In Meta because of bold part, what do you think?
Are you suggesting it be implemented or not, you haven't first giving your own opinion on the matter, you just quoted the original OP. Having said that, this isn't something that's necessary, and it would also be too complicated for some, the proper way to sign into any platform, even our crypto wallets is through our passwords/pin, thus i don't see how this is going to change anything or make the forum better. Safe to say this forum would be unwelcoming to users who do not have any Bitcoin wallet if we have got something like this in place, so no.
I think OP want the members to see it clear and possibly discuss over it here as this board is very important in respect to the development of the bitcointalk platform. Maybe this Idea could be feasible if it is properly debated on and members being convinced as to why they would need it to sign in their various accounts from different location if the need arises.
My take on this, most of private and personal hacks are possibly from compromised web browser which were not detected early enough. Do you not think it would not be different from others if bitcoin follow such steps? It would be obvious that it could result to massive compromise of data and funds as the case maybe.
