My local git repos from which I have been committing, using git llvm push, starting asking for my password yesterday, when they didn't before. If I manually enter the password, it's rejected. Does this mean my password has been reset? If so, is there some interface for resetting it or do I just email Chris Lattner again (as per the original setup instructions)? For that matter, should I be concerned that my password was reset and not by me?
