All the YubiKeys are doing is shifting the storage of the secret tokens to generate the codes to hardware instead of virtually. The codes are displayed via the Yubico Authenticator app, which if you’ve used Google Authenticator, looks & works pretty much identically. When you turn that key by plugging it into your computer or tapping it against your phone it unlocks access to the special one-time codes stored on it. Using the simplest of simple explanations these guys act as a key. In fact SMS is probably the worst way and has led to many of the major security breaches in the past decade.Įnter Yubico and the YubiKey. Those codes are only valid for a short amount of time and that extra layer of security is great, but they can also be easily accessed by hackers, especially if you receive them via email or SMS. To explain that we’ll need to take about two-factor authentication or 2FA as it’s more widely known and those annoying websites that send us codes to type in after our passwords via a text, email or apps like Google Authenticator and Authy.
I’ll do my best to explain what they are and why you should consider using them to tighten up your online security & safety. Now if you have no idea what these are, don’t be afraid you’re definitely not alone. At this time, there is no way to use Yubico Authenticator on these iPads, as they do not support NFC.Today we’re taking a look at the YubiKey 5 series from Yubico in particular the YubiKey 5C NFC and the YubiKey 5Ci. Read/write is possible over NFC due to Apple's recent expansion, and via Lightning due to the YubiKey 5Ci's MFi certification, but not using other connection methods, namely USB-C, which has replaced the Lightning connector on third-generation and later iPad Pros. Since the one-time passwords generated by Yubico Authenticator are time-based, and the YubiKey does not have the ability to track time (due to its lack of a battery), proper functionality requires iOS/iPadOS being able to both write to and read from the YubiKey (it sends the YubiKey the current time and receives the one-time password). **iOS/iPadOS is only able to communicate with the YubiKey's OATH application, which is required for Yubico Authenticator functionality, via NFC and Lightning. Note: Yubico Authenticator does not support this option.** Any YubiKey model can be plugged either directly into an iOS/iPadOS device or using a compatible adapter to take advantage of both the OTP functionality, as well as WebAuthn*.
