I was working in a highly secured company that needed to keep highest possible encryption. On a random day I logged into my system and it said password denied. Then it caught my attention that the passwords were changed randomly on any day for maximum security and that it could only be obtained from the boss in that case.
I went to the cabin of my boss and said, "Boss, my old password is out of dare."
He replied, "Yes I know about it. Though your new password is different, it has the same amount of letters as your previous one and also four of the letters are same."
Can you deduce the old password and the new password?
