Thetis FIDO U2F Security Key with Bluetooth ENBL, Two-Factor Authentication [Extra Protection] Compatible with Windows/Linux/MacOS, Gmail, Facebook, Dropbox, SaleForce, GitHub and More

I've gotten the bluetooth working on laptops/desktops. But, on mobile support seems lackluster. On top of that, relatively newer phones (like my Pixel 3) can already act as their own security keys making this product not the most useful. With laptops/desktops the bluetooth does work; however, my experience is that it takes 5-10 seconds to connect and authenticate. In the end, I just plug it in because it's actually faster. If you misclick the button when trying to plugin, you have to wait a good 10 seconds for it to stop before you can use the usb authentication, can be annoying. Very cool product, bluetooth takes too long to connect, probably better off getting the Thetis key without the bluetooth (also a great product).EDIT 12/16/19: I've changed my review to 5 stars. Bluetooth slowness seems more a result of crappy Bluetooth on my laptop and recently I've been using it more on my phone and it works really well with my phone. Connects much faster and is perfect for phone.UPDATE 3/13/22: Almost 3 years later, the key has been permenately on my keychain and it still works. I still hardly use the bluetooth function though. The bluetooth in general is slow and impractical when you can just plug it in. I mostly use this key for my Google login, so on Android - if an app DOES require me to log into Google, it's because it's using the built-in browser, which doesn't support logging into Google with your key. However, most of the time apps are able to use your phone's connected Google account, to automatically log in. So, I really only use it on my laptop, and plug it in each time.

I wanted to get off of using text messaging/e-mail for my second factor authentication and was looking around at all of the USB keys. I was a little nervous with the fact that it was half to a third of the price of competing products, but I really liked the fact that it offered both Bluetooth and USB options. The metal outer case seems solid, and the design of it makes me comfortable that it will not slip out from the pivot points. When it is folded in to protect the USB port there are detents that hold it in place, though it is easy enough to rotate back out.The plastic on the USB port is on the more flexible side, so I don't feel too worried about it cracking or becoming permanently like some of the metal ports on flash drives. Pairing with both my phone and Chrome on my computer was a quick and painless process and I was able to get it associated to several accounts without any troubles. Will definitely be looking at them if I ever need another key, and will be recommending them to friends as well.

Ah, the classic case of buyer's remorse!I knew I needed two security keys so that I can use them with my iphone and Google accounts.... I knew that they needed to be FIDO and one could be NFC and one could be Bluetooth. I purchased a 5 Series from Yubico and I had really considered one with a lightning connection, but after surveying all the offers, I talked myself into finding a lower priced key as a backup to the Yubikey.I thought I was getting a great deal.... I considered Bluetooth to be a value adding connection option, but it turns out that it was a bit of a dud.Bluetooth is not as secure as NFC. If you are like me and you need a more secure login... as in ... you are making this purchase because of the security it will provide... I didn't do my due diligence... the bluetooth feature actually creates a brand new vulnerability for me. Unfortunately for me, I didn't realize this in time.... I had already paired and had been using the key before I knew the situation I was creating. Now I can't even have the key around me or rather around my electronics.Situation could have been avoided.Now I'm stuck with a purchase that is completely useless. Lesson learned - always do your research before making a purchase!

Had a few issues / annoyances setting up, but nothing major. Overall a good purchase and worth the money.Edit:Never could get the Bluetooth functionality to work. On my Android phone OR Windows. I put it aside and didn't contact the company for support with it till after the warranty period, so I'm just out of luck. Works fine as USB, but I'd be wary of it if you need Bluetooth. Check it immediately, and if there's even a hint of a problem, contact the manufacturer for a possible return.

Works as advertised. Pairing was fast but the passcode is printed on the back, I might write it down somewhere and rub it off for security.It's fairly robust and solid however the black finish seems to be prone to scratching and rubbing off (see pictures), deducted 1 star for this. The images are after about 1 month of being kept in my pocket with no keys attached to the keychain (just a wireless fob). If you attached this to a keychain with keys on it it'll look rough fast.All-in-all it works great and does what I need it to do, I'm not too concerned with the scratching, but it would be nice if it was coated with a tougher finish. It does feel like it should hold up for a long time though.

Setting it up on MacOS and Windows was no problem and worked great. Trying to get it to hook up with Bluetooth to my Android and iOS devices took a bit more work, though the connection process was easy.As with any USB device, the computer takes almost one second to detect and understand what is plugged-in to the USB port, which is quick enough. Tapping the little button works almost instantly, and then the device can be unplugged. On iOS, sometimes the connection is a bit strange and doesn't work as desired, but it does work occasionally with some websites/apps.Carrying the device in my pocket (so I don't get locked out of accounts) is fine, and I hardly know it's in my pocket.After hours of research, I chose this one over all others, and I have no regrets.

Este un dispositivo para asegurar cuentas en linea por medio de un dispositivo fisico que reemplaza autentificacion por APP o SMS.Thetis , Yubikey y Google Titan tiene diferentes rangos de sitios y cuentas que pueden proteger. Thetis si se puede utilizar para entrar de cuentas de Microsoft a pesar de lo que dicen los comentarios en ingles PERO no con Windows Hello, se tiene que abilitar la opcion de entrada por cuenta de Micorsoft lo que tiene sus propios problemas y no lo recoemndaria para este proposito, hay USBs con huella dactilar para este proposito en especifico.En mi caso sirve para lo que lo necesito, recomiendo revisen la pagina official del fabricante para ver que sitios y cuentas se pueden proteger. Yubikey tiene un mejor rango pero el precio es notablemente mas alto en Mexico.A este punto, estos dispositivos no tienen una adopcion massiva pero siguen siendo un paso adelante a auntetificacion por SMS (lean SMS swap) y es menos molesto que usar una app de autentificacion.

the security key is very well made, doesn't feel cheap when your holding it, unfortunately it does not work with Windows hello/Azure Authentication. however i am using it for everything else (google etc)
