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

Small, no frills packing. Firmware is upto date and the Key is genuine. (you can check it from yubico's website) At first use, you need to setup a pin using the yubico software. You can disable the NFC option. In the case of NFC auth, you may need to hold the security key for a few more seconds for proper authentication. The key can also store 2FA codes like the ones seen in google or microsoft authenticator and with version 5.7.4, this can store upto 100 passkeys. Security keys only supports FIDO2/webauth and U2F. Security key will function similar to authenticator apps, Meaning you need to enter the account password, insert the key, enter the Security key pin, touch the center gold plated area to complete authentication. (if the app remembers you or the device is trusted, then only the key is required for authentication) If you want quick, easy authentications(instead of the above process), go for YubiKey 5 NFC FIPS as it supports addition security features such as PIV, OpenPGP, OATH-TOTP etc but it will cost more for that same reason. Bought this for under 2900 Rs so the price is justified.

I checked with my laptop and my iPhone working well. and also my IPHONE 16pro supports NFC when I am activating USB security just I am placing on the USB key immediately, recognising. it activates when we touch the yellow coloured circle line with our finger, then only it will activate either using in type C port or NFC.

Genuine product

Best buy for computer security

It is a perfect product

The yubikey is not working only. waste of money . Please don't buy .

Works as advertised, some programs like Firefox did not support it when I purchased it, but it does now. On any other device and program works flawlessly. NFC was a little difficult as I needed to turn on the setting in my phone, but after that it was no problem

This product is great if you are looking for two factor authentication along with your password sign into any website that does support two factor authentication, I've been using it for a little over a month and it has been great.
