Yubico - Security Key NFC - Basic Compatibility - Multi-factor authentication (MFA) Security Key, Connect via USB-A or NFC, FIDO Certified

Why did you pick this product vs others?:I've been working from home the past couple of years, and the company I work for recently started requiring stronger security for logging in and out of systems. I picked the Yubico Security Key (the usb version). Honestly, I'm impressed. Setup was super quick. I plugged it in, followed a few steps on my work accounts, and that was it. No extra software or anything complicated. The best part is knowing my accounts are protected even if someone somehow gets my password. You physically need this key to log in, which gives me peace of mind. Save yourself the hassle and just buy it.

These work perfectly fine. Can be inserted into an iPhone, Mac, PC, iPad and Android phone. NFC works perfectly. Durable, but costly for what it is. The biggest problem I have is that the devices themselves make it very hard to select a physical key for authentication. The mac as an example wants to use its own vault. Its just a pita but it isn't the fault of Yubi.

Works well and it’s easy to use. Needed this for work and it does the job to connect to platforms that require additional security.

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.

Side note - I use the open-source BitWarden password manager, which supports Yubikeys. BitWarden is free on multiple devices like PC, Mac, Linux, and your smartphone - for some of the bells and whistles like supporting a YubiKey you have to upgrade to their $10 a year plan, totally reasonable and you should support this company, they are great and my favorite password manager.Now - on to the Yubikey itself. One of the great selling points is that you cannot log on to services that support Yubikey (e.g. your bank, Facebook, Twitter, etc.) if you do not have physical possession of the Yubikey. If someone happened to obtain your User ID and password somehow, they still wouldn't be able to log in thanks to the Yubikey, so that is peace of mind. Speaking of peace of mind, do yourself a favor and buy 2 because you're going to want to store the backup key somewhere safe and easily accessible in case you ever lose your primary key. It is not technically necessary, but it would be an extra hassle to try and prove to the bank or other service that you are the actual client because you won't be able to log in without the key, so there is no easy password reset that you might be used to. Each company has different procedures if you have to call them if you lost your only Yubikey, for all they know you might be a leet hacker trying to social engineer them, so having the backup key gives peace of mind and you can avoid that problem if you are prone to losing things.In a digital world filled with passwords as long as the Great Wall and security measures more complicated than a Rubik's Cube, finding a solution that balances convenience and protection is a quest worthy of a tech-savvy knight.

Just plug it into a USB port or tap it against your NFC-enabled device, follow the prompts to register it with your accounts, and voila! You're one step closer to digital invincibility.The YubiKey 5 NFC is a game-changer in the world of online security – a trusty sidekick for the modern-day digital hero. So, whether you're a code-slinging developer, a data-wrangling sysadmin, or just someone who wants to keep their online accounts safe and sound, the YubiKey 5 NFC is here to save the day (and your passwords).Final note - regular 2FA (two-factor authentication) of the type that sends you a text message with a ~6-digit code can be compromised by "SIM jacking" i.e. a hacker calls and socially engineers your cell phone plan provider like T-Mobile, AT&T, etc., and convinces them that the hacker is you, and you want to transfer your cell service to a new SIM card because you lost yours. The cell providers don't always do a great job in this situation and have been known to transfer your account to the hacker and their SIM card. I guess you would have to be a high-value target for something like this to happen, but it's good to know that the Yubikey protects you from this type of attack and has your back.
