KEYS TO THE KINGDOM: your user id and password that gives you access to something only you should have access to OR all of the things that identify you (and you don’t want others to have because they could steel your identity.)
YOUR KINGDOM: Any one of the many things that would qualify as your kingdom, which is a thing that belongs to you and you don’t want anybody else taking or using, like the money in your bank account, or your retirement plan, or your identity, etc.
If you are asking for somebody’s keys to a kingdom:
I don’t give a flying fig if you are as saintly as Mother Theresa, bless her soul, and have the purest of intentions: NEVER ask for keys to any of a person’s kingdoms. STOP IT. You are doing what people with malicious intent do. Again: STOP IT.
If you are about to give away your keys to one of your kingdom’s:
And the rest of you reading this: if you are into giving away your keys to any of your castles (or give away your bank card number and PIN to anybody):
I have some bad news for you: you are a prime candidate for Darwin Award recipient. Educate yourself, please.
OR, I have some terrific news for you: before you proceed with giving away your keys to your kingdom and/or giving away your bank account number and PIN to anybody, you should get a hold of me so we can first complete an awesome transaction: I have a bridge on the other side of the world to sell you for a steal.
BTW, only ever enter a user id and password for one of your kingdoms into a service that is obviously from the same kingdom, and ideally a device that belongs to you.
ASIDE: Read about website spoofing.
And when somebody steels your identify: they then have the keys to your kingdoms, or create kingdoms in your name leaving you with bills for moats, catapults, and a whole bunch of other stuff you don’t remember buying…
