How does changing passwords fix the problem over the hacked security questions that may have been used on other services. Eg First pets name etc.  If hackers have that info, they potentially could get access to other services with other providers, what is being done about that?



No one should use correct information for those questions. I treat them like passwords and enter unique answers for each site if I cannot make up my own questions. Save it all in Lastpass and no need to ever worry. :)
