Security Key - Black - Two-Factor authentication (2FA) Security Key, Connect via USB or NFC, FIDO U2F/FIDO2 Certified (USB-A NFC)

Yubico are my go to brand for security keys. Very secure easy to set up and great value for money considering the price of mine and protection they give.

Very effective and does the job with no hassle

A very helpful little bit of kit to add to your wider privacy set up. I cannot, however, for the life of me get UFC to work via iphone. Supposedly, plugging it in to a computer/other powered device for at least 3 seconds should fix that. It works well on my USB-A compatible devices though, that’s the main thing I wanted. A natty idea to help prevent stolen account details via phishing scams on accounts that you apply it to. There’s a range of services these little things are compatible with. Though, if you have something specific in mind, you’ll have to double check with whatever service you want to use the hardware key with. Edit: I managed to get NFC to work. How you position the yubikey against your particular model of phone matters. Their website has more information on this in their support section.

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.

Nothing fancy, but it does a good job and works well with our PCs and our mobile phones (using NFC technology).

I bought the USB-A with NFC, since my PC has no USB-C ports (MSI X470), allowing me to use it across my phone and PC. The only issues I've had have been with Windows trying to use "Hello" (despite having no compatible peripherals), but that's Microsoft's fault, and being a standard FIDO key allows it to work perfectly on Linux. I'd recommend putting it on a keyring with a clip, since it's not a good idea to have lots of weight dangling from a USB port, but I keep losing it when not on a keyring.

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.
