Bob has lost his hotmail password and he can't get any support to help him recover it. Leo says that it may be that the password was hacked and the account taken over. There's a two factor authentication, where if the password is changed, you have to input a code sent to your cellphone in order change the password. But in this case, it's likely they guessed your secret questions with a brute force attack and hacked your account. Secret Questions are a vulnerability because people actually answer the questions. Leo advises to change the password aNd then enable 2nd factor authentication. And then use a password vault like Last Pass.
