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

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.

Very effective and does the job with no hassle

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.

Works OK.

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

I can't stress enough how crucial it is to fortify your online security, and the Yubico Security Key NFC has become an indispensable tool in my arsenal. This sleek, compact device offers a robust two-factor authentication (2FA) solution that greatly enhances the protection of my online accounts. Setup was a breeze; within minutes, I had it configured with various platforms, including Google, Facebook, and more. The NFC capability adds a layer of convenience, allowing me to authenticate with a simple tap on my smartphone. Plus, its durable construction ensures it can withstand everyday wear and tear. What truly sets the Yubico Security Key apart is its compatibility with a wide range of services and its support for various authentication protocols, including FIDO U2F and FIDO2. This versatility makes it a one-stop solution for securing multiple accounts across different platforms. In today's digital landscape, where cyber threats are rampant, investing in robust security measures is non-negotiable. The peace of mind offered by the Yubico Security Key NFC is priceless. If you're serious about safeguarding your online presence, look no further—this device is a game-changer! Highly recommended.

With passkeys now becoming the way forward for account authentication, it's great to be able to create a backup for important accounts without relying on a PC or Phone, or handing over to Google etc. to replicate them. They are small and easy to use and also useful to act as an off-site backup in case of emergency loss of everything. The only downside I suppose is you really ought to have at least 2 of these and keep them both up to date. But at least they are not TOO expensive.

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.

Excelente, funcionando conforme o esperado

La verdad es un excelente producto para mejorar la seguridad, se activa conectando la USB a un puerto, pero importante mencionar que la PC no reconoce como un dispositivo USB. Una vez que se activa solo podrá configurarse al momento de activar la seguridad en 2 pasos ya sea por NFC o USB, pero si pasan la llave por algún lector NFC o la conectan, el dispositivo no la reconoce inmediatamente, solo lo hace al momento de configurar el 2FA. Me imagino que por eso algunos usuarios comentan que no les sirvió. Tengo una Yubico 5 y esa si se reconoce como USB aunque no la estes usando para configurar en ese momento.

Works as expected with no flaws at all. Robust yet simple

Clé YubiKey achetée pour sécuriser mes comptes. L'application Yubico Authenticator est très claire et fonctionne parfaitement. La connexion est rapide, sans aucun échec. C'est beaucoup moins contraignant que de gérer des mots de passe complexes ou trop faibles. Aucun problème rencontré sur les sites utilisés : Gmail, Outlook, X, Samsung, etc. Très satisfait du produit

This has been really easy to bring with me, and has secured my accounts. No problems.
