Yubico Security Key - Two Factor Authentication USB Security Key, Fits USB-A Ports - Protect Your Online Accounts with More Than a Password, FIDO Certified USB Password Key

- Works flawlessly for in web browser access to GMAIL and GITHUB on Ubuntu and Windows XP.- Don't forget to configure text message second factor in GMAIL as alternative method in case you need access from your phone as well. Or go with NFC model.- Buy two and keep second key at home as recovery option in case you lost first one!- BTW both Chrome and Firefox have build-in password managers that use this key as second factor. Very happy!I wish banks begin adoption of this authentication instead of silly passwords for online access.

There are a lot of 2FA keys out there. Yubikey is one of them. Possibly the most popular...not necessarily the best. Yubikey does what most of them do. The #1 thing you need to know, and this is true for all keys, is you actually need TWO keys to make this work...a primary and a backup. If you set up any key for authentication, then lose or damage in, you are well and goodly screwed. So, if you're investing in a 2FA key, might as well know you're gonna need to buy two. One more thing...2FA keys, all of them, are a PITA to set up. I'm not hatin', I'm just sayin'.

I've been having some issues with online harassment recently, and the attacks in question came very close to compromising my accounts. The simple step of securing my email accounts, online banking, and social media accounts with this so continent. Not having to request a text message and using local 2-step authentication makes security much easier. The ability to use this device across platforms is what makes it so convenient. I can use this on my desktop, the workstations in school, my Chromebook, or my phone.

This key does work with U2F sites (I have yet to find a FIDO2 site). For example this worked as advertised with Facebook.Note this does require you have a compatible browser; on Windows 10 this means chrome.Edge does not work with this key as of build 17704 or earlier (it seems the FIDO support in edge is lacking)This key does not work with Windows 10 Hello, the support does not seem to be in windows for FIDO2 keys at this time (build 17704)Windows 10 Hello will work with yubikeys (they use the CCID format); note this key is NOT a yubikey (see its not called that in the description - yup well done marketing at confusing everyone! - yubikeys support things like PIV and CAK, this does not, and is why it is cheaper).If you need windows 10 hello now, buy the yubikey 4 (it only supports FIDO UDF - but it will work).Will update if and when FIDO2 support is in Windows 10.

I bought this key to use with my crypto currency account for added security. Once I finally got it set up it works great. When I attempt a transaction I receive a promote to insert the key in my UBS port, the the tab lights up for me to place my finger for authentication. The only issue I have was setting it up. The instructions provide a website address from there you select you model then a "protocol" from a drop down list of technical terms for which I have not idea what any of them mean. Then if you have figured that out you move on to another confusing list of "category". I decided to abandon the set up and start Googling and YouTubing for a common sense walk though. It was then that I discovered that I did not need to set up anything, the key works directly out of the box with my crypto currency wallet. A simple statement at the setup page that informs users that you may not need to do anything to active the product and to check security protocols of the account you want to use it with first for detailed instructions. This is a good product and I would definitely recommend it but the confusion around setting it up degrades from a 5 to a 4 star product for me.

This key provides great two factor authentication. It can't be phished (used by criminals) because the response it sends to the server is tied to the website you're currently on. Works without any drivers or setup on Windows and Linux. Supported out of the box on Chrome and only requires minimal setup on Firefox (go to about:config in your address bar, acknowledge the warning, search for 'security.webauth.u2f' and double click the text that says 'false').I would recommend you purchase two of these in the event you lose one in order not to lose access to your accounts. You can register multiple keys at almost all websites and keep the backup key in a safe or other secure place.

Simple to use. I followed the instructions on how to change to two factor authentication on GMAIL and I was impressed how this worked on my MAC but, I did not realise that it also locked-out my GMAIl account on my iPhone and iPad, which keeps demanding the password and then refusing access. I need the mobility of email on my other devices so the key has made that more of a challenge.There may be a solution which I have yet to find. If so, i will update this.

Hardly a day goes by without news of another data breach. The bad guys have password-cracking down to a science. Having a code texted to your phone sounds good, but the same bad guys have figured out the "SIM swap," in which they take over your phone.The YubiKey solves that problem, and the YubiKey 5 with NFC supports all the needed 2FA protocols, and works with your phone if you have NFC. I've carried an older model on my key ring for nearly 10 years with no problems. However, if you tend to lose keys, buy two, register them both, and keep one in a safe place at home!
