Let me pose a hypothetical situation to you. Let's say your significant other passed away suddenly (sad, I know, but bear with me), and that person did both of your taxes, paid the bills, and other important tasks. That person was also the administrator to the computer with all those files that you will need... but it is password protected and you don't know what it is. You have tried and failed many times to guess what the password could be; the dog's name, kid's name, your name, etc., but nothing works. What are your options?
The majority of people would either take it to a computer shop to see if they can unlock it, or accept defeat and admit to themselves that all that data would be forever lost. But there is a third option, and it scares me.
