When you send the signed challenge back to the server, it uses the public key to decrypt the signature (thus verifying it was you that signed the challenge) and then verifies that the hash of the challenge is correct (thus verifying you signed what the server sent and not some other string of bytes).

A digital signature is a cryptographic hash of the contents of the message being signed (in this case, the server challenge), which is then encrypted with your private key.

You unlock the private key on your local device (for iPhone, using biometrics), and sign the challenge locally. In the future, when you log in, the website sends a challenge, which is just a random string of bytes. When you are signing up, your local device generates the keys, sends the public key to the service you are accessing (this is effectively your 'password', but much more secure), and stores the private key in secure storage (so on an iPhone, the Secure Enclave). The public key can decrypt anything encrypted by the private key and vice-versa, but they cannot decrypt things they themselves encrypt without the other key. The public key is easily derived from the private key, but the private key cannot be derived from the public key. With PKC, there are always two related keys: A private key, and a public key. The root of this technology is public-key cryptography. Sure! This happens to be an area of interest for me.

Would website devs need to drastically change how they code websites or would the phone handle the translation between the website asking for a password and the user just being able to scan their face?

'Working with the industry to establish new, more secure sign-in methods that offer better protection and eliminate the vulnerabilities of passwords is central to our commitment to building products that offer maximum security and a transparent user experience - all with the goal of keeping users' personal information safe,' said Kurt Knight, Apple's Senior Director of Platform Product Marketing, in a press release.Ĭan someone explain the security of this? Obviously I doubt that my facial data would be shared with the website, but how does it remain secure? These new capabilities are expected to become available across Apple, Google, and Microsoft platforms over the coming year, the announcement said. Enable users to use FIDO authentication on their mobile device to sign in to an app or website on a nearby device, regardless of the OS platform or browser they are running. Allow users to automatically access their FIDO sign-in credentials (referred to by some as a 'passkey') on many of their devices, even new ones, without having to reenroll every account.Ģ. The new approach is described as 'radically more secure' compared to passwords and legacy multi-factor technologies, such as one-time passcodes sent over SMS.Īpple, Google, and Microsoft already support FIDO Alliance standards across their platforms, but expanded support will give users two new capabilities for more seamless and secure passwordless sign-ins, as outlined in the announcement:ġ. Instead of entering a password, users will sign in through the same action that they take multiple times each day to unlock their devices, such as Face ID on the iPhone. The expanded standards-based capabilities will give websites and apps the ability to offer an end-to-end passwordless sign-in option, according to the announcement. Apple, Google, and Microsoft today announced plans to expand support for a passwordless sign-in standard created by the FIDO Alliance and the World Wide Web Consortium (W3C), promising a faster, easier, and more secure sign‑in process.
