FIDO2パスキー管理がiOSではできないことを明記してほしい

Security Key C NFCを購入し、iPhone版Yubico Authenticatorをインストールしました。

App Storeの説明ではNFCによるYubiKeyの利用や「Hardware Security」が紹介されているため、iPhoneでもNFCを使ってYubiKey内のFIDO2パスキーを確認・管理できるものと思っていました。

しかし、実際にはiOS版ではFIDO2パスキーの一覧表示・管理には対応しておらず、同じYubico AuthenticatorでもDesktop版やAndroid版でのみ利用できる機能でした。

最初にNFCでSecurity Key C NFCを読み取った際には「このYubiKeyには、要求された機能がないか、無効になっています」と表示されたため、製品の故障や誤配送まで疑ってしまいました。

Mac版Yubico Authenticatorでは正常に認識され、FIDO2パスキーの一覧や使用数(8/100)も確認できました。また、Yubico公式のGenuine Verificationでも正規品・Firmware 5.8.0として正常に確認できています。

iPhoneでYubiKeyをNFC認証に使用できること自体には満足しています。

ただし、iOS版ではFIDO2パスキーの一覧表示・管理ができないことを、App Storeの説明でもう少し明確にしてほしいです。現在の説明やスクリーンショットでは、iPhone版でもDesktop版やAndroid版と同様のパスキー管理ができると誤解しやすいと思います。

NFC YubiKey Authenticator Issue

I’m having issues with NFC YubiKeys. I can’t set them up as an authenticator. Can you please help me with this??

Stick ok, Versand Katatrophe

Ich habe heute meine Sendung erhalten. Zu meinem Entsetzen musste ich feststellen, dass meine private Mobilfunknummer vollständig und für jeden sichtbar direkt auf das Versandetikett gedruckt wurde.
Auf Ihrer Website geben Sie an, dass die Telefonnummer lediglich für eventuelle Rückfragen beim Versand benötigt wird. Eine derart öffentliche Platzierung auf der Außenseite des Pakets öffnet Tür und Tor für SMS-Phishing
Da meine Mobilfunknummer als Sicherheitsanker für die 2FA Accounts genutzt wird, ist sie durch die öffentliche Zurschaustellung auf dem Transportweg kompromittiert. Ich bin jetzt aus Sicherheitsgründen gezwungen, meine Rufnummer bei meinem Mobilfunkanbieter kostenpflichtig zu wechseln. Und sowas von einem Unternehmen das für Sicherheit wirbt...

Best of the best

Leaders in a field of many but only one stands out ! Good job!

为什么不能管理存在里面的项目

比如 fido 存入的passkey 。反正 都是只能看

Disappointing Experience

I expected this app to be much easier to use, but it was disappointing. The setup process is confusing, and the interface isn't very user-friendly. It took too much time to get things working, and the overall experience wasn't smooth. I hope future updates improve usability and make the app more reliable.

No reply, no service!?

There’s no way to contact you directly, nor any response to messages left in the online form. How is that compatible with a service that manages access to important accounts!

App is still broken.

Good luck trying to reset FIDO application, just get an Unspecified Error. Every time.

Falta uma coisa

O aplicativo resolve o que se propõe a fazer, entretanto entendo que seria de extremo valor para o usuário final que além do 2FA TOTP houvesse um gestor de senhas integrado. Eu mesmo seria um propagador do uso massivo das chaves de segurança físicas yubikey se houvesse essa funcionalidade. As chaves físicas, por si só, não fariam um usuário comum comprá-las, pois na verdade só os serviços de grandes companhias aderiram elas como passkeys ou 2FA. Mas um gerenciador de senhas (que é um tipo de serviço bem difundido) com 2FA com a segurança de uma yubikey para acessar o cofre, para mim, seria revolucionário. Falta só isso para ser nota 5.

DarkIcon fehlt

Leider immer noch kein DarkIcon. Den Modus gibts jetzt seit knapp einem Jahr, wird langsam mal überfällig

Português

Falta a tradução para português

No funciona

Sólo me funciona con las NFC. Una lástima para un producto tan caro.

Works fine, could use polish

Please update this app to reflect automatic dark icons in iOS 26. As it stands, this app sticks out like a sore thumb for its insistence on an inflexible branded app icon.

useless on iPad 10th generation

I plug in my YubiKey C Bio and it only flashes 3 times then quits. I can’t even access the configuration of the key. Y is this? My iPad is now my only device

yubico auth is not recognizing my ipad

plugged in my yubi key to the ipad port and saw that yubico auth still shows “Insert your YubiKey”however it does work on my pc

NFC not working

I’m not able to detect key and setup in my iphone. Earlier I ordered 5C version it wasn’t detected then ordered NFC one and wasted my time and efforts. Fix the app instead of wasting money on website UI design.

Dark Mode Icon

Please, make a dark mode icon compatible with iOS26 dark theme!
