I travel alot and thus play from different locations, sometimes as many as 12 in a month. There are times when I get the "Your account has been locked due to suspicious activity" and I have thru go process of waiting on the email exchange of verifying my info and changing passwords. This is a pain in the ass when trying to box on the road.
Other times it just asks for my authenticator code and I'm on my way.

My issue here is that I DO use the mobile authenticator, yet even after entering the proper code I still have to do the email thing sometimes.

I think I'll like this new system when playing from my home PC
