Review on Thetis Two Factory Authentication Protection Compatible by John Invert

I bought a physical security key to secure accounts for obvious reasons. This security dongle also supports Bluetooth, making it more versatile with mobile devices. However, after physically using it in a USB port maybe a dozen times. even if about a dozen times, the physical key that is plugged into the USB port is broken and can no longer be used on a non-Bluetooth computer or device. I tried to insert the key into my computer's USB port and the end of the key broke off completely. I don't feel my accounts are very safe if what I'm protecting them with isn't safe in and of itself! And now I need to do some research to find another physical security key and also access all the accounts I have set up with that key using alternate 2 step authentication methods other than my secure physical key and reset all my security settings. Settings for all my accounts again. It was more trouble than it was worth.
