Security Key C NFC - Basic Compatibility - Multi-Factor authentication (MFA) Security Key and passkey, Connect via USB-C or NFC, FIDO 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

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

Seller didn’t specify the firmware version of the key in the description. Yubico released 5.7 version is may month and in Jul this seller is still selling 5.4.3 firmware version keys. These are security keys whose firmware cannot be upgraded. You will have to live with the firmware you got and not disclosing it upfront felt like cheating. There is huge improvement especially no of fido2 web authn stored on device. 5.4.3 firmware keys can store only 25 fido2 passkeys where as the 5.7 firmware keys can store 100 fido2 passkeys. Thats huge change and sellers must clearly mention these details.

It is a perfect product

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.

NFC, touch, USB-C. All good. You can also use iPhone’s NFC to authenticate with this security key. Expensive though; double the price of USA.

I am quite new to using security keys like Yubikey and after seeing a friends account get hacked causing them lots of grief I thought about my own security. Setting these up is quite straight forward you download the Yubico authenticator app and set a pin. The pin is what you will use when you log into websites with the key that support these and get that pin wrong upto 8 times the Yubico will factory reset itself. The reason for this is if somebody steals your key it gives you that added protection. You can either use a yubico security key as the final step in 2factor authentication on a supported website or a passkey on a supported website. Support for these is a bit patchy and different websites might implement them a little differently. It's worth watching some tutorials on Youtube if you're a beginner and interested in these. There's other YubiKeys that offer more features so best do your research and choose the one that meets your individual needs. The Security key here is the most basic but does what I personally want. Pros - Stronger protection than say SMS codes for 2FA authentication. Only you have the physical key! - Setting them up as Passkeys offers strong protection against your login credentials being stolen and is convenient. Microsoft is one place that's starting to move away from Passwords and offer passwordless logins. It sounds less secure but it really isn't. Phishing is one of the leading ways hackers gain your credentials. Cons - You ideally need at least two in case you lose one, so keep one or more for a spares. - You have to weigh up your own security needs but it might be worth having another way into your account if you do lose or damage them. Websites typically offer multiple 2FA methods to confirm it's you. Only you can decide on your needs and your security will only then be as strong as the lowest method attached to that given account - A little learning curve but not difficult as such, like I say watch some tutorials if you're new
