Thetis Fido BLE U2F Security Key with 2-Factor Authentication & Bluetooth Extra Protection, for Windows/Linux/macOS

Have been using it for 2 factor authentication. Handy for securing your account. So far works as advertised

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.

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.

Been looking into getting a Yubikey some time ago and happened on these new U2F-style keys for cheaper so tried one out. This one registered fine on a Mac and tried it with Facebook with instant success. For setup on an iPhone it's a bit harder since not a ton of supported apps but tried it on a Gmail account I have and initially ran into issues where the Google Smart Lock App wasn't recognizing it via Bluetooth LE at all. After many tries and thinking I had a dud, I read some troubleshooting that included "reboot phone" as an option and low and behold, it worked. So now connecting to that Google account via Safari or initial setup in the Gmail App, it'll prompt to use Smart Lock to validate the U2F key with a keypress (works great), but downside is even unchecking "Remember this device" still saves the login, so seems I only need to do it once then just like the Gmail App, it won't ask for it again unless I go into Google Account Settings|Security and revoke all trusted devices. Speaking of Gmail App, it seems Google tends to want to "save" or "trust" devices probably for convenience, so trying to get it to prompt for U2F key every time doesn't seem to be a great option.So while its usefulness will grow as more apps and websites support it or support it more fully, the U2F key itself worked exactly as it should for both plug-in USB and Bluetooth LE transmission to a phone. Oh, one thing that may be nice would be a still-compact version with both USB-C and USB-A capabilities (or attached adapter) since I have old MBPs and a 12" Retina newer USB-C-only machine.Can't wait for more sites to support this standard!

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!

Bought this to use with refiguring a hand me down iPad to install Good mail. Of course trying to make anything that is NOT an Apple Product work with a Google product is... well futile. I did see an article in Apple mail that finally mentioned I would need an adaptor for to convert Apple to USB-C! You mean they make such a thing? dont know who to point the fickle finger of fate at Google or Apple!???
