HELP!!!

I am posting this thread in order to find some answers.

2. I managed to get my hands on an abandoned premium Minecraft account from ana blog. It worked fine one day but the day after the password was changed. How is it possible to change the password of a migrated account? I also tried to go on the minecraft website the first day but it asked me a question. If there is a way to pass the question please reply.
