliver it close to a tool that helps NFC. The safety key then generates the suitable info on the time of enrollment or while you log again in later.
