***iOS/iPadOS is only able to communicate with the YubiKey's OATH application (required for Yubico Authenticator functionality) via NFC and Lightning. ** iOS/iPadOS 13.3 and Safari are required to leverage native support for WebAuthn.

In any case, we would advise you to try an adapter from a reliable, trust-worthy brand. *Please note that we do not recommend using adapters, but do understand that adapters are sometimes unavoidable. Note: Yubico Authenticator does not support this option** if you're not running iPadOS 16.1 and the latest version of the Yubico Authenticator*** Any YubiKey model can be plugged either directly into an iOS/iPadOS device or using an adapter* to take advantage of both the OTP functionality, as well as WebAuthn*.The YubiKey 5 NFC, YubiKey NEO, and Security Key NFC can be used over NFC on NFC-enabled iPhones.**.The YubiKey 5Ci can connect directly to an iOS/iPadOS device via a Lightning connector.Yubico does not maintain setup documentation for third party products or services.ĭepending on the iOS/iPadOS hardware as well as the YubiKey or Security Key model, there are three methods for using a YubiKey with iOS/iPadOS. For information such as can I log into my service on iOS/iPadOS, consult the Works with YubiKey Catalog or reach out to the service directly for more information. So if the yubico breaks, I can use the cheapo backup until I receive the replacement yubico key.Note: This article covers basic YubiKey / Security Key use on iOS and iPadOS. I got this and a cheapo but we'll functioning basic key for ten bucks. Next.note you should have 2 keys for backup, but they don't have to be the same, not do you need two of these 5 series yubico. So the key I got was on a firmware from about a year ago and is missing a few profiles added to some security protocols I don't use. But they can't be updated in the field due to security issues. This key, like others you'll find for sale away from the manufacturer may have older key firmware with a bug or improperly implemented feature.

Yubico, a company that drives the above standards extends those to additional protocols, a yubico authenticator app that works in conjunction with the key. Fido, fido2 and u2f are pretty well covered. Other than standard two factor logins with a key. I won't explain what it does, I presume folks know it's for higher login/data access above and beyond passwords. Good key, buy them on eBay to save $ but be advised.
