Yubico - Security Key C NFC - Basic compatibility - Multi-factor authentication (MFA) security key and passkey, connect via USB-C or NFC, FIDO certified

They seem good quality and have been a good solution so far. It works well as both a hardware key and security key protected via a pin and physical presence. Ideally if you want to get rid of other authentication methods you. Need two incase you loose one. It's a shame there isn't a discounted 2 pack.

Bought a couple of these to secure my iCloud account. It was very simple to set up and works perfectly either by plugging in or using NFC. If you don't need all the added features and just want a hardware key to properly secure your iCloud or Google account etc, these are perfect

The setup was a bit complicated and difficult to understand. After setup using it is as easy as picking up a USB. It doesn't have any storage. Use of it allows me to log into my millions of accounts securely. It works with all types of USB, except USB C which requires an adaptor. The durability feels tough, dropping it definitely wouldn't break it.

Great little bit of tech for keeping your accounts safe especially as a backup incase you lose your phone! Used to keep Microsoft and Gmail safe so far. Also connected to my iPhone 13 incase i need to log in from there. You can connect and enable NFC by going into shortcuts and adding new automation where you will find NFC. Very easy to set up.

Does what it claims to do perfectly, but the moment it's only usable on a relatively limited number of sites, so I'm not convinced that it offers significant advantages over using a PIN.

Works OK.

Bought this thinking it was a proper YubiKey with NFC that could store and display 2FA codes (Google, Proton, Microsoft etc.) in the Yubico Authenticator app on my iPhone, exactly like the more expensive YubiKey 5 NFC does. It is NOT. Despite the listing proudly saying “Near-Field Communication (NFC)” and “Multi-factor authentication (MFA) security key”, this black “Security Key NFC” is a FIDO2/U2F-only device. It has zero support for OATH/TOTP (the standard used for time-based 2FA codes). When you tap it on an iPhone or Android phone, the official Yubico Authenticator app either does nothing or throws “no privileges” / “YubiKey does not support OATH”. You cannot add accounts, you cannot see any codes, you cannot use it as a hardware authenticator app replacement. Full stop. Yubico themselves confirm this on their website (only the YubiKey 5 series supports TOTP over NFC), but Amazon’s listing never mentions the limitation. The word “passkey” is buried in the description and most buyers won’t know that means FIDO-only. Result: hundreds of people (check the 1-star reviews and Reddit) buy this £26 key expecting full functionality and end up with a door-stop for anything except FIDO logins. It works fine for passwordless logins on Google, Proton, Microsoft etc. (that part of NFC is good), but if you want a hardware key that replaces Google Authenticator / Authy and lets you tap for codes, this is the wrong product. You need the YubiKey 5 NFC or 5C NFC instead (roughly twice the price for a reason). Extremely misleading advertising from Amazon and poor product differentiation from Yubico. Returning mine. Save yourself the hassle and the return postage – spend the extra £25–30 and get the real YubiKey 5 NFC if you want TOTP support. Hope this review stops someone else wasting their money.

Had to return as was not compatible with windows logins and my password database. It's ok for online normal security but its a bit limited. If your looking for more advanced then yubikey 5 or the biometric keys are the way to go. The security go is ideal for someone who is looking to just lock down a few online accounts but thats the limit. Given how the security key is not as advanced I have scored it accordingly.

Excelente, funcionando conforme o esperado

I’ve just started using the Security Key C NFC and wanted to share my early impressions in case they help other buyers. Functionally, the setup went smoothly and the key has worked reliably for authentication so far. From a usability standpoint, it does what I expected. The packaging is extremely compact. That isn’t necessarily bad, but it felt a bit underwhelming for a product in this price range. I also noticed that the device doesn’t have a visible serial number. For me, having one would make it easier to keep track of multiple keys. The design itself leans toward simplicity. The green LED, in my opinion, has more of an older-style appearance, and the overall look doesn’t feel especially premium to me. This is purely a matter of taste, but I expected a bit more visual refinement considering the cost. When comparing it with my Thetis key, I personally feel that the Thetis model has a more solid and polished exterior. Both work, but the Thetis leaves a stronger impression in terms of build aesthetics. Since it’s only day one, I’ll update my thoughts if anything changes with continued use. So far, the performance is on point, while the design elements come across as more basic than I had hoped.
