iCloud Security Codes

None of this stuff makes sense to normal users and is, frustratingly, never explained in detail anywhere for those of us who want to understand and know more.

Could they not add a “Learn More” option? Where’s the iOS equivalent of the macOS Help button?

In the past, iOS has even prompted my to enter the password for my Mac’s local user account. Again, as a developer, I kinda get and understand what’s happening, but even I’m still slightly confused about exactly what data is protected behind my macOS password vs my iOS PIN vs my iCloud Security Code, etc.
