Cihaz dün elime geçti. Apple ekosisteminde (iki adet mac os bilgisayar + iphone cep telefonu) denedim, gözlemlerim:- Anahtarın fiziksel olarak kalitesi fena değil. Keşke bir şekilde bir fiziki koruması olsaymış.- Yazılım biraz sıkıntılı ama iş görüyor. Yazılım için arama motorundan şunu aratın: ftsafe FT_SK_Manager . Anahtarı kullanmak için bir driver/yazılım kurulumu gerekli değil, anahtar doğrudan çalışıyor. FT_SK_Manager yazılımı PIN kodu ayarlama, anahtar üzerinde kayıtlı olan siteleri görme/silme gibi işlere yarıyor.- FT_SK_Manager uygulamasını çalıştırıp cihazı USB'ye taktığınızda uygulamanın anahtarı görmesi lazım. Burada manager uygulamasında aslında cihazda PIV fonksiyonu olduğunu da görüyorsunuz ancak bu işlev Mac OS'ta çalışmadı. Zaten üretici tarafından resmi olarak bu cihazla PIV fonksiyonu olduğu da belirtilmiyor.- iOS için bir manager yazılımı bulamadım. Keşke olsaydı, NFC'yi test etme şansım olurdu, zira NFC'de sıkıntı yaşadım.- USB üzerinde FIDO ile bir sorun sıkıntı yaşamadım. Giriş hatası gördüğüm durumlar sadece anahtara gerektiğinde ve zamanında dokunmayı unutunca oldu.- NFC'de ciddi sıkıntı var. Apple ID için anahtar tanımlamasını cep telefonu üzerinden sorunsuz olarak NFC ile yaptım. Sonra da aynı apple hesabına bilgisayar (USB) üzerinden anahtarla giriş yapabildim. Ancak denediğim diğer sitelerin hiçbirinde NFC, dolayısıyla cep telefonunun içinden giriş çalışmadı. Denediğim siteler: google, sony, microsoft. Bunlarda anahtarı okutun ekranı geldiğinde ve anahtar telefonun üst kısmına yaklaştırıldığında ve anahtarın üzerine dokunulduğunda hiçbir şey olmuyor. Bu gerçekten can sıkıcı bir durum ve sebebini bilmiyorum. Örnek bir NFC okuyucu uygulama indirip denedim ve uygulama anahtar telefona yaklaştırıldığında bir NFC cihazının mevcut olduğunu görebiliyor.Sonuç olarak cihaz uygun fiyatlı, USB'den sorunsuz iş görüyor ve Feitian da az çok güvenilir bir şirketmiş ancak ben NFC probleminden ötürü bu cihazı (en azından iphone kullanıcılarına) tavsiye etmiyorum. Notum 3.5'tan 4.Bazı tavsiyeler:- Cihazınız çalışmıyorsa işlevi için üzerindeki metal kısma yeri geldiğinde dokunmanız gerekiyor, onu unutmuş olabilirsiniz.- Güvenlik anahtarı 2FA işlevi gördüğü için çoğu sitede varsa o sitede önceden kullanıyor olduğunuz OTP authenticator uygulaması kodu ile giriş seçeneğini kapatmanız gerekmiyor. Dolayısıyla anahtarı denemek için bir tane alabilirsiniz, kaybolursa authenticator ile giriş yapabilirsiniz, memnun kalırsanız ikinciyi alırsınız. Ben yedekleme olsun diye baştan iki tane aldım, gerek yokmuş. Ancak bazı siteler anahtarı yalnız başına kullandırıyor (yani authenticator kodu seçeneği olmadan), ona da dikkat etmek gerekiyor.- Microsoft hesabına anahtarı tanıtırken 'anahtar sadece bu bilgisayarda çalışır' uyarıları verdi. Farklı bilgisayarda henüz test etmedim ama bu tür durumlara dikkat etmek gerekiyor. Dediği gibiyse örneğin evdeki bilgisayarda tanıtılan anahtar işteki bilgisayarda tanınmayacaktır.- Baştan FIDO PIN kodu belirlemeseymişim, PIN'i anahtarı tüm sitelere kaydettirdikten sonra açsaymışım kolaylık olurmuş sanırım.- NFC sorununun etrafından dolaşmanın bir yolu belki 2FA'yı geçici olarak kapatıp, telefondan 2FA'sız olarak giriş yapıp sonra 2FA'yı hemen geri açmak olabilir; ama ben NFC desteklediğini söyleyen bir cihazla neden bunları yapmak zorunda kalayım?

Have been using it for a month now and no issues so far. Will provide a review later after I use it more..

La uso como doble auténticación para facebook y me ha funcionado bien sin problemas en lap windows.

Verwende diesen Fido Key nun seit mehreren Jahren und bin absolut zufrieden.

I've been using this hardware key for around 3 years now, and I feel like it's appropriate for me to review it at this point. I use this as a 2FA device for login into Ubuntu, and any online services that use it, both on Linux (including Android) and Windows. While it took a little bit to set up in Linux (editing udev rules, pam files, and such), there was a great guide online by Yubico that detailed the process, and it works perfectly with the Feitian key as well. I'll also add that the NFC worked perfectly out of the box for my phone, and it even worked through a thick case (an OtterBox). Just make sure you memorize where the NFC chip is in your phone to make it easier for you to use.While I was originally uncertain about the durability of this key, it's lasted me over 3 years now with HEAVY use, and I even bought a second one recently and registered it everywhere to make sure I have a backup. The contacts have corroded slightly over the years, and the plastic has been worn out, but it's somehow survived this long despite being on my keyring with all my other keys scratching it, and while working as a laborer with them always in my pocket.On a second note, I believe that this only used to work in Chrome (Chromium works as well if you still use a 32 bit install or an old OS, but I can't vouch for whether or not it would be able to recognize the device if your computer is that old), but it now also works on Firefox (and TOR by extension, since it uses Firefox).This key does NOT work with Windows Hello, but as far as I can tell, neither do Yubico products or any other hardware keys without Azure AD Premium (though I can't even attest to that working properly), so this is the fault of Microsoft, NOT Feitian. Windows Hello has "hardware key" as an authentication method, but rejects any of the keys I've used, so I don't understand what it wants you to use (I've seen reviews on every Yubico product with the same information). Yes, Yubico has software to change the login to enforce hardware key authentication (which doesn't work with Feitian), but this can easily be bypassed by booting into safe mode, so for the security conscious, I'd simply recommend ditching Windows, or just dealing with a password without 2FA. I believe that the same is true for Rohos, but Rohos works with Feitian (I've confirmed this). The only downside is that Rohos costs $32USD after the 15 day free trial, and with a security flaw that big, I don't believe it to be worth the money. I also have not been able to get it to work with my Microsoft account, but I again suspect that this would be the same for a Yubikey, as the same dialogue popped up when it denied the key. I hope that this changes in the future, but given Microsoft's turnaround time on features and the continuous lack of certain security features, I don't know when or even if that will happen.I've seen some people address security flaws, but Feitian has since fixed them, and been very responsive to feedback given by customers! The original flaw with UF2+CCID mode being exploited is gone now, and they improved their packaging to a tamper-proof plastic and cardboard package.For the price, this is absolutely the 2FA device to get, and unless you care about storing PGP keys, then there's no reason to buy a Yubikey over this device.Another side note, Feitian is the company that makes the Google TITAN series of hardware keys, and they're simple rebrands in white, so I recommend you buy them straight through Feitian instead of Google, simply because of markups and such. If you care enough about the color, then I suppose you can get the Google TITAN keys, but I honestly prefer the black one Feitian sells anyway.I'd also like to add that yes, Feitian is based in China, and these keys are manufactured in China. They still use FIDO2 and other international standards however, so this fact does not matter for security reasons. There is no way for them to see what accounts are used with this device, so even if they DID store and track these devices, they couldn't use them for anything. When you understand how these devices work, it doesn't matter from a security perspective who manufactured them, and given the responsiveness to a previous security threat with this device (which was hardly even a vulnerability), they've proven that they certainly care about security. Another one of their products that had a vulnerability in the Bluetooth pairing method (which I don't personally agree is a secure protocol to use in the first place, but that's beside the point, since I believe they were simply trying to appeal to a wider audience) was immediately addressed, and they replaced the product free of charge for every customer who owned one. Feitian actually has a significant history as a security company that I recommend you to look into if you're still questioning their credibility, but with how they've handled their products, and specifically the type of device this is, it doesn't matter that their products are manufactured in China.TL;DR: As a long time user, I highly recommend this product for it's durability, usability, and compatibility. It achieves the same thing as a Yubikey (except for storing PGP keys, but if you don't know what those are, then it won't matter to you), for half the price. My current key has lasted me over 3 years, and I suspect it will last me far longer still.

Everything works as expected. The only thing that's a bit annoying is the NFC.If you have a thick case around your phone then it might not work every time. This is my first set of security keys so I don't know how they compare to the more expensive models.

I am really satisfied with this product! A very affordable U2F key if you compare it with Yubikey which doesn't offer that much more. Works excellent as a plug & play device for authenticating with Github, Facebook, Google, Bitbucket, Dropbox, Sentry etc.

Guter U2F Stick, nichts Negatives bis auf den Preis. Wobei dieser im Vergleich zum Yubikey auch noch relativ niedrig ist und damit eine Empfehlung wert ist.

als U2F stick läuft dieses ding absolut nice sowohl mit NFC und Android als auch über normales USB mit windows.Anders als viele der aktuell erhältlichen U2F sticks ist er durch NFC und dadurch die Notwendigkeit einer antenne schön groß und somit schwerer zu verlieren.Aber es gibt nur ein potenzielles Problem in der Langlebigkeit.beim testen mit dem Yubico Demo tool ( demo.yubico.com/u2f ) fiel mir auf dass anders als bei allen countern der counter nicht nur um 1 sondern um hunderte steigert. soll vielleicht bei der anonymisierung helfen, jedoch beim steigern um teils hunderte auf einmal mache ich mir schon sorgen dass irgendwann ein maximum erreicht ist. die höchste aktuell 100% sichere zahl ist ja 2 147 483 647. das heißt dass man sicher n paar millionen vorgänge sicher drin hat, jedoch macht es mir auf dauer schon sorgen.Eine sache noch im Bezug auf einige Negativbewertungen dass der STick kompliziert zu nutzen sei. Das stimmt eigentlich nicht wirklich.Für U2F sollte jeder halbwegs aktuelle browser der nicht Safari oder IE/Edge ist funktionieren (der rest basiert ja meist auf Firefox oder chrome/chromium) reichen.man geht auf eine seite die U2F kann, loggt sich ein und geht bei den kontoeinstellungen zum Teil wo es um U2F geht (Meistens "Sicherheitsschlüssel" oder so genannt) klickt auf neuen key hinzufügen und aufm Computer steckt man den key einfach rein und berührt die "taste" und fertig. beim Einloggen wird man gefragt den stick einzustecken und auszulösen.Der Key kann zwar auch noch OTPs generieren aber mit der ausnahme von SEHR wenigen spezialzwecken ist dieses Feature relativ nutzlos, da die Meisten Websites Ihre OTPs nach dem TOTP (Zeit) standard generieren, während der Stick nach HOTP (Zähler) standard arbeitet. Websites nutzen die Zeit lieber da man bei Zeit weniger probleme mit dem auseinanderlaufen der Zähler hat und nicht erst im schlimmstenfall hunderte male testen darf (und echtsprechend hunderte codes zulassen müsste) nur damit man noch reinkommt wenn irgendwer zu viel mit dem key gespielt hat. Der Key wiederum nutzt logischerweise einen Zähler, da dieser keine Batterie hat, daher kann man TOTP ohne weiteres sowieso vergessen.Long Story short, nutzt den Key für U2F und gut ist. HOTP ist aufwändig, selten praktikabel und braucht extra anwendungen zum einrichten, alles nicht nötig.

Nicht so Funktionsreich wie der Yubikey Neo dafür aber wesentlich günstiger.Bedienungsanleitung sehr mager.

Feitan ePass NFC FIDO U2F is an excellent product. It works right out of the box. I primarily only use it on my Google and Facebook accounts, but it is pretty reliable. I tried the NFC feature with my Nexus 6 phone and it works.The only issue I have with it is that you cannot use it with Windows Hello since Feitan does not have a software that would allow for the security key to be used for logging into your Windows computers (a feature which Yubico has).

Ich nutze den FIDO Token zum sichern einiger Online-Accounts wie Google, Github usw.Sowohl mit dem Handy (per NFC) als auch unter Windows, MacOS und Linux am PC habe ich bisher keine Probleme bei der Nutzung gehabt.Der Token ist am Schlüsselbund immer bei mir und hat schon ordentlich leiden müssen, aber bisher hatte das nur kosmetische Auswirkungen.Ich denke gerade für den Preis ist das Produkt wirklich klasse.

Das Gerät mag ganz toll sein. Leider lässt sich das mangels Dokumentation nicht herausfinden. Auf der Verpackung ist ein QR-Code abgebildet, der auf das Handbuch verweist. Man findet unter dem Link ein 2-seitiges pdf Dokument, welches ausschließlich 2 weitere Links enthält: Den zu einem chinesischen Handbuch und den zum englischen. Verfolgt man den englischen Link, so erhält man ein 3-seitiges Handbuch, was neben dem Deckblatt noch die Features auf dem 2. Blatt und schließlich noch das Schlussblatt enthält. Die chinesische Version ist übrigens nicht ausführlicher. Auf deren Seite findet man schließlich noch ein Konfigurationsprogramm -- natürlich ohne Doku.Unterm Strich: Wenn man Langeweile und Lust am Stochern im Nebel hat, ist man hier bestens aufgehoben!
