With the banks and everyone else tightening up the authentication, it is also no surprise that people like me is also looking at a 2FA solution that log in to my WHS. I had chosen one of the out-of-band solution using the mobile phone. As I see it, this should be the way moving ahead.
I won't say too much about how it is done yet as I am still looking at the implementation, but it is likely I will roll this out this coming weekend and as such all login to the WHS will be disrupted and no longer valid until you have register you handphone with me. :)
I will share out the experience after I complete this exercise.
