Review on 🔑 FIDO U2F Security Key: Thetis Aluminum Folding Design - A Universal USB Two Factor Authentication Solution for Enhanced Protection on Windows/Linux/Mac OS, Gmail, Facebook, Dropbox, SalesForce, GitHub. by Adam Jackson

Not much to say about the security key. Either it works. or not (and therefore defective). There are no additional features to compare or specs to evaluate. However, the key works and costs less than other offers. Tested with Google and Twitter. I originally bought it for added security when logging into Windows. However, it seems I didn't do my research thoroughly enough, and at the time of writing this review, Windows 10 doesn't support login keys (although there is an option to do so in the settings). This is a Microsoft bug, not this key. However, this is something to keep in mind if you are looking for it. Website login integration (where supported) is very simple, although additional steps may be required. Again, this is a reflection of those specific locations, not a key. The key itself is made of hard plastic and some kind of metal case. When opening, the case clicks gently (but firmly) into place and feels good. The button has a nice tactile click and it fits VERY COMFORTABLY with the USB port. Too tight for my liking but I guess that's the price to pay for durability. Doesn't fit on my keychain. Also, when closed, the case doesn't seem to snap firmly into the closed position like it does when open. But other than that it works, and that's about all you can really expect from a product like this.
