Key-ID FIDO U2F security key

U2F support works well on dropbox and several nextcloud-hosts. It also works well with Google.When it works well and the host supports it well, it is a real blessing.On the Chromebook it works well. On Chrome and Firefox in Linux you have to make sure things are installed activated and you must accept that some sites will occasionally not recognize it immediately (have to repeat/reload the page it a couple of times for the light to start flashing).Handy and a secure feeling. I particulalry like nextcloud's support of u2f. Separate from otp so you do not need to give your phone-number etc.. It can also allow you to use nextcloud to login to other sites (and rely on nextcloud's u2f) nice.

I bought this Key-ID security key as a more compact alternative to my YubiKey, and it’s turned out to be great value for money.The small form factor is a real advantage — it’s low-profile enough to leave plugged into a USB port without worrying about it getting knocked or needing to remove it constantly.It supports FIDO2 and works well with Google and Facebook logins. Just a tip for anyone setting it up: make sure you set a PIN on the key before registering it with services like Google. I initially added it without a PIN and found it only worked as a second-factor device (i.e. requiring a password first). After setting a PIN and re-registering it, it now works perfectly for passwordless sign-in, just like my YubiKey.If you’re looking for an affordable and convenient FIDO2 key that supports proper passwordless login, this is a solid choice.

Don’t get this security key it can locks you out of your google account

Not much to say; it's a FIDO key and it does what it says on the tin. But... it's the best value key you're likely to find at this price. Mine lives in the back of my Mac Mini and isn't exposed to rough handling etc, but for my MacBook Pro it wouldn't be anywhere near tough enough so I had to get a Yubi for that at almost 10x the price.To summarise; 100% reliable, but doesn't look like it would take much to break it so not an ideal choice for using on-the-go.

Works with gmail for business fantastically, Facebook and all the other 2fa which use this technology. And if you lose it, just delete of your account and it's useless. Perfect for a security, at home and at work, with the added bonus the other half can't read my emails

This was really easy to use with various websites (Github, Facebook, Google) in my Chrome browser. I just plugged it into my Mac and pressed the little button when instructed by each website. I think I'll get another!

Works well however beware - the LED is obnoxiously bright!

Works fine, as advertised, with Google and Facebook, but little else. Says it works for Dropbox, but I don't use that. Says it's compatible with OS-X but all that means is it works with the aforementioned on OS-X not the OS itself. Disappointed. At least my Google and Facebook are more secure now.
