Very versatile and easy to set up. A great idea for a little bit of extra security with online accounts.Sometimes the NFC functionality can be patchy on iPhone but a few attempts normally does the trick.A little bit expensive for what it is, but the Security Key NFC version is cheaper due to lack of TOTP / Authenticator codes and other methods.

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.

I love that it is compatible with Bitwarden Premium, 2FA authentication, works with NFC on my my Android and iOS phones. Compatible with my PC with a USB-C adapter. Once setup, forget remembering passwords. At this low price, buy two. Store one off-site, in case you lose the security key, you still have access, if youvecregistered both keys with Yubico.

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.

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.

Setting this key up on my Linux machine was a lot easier than I thought! I was surprised that it only took two package (YubiKey manager and libfido) installs for it to work with my browser. It's touch-enabled, but is non-biometric which works for me since I usually have issues using fingerprint readers. Once set up, I would only have to plug it in, enter my PIN and touch to activate to authenticate to my services.However, I just don't like the NFC feature on this product. After downloading the Yubico Authenticator app, tapping this key to my phone then inputting my PIN, my saved credentials would show up indefinitely until I close the app. No, I can't just hit 'Home' and be done with it; I have to hit the 'Navigation Bar' then swipe up to stop the background process.I also noticed that not all sites would ask for my PIN once I plug in or tap my key, so what's stopping someone from waving an NFC reader to anyone passing by and collecting information? This seems like an unnecessary risk to take. Not too long ago, Yubico released a security advisory, YSA-2024-03, stating that keys with firmware versions prior to 5.7.0 are susceptible to credential recovery. Sure, this requires the attacker to have physical access, but what if someone discovers a way to pull this off wirelessly?I would have to go for the more expensive option to get one without NFC. I'm still keeping this, but only as a backup.

J'ai était très surpris qu'un petit truc comme ça, pouvez faire autant. Je l'ai acheté pour mes comptes mails et autres sites qui fonctionne avec se type de clé USB et très facile à mettre en place.Enfaite ce type de clé ça rajoute un raccourci car une fois sur le site avec un compte soit ont passe par la clé si elle et sous la main ou de passer part l'application traditionnelle comme (Google authenticator) où part SMS. Du coup je pense que ce type de clé USB et tout simplement un gadget .

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.

Simple to set up and use-just input in my username and password at the site I was accessing and then was instructed to insert the key and fingerprint and it was set up. Used a newer Macbook Air and no problems. Don't understand complaints about difficult to use-my experience has been just the opposite. Only wish the Key came with a Cap to keep out dust/dirt but this is a minor nitpick. Would buy again.
