11-year-old Mira Modi has a business you'd think wouldn't be possible, but is. She created a system for generating secure yet easy to remember passwords and has started to sell them for $2 each. Her business is called DiceWARE.

“You roll a die 5 times and write down each number. Then you look up the resulting five-digit number in the Diceware dictionary, which contains a numbered list of short words.”

The result is a string of 5 words in non-sensical order. It's tough to crack and basically people are paying her for them.

Mira generates a password and mails it to a customer on a handwritten piece of paper. She tells people to capitalize random letters and add symbols after they receive it so it cannot be stolen.

Mira makes $12 per hour if she worked on passwords full time.
