Where in icloud can I find my filevault pass key?

The article that tygb suggest is a great general over view of how FileVault works.

I found the answer to my specific question in a Macword article.

https://www.macworld.com/article/3268809/security/how-to-find-your-filevault-rec overy-key-in-macos.html

When setting up FileVault you are given two options. “Allow icloud to unlock...” or “Create a recovery key...”

For those used to writing down and storing a recovery key, you will NOT be given acces to it if you choose the iCloud option.

"If you choose iCloud, the recovery key isn’t stored loosely in iCloud Drive or as a file, but it’s tied into behind-the-scenes account information that Apple maintains. It’s fully encrypted in such a way that even Apple doesn’t have access to the unencrypted recovery key data, but Apple can deliver the encrypted recovery key to your Mac if you need to reset your password. You never see the recovery key nor have to enter it in this configuration."

Im curious how the "Apple delivering the key to your Mac.." would end up working. Kind of sounds weird. Maybe its an email you can somehow request through iCloud?

I am now also curious if the "Find my Mac" feature will still work if FileValt is enabled. I beleive the way "Find my Mac" works is someone has to plug in and put your (stolen) computer online for it to come up in the GPS locator in your phone. FileValult disables (thiefs) from being able to log in/go online?!?
