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

Works as advertised. Easy to install.

it is a nice handy security key. I was able to easily set it up.There is a green indicator light that blinks when action is needed, in this case a touch on the 'y' logo works.I've been able to connect it with my phone via the USB charging port and it works.It is a functional little key that I can carry with my keys.It seems to be durable, so far at least.

While this key is cheaper, its functionality is slightly limited in comparison to some other Yubikey models. I didn't realize this at the time, and got a bit lost in all the product reviews and comparisons. This one serves as a second factor authentication method for many popular websites, but does not support the Yubikey Authenticator app. I'm keeping it anyways, because it serves my main objective, but I can't help but be a bit disappointed that for a little more money I could have added a bunch more features. It's also a bit confusing to get started, but the Yubico tech support responded to my question within a couple hours, which was nice.

I bought this so I could add a security key to my accounts that was supported by my new iPad. I did not do my research well enough as I thought this was the same as my Yubikey 5 I've purchased in the past but with a different connector on it. It does not support the 2 factor authentication slots like my previous keys as this is strictly a FIDO security key. After I received them and realized they were missing the functionality I was expecting, I saw that they were advertised exactly as they came, but I just didn't realize at the time. I should have realized because they were much cheaper than ones I've bought in the past. As a FIDO key, these work fine and I have had no issues with them.

Easy to use and secure

This FIDO security key that's able to be used via NFC or USB C is pretty good but was initially hard to set up (you might have to do it off of desktop).Works fine, is made of plastic, pretty small, and will probably last for a while.

After reading that even with 2-factor authentication [2FA] or one-time password [OTP] cyberthieves can gain access to your online accounts through a sim swap I thought I should get a physical security key. This little device stores information and generates one-time numbers for you to log in to a site, but you have to register it once, for each online account you use. A bit of online search suggested Yubikey 5 as an affordable, dependable and easy-to-use physical key. One was advised to buy two, with one as a back-up: if you lose one, you still have a second one.After the two keys arrived I tried it out. The first challenge: the key needs a USB-C port for connection to a laptop. My laptop has two USB-C ports. One is used for power, the other for the mouse receiver. So I bought a USB-C splitter. I should have checked online – I found out you can’t plug the power USB-C connection into a splitter [it does not charge], and the Yubikey is not recognized when sharing a spitter with the mouse receiver.However the biggest drawback is that mainstream financial institutions are not set up for use of a security key. One bank uses a security token [which is not the same as a security key], another only goes for two-factor authentication. Basically the only two common online sites for me were Microsoft and Google. Even that was not simple. When you plug the Yubikey into a working USB-C port, you apparently need to set up a pin but if that already exists or if you need to set up a new one is unclear. There is no ‘easy set-up’ or’ set-up for dummies’-something really simple that guides you through a Yubikey set-up even for Microsoft. The Yubikey instructions consist of a 130 page PDF filled with jargon. You apparently have to go into your computer’s Microsoft account settings to include a security key. Also did you know that for Google your pin [4 numbers] is not the same as your Google password? I locked myself out from including the Yubikey on the Google account because I could not understand what the pin was Google was asking for.In addition, I don’t think a security key solves the problem of a sim swap for the average person. Although you could use it to log into Gmail or Microsoft [provided you got that going] on your cell phone using near-field communication [NFC], people don’t usually log in to those accounts separately anyway on a cell phone. Once the phone is off the lock screen, most apps are ready to go without additional authentication. Maybe I am less smart than the average person but in the end, my two Yubikeys and the USB-C splitter will end up on the electronics trash pile.

It works with windows, no complaints.
