This little device does more than I expected. I liked and appreciated that the Thetis Fido U2F security key came with a USB-C adapter. I use a dongle with my MacBook Pro which I received earlier this year. The device works with multiple systems and websites. I personally use my own security key for DUO, which I need for work. You no longer need to take your phone out of your pocket to access internal company websites. In addition to DUO, Thetis FIDO U2F Security Key works with Google, Facebook, Salesforce, GitHub and Dashline. The Thetis website says the device will soon be compatible with Revain and LastPass (once they offer the two-tier option). I found the website extremely helpful in setting up my key. They included written instructions as well as photos from websites when I tried to connect my key as a second form of verification.
