Thanks for your reply---I resolved it --- it seems the 2-factor authenticator unsynced itself (all my other 2-factor worked fine). I think this may due to I withdrew all at once and act as a protection maybe. --- TheQuin helped me and resolved it. able to reset it and everything went fine.

User ID 14629801 -------- 2-factor authenticator not working anymore--- not able to withdraw 0.1 BTC anymore or disable the authenticator --- I heard once on cointiply that one guy has 16 BTC and use freebitco.in for monthly saving and withdraw monthly without problem --- deposit 0.1 BTC to see if it is true. Will any mode help with it?

I started with 0.005 BTC deposit and withdraw with no question, then tried 0.1 BTC--- If this is a scam, I am happy I still have my 10 BTC not deposit on freebitco.in --- Will keep updated and if indeed I am not able to withdraw anymore and scam, pretty much spread this thread elsewhere. Thanks.
