Internet E-mail Problem

Hi Friends,

There is somethign weird with this internet email account. My password is not working from repeated tries, Although there is recovery password, but I dont remember secret question/answer or email id for the backup.

Still I found my way to get back. My concern is how can one hack gmail account. I never clicked any spam or did nothing with this. This worked fine yesterday.but today what happened . I am surprised.

Just like to know any body faced this issue before.
