So I have read through the basics of security that I am supposed to know on security issue.
It is majorly complex to have varying password key for different purposes considering the fact this is not the only thing you do.
But careful, I have been able to understand why we need all those level of keys and the most thrilling part of it for me is that the Master Key is actually more important than the Owner Key...
I kept my Master key in my notepad somewhere on my phone and I will have to duplicate it as well.
Thank you for the knowledge and taking time to explain all this to the newbies like me.
