FIDO2 Security Key, Two Factor Authentication (2FA) NFC Security Key, Connect via NFC for Microsoft, Apple, Google, Facebook, Dropbox, Mifare DESFire, Convenient Card Format, FIDO Certified

I recently bought the FIDO2 Security Key and it's been a great addition to my digital security toolkit. Right off the bat, I loved how I could easily slip it into my wallet, thanks to its card-like form factor. Setting it up was a breeze, and I had it working with my Google and Facebook accounts in no time. The advanced security features give me peace of mind, knowing my accounts are better protected against phishing attacks. However, I did run into some trouble when trying to use it with my Android device—it didn't always work smoothly, but it was flawless with my Microsoft and Apple devices. Overall, the convenience and enhanced security it offers make it a worthy investment, even with minor compatibility hiccups. If you're looking for an easy-to-carry and robust security key, this one won't disappoint.

Provides 2 factor authentication for cell phone/ tablets with NFC, works with laptops with external NFC reader. Hold up card to back of phone and automatically authenticate any sign in. Great idea for increase security, works perfectly every time. No one can access your e-mail / accounts with the card in their possession. Great peace of mind. If you are worried about security, this is a great item. Highly recommend.

I bought this without really knowing much about it, but needing to set up a 2FA on my Nicehash account. I tried to get some sort of support for this and eventually gave up because I couldn't figure out how to use it with Nicehash. It does work with some of the other accounts like Google and Microsoft. It uses NFC communication and is supposed to be compatible with Apple, Android and Windows, and with most browsers. In order to use it with a computer, you will need a card reader, which I had to buy separately since my computer didn't have one. For the phones, you just need to find where the NFC reader is, generally either the top or center, and make sure you align it correctly to get it to read your card. This card looks like a credit card, so it is easy to carry in your wallet, making it extremely easy to carry. So far mine is holding up well despite repeated use and being carried around in my wallet constantly. If you have a card reader or a phone that is NFC capable, and you want to set up 2FA, this might be a good option for you.

EDIT: As of September 2023, Google now requires managed credentials to be stored on the authenticator, which as I noted earlier, this card does not support. This means this card no longer works with Google accounts (it might still work if you had already set up your google account with it in the past, I'm uncertain.)Original review:First, I really like that this is in a card form-factor. That automatically tells you everything you need to know about its physical durability, and it will outlast basically anything else. It's really nice to just have a FIDO2 key in your wallet, and you can simply tap your wallet.However, strictly in terms of FIDO2 features, it pretty much sticks to the basics. Here are the features the card claims to support:versions: FIDO_2_0 U2F_V2extensions: hmac-secretaaguid: 9c835346-796b-4c27-8898-d6032f515cc5options: clientPin:true rk:true up:truemax message size: 629PIN protocols: 1max cred count in list: 16max cred ID length: 48transports: nfcalgorithms: Array([Map({Text("alg"): Integer(-7), Text("type"): Text("public-key")})])force PIN change: falseUnfortunately no FIDO 2.1, which means no credential management. I'm really torn about giving this a three star rating as given it's the only card form factor available, which alone gives it a boon if that's what you need. And if it had full fido 2.1 support, I'd use it as my daily driver.

I wanted to find a key that would work in smartcard readers as I am sometimes in a situation where no USB is available. This card did the trick, specifically for Microsoft (business & personal) accounts and Bitwarden. No software needed, same experience as yubikey, just asked to establish the PIN on first use. The NFC also worked well on my Andriod phone.The one issue that I did encounter was when registering as a security key for my Microsoft Business account. As the card is only FIDO2 Level 1 certified (this might not be the only reason), Microsoft Business accounts default settings do not allow it to be used. I had to toggle the "Enforce attestation" to off. Hopefully this is something that gets worked out in the future and my only reason for not giving a 5 star review. I will try other cards as I find them and update this review if one works with attestation.

So much better to have access to one of these in my wallet and one of these somewhere else to keep my phone safe

Contact every provider for assistance and your left with nothing. Cards wouldn’t activate, cards aren’t able to be used after initial setup. I did the step by step and it didn’t work out. Greatest idea but nothing.
