![]() ![]() The Universal 2 nd Factor (U2F) protocol was primarily intended to be a simple protocol and used as a second factor authentication scheme in addition to the first factor (the user's password) while.For the sake of expediency, the FIDO Alliance standardized both protocols to deliver mostly similar benefits: The first two protocols came about when, six years ago, two independent efforts to re-introduce 2 strong authentication for web applications joined together to form the FIDO Alliance. Read our FIDO 201 article to learn how FIDO2-based authentication can be deployed using StrongKey's PKI2FIDO web application, and move beyond PKI or replace PIV authentication.įIDO consists of three protocols for strong authentication 1 to web applications: Universal 2 nd Factor (U2F), Universal Authentication Framework (UAF), and FIDO2 or WebAuthn. I swapped over to the Mac to continue, and had better luck.To learn more about the Alliance, read our FIDO 101 article. Apple's process signed me out of the unsupported devices or devices I had not logged into, but then the Security Keys setup would not progress. I had to go through this process, and I want to note that it didn't quite work properly (which is not the YubiKey's fault). Older devices won't support Security Keys at all. Before you can add a Security Key, you need to sign out of all inactive devices, which includes devices that you have not used in the last 90 days. On an iOS device or Mac, Security Keys can be enabled through the Password and Security section of the Settings app. ![]() You're going to want to store the Security Keys in two separate locations. The reason for this is because if you lose your physical security key, if you don't have another in a safe place, you're going to lose access to your Apple ID. Apple requires dual security keys for redundancy purposes, and Yubico recommends a pair as well. Note that whatever security key product you pick, you have to have two, not just one. Security Keys can be set up on the iPhone, iPad, or Mac. ![]()
