sry guys but you are missing the point here. I know there is a free smartphone app.
But this topic is clearly for the separate physical Security key device.
As well as to the point of to every1 having a smart phone. Yes it is rare but that is exactly the reason why such a device is sold. For a company to advertise a device as very secure and great to handle account security it should also be available as advertised.
TLTR: discussion about smart phone app in the appropriate topic please and stick to this thread's topic in here
Greetings
