In the old old days, in my youth, I was fascinated by hacking mailboxes for interest, presenting a list of five secret questions that you should not write to restore a password.
1) What color is my hair? (Yes yes! It is! Blonde for the first time.
What color are my eyes? (Cary came from the second time)
In which city/country/planet do I live? (usually from the first time after viewing the infos in aske)
What is my zodiac sign (their 12, maximum from 12 times)
5) Any info from ZJ, blog and personal page in the innet.

The Five Funny Questions.

With whom did I change my husband? (I hope my husband saw it)
2) What is the name of my little friend?
The girl's surname of my cousin's cousin
4) My weight (it's great if the person forgot the password - went, weighed, fit? almost like a fingerprint - the main thing is not to get fat or lose weight)

And most importantly - remember, there will always be a person smarter than a brutforcer :) fool and firewall and antivirus will not save.
