Why can't you log into iCloud? unless somethings changed in the past year or something broke between ios 6 and 10, it should work. I'm still signed into my iPad 2 running iOS 6 (granted, iirc the root cert expired a bit ago so you need to update that). the 2fa is also a bit weird, you have to input the code after your password (eg: if your password is password123 and the code is 789 you'd submit password123789)

Ask Apple.

I just tried it again.

"Can't Use Your Apple ID on This Device

Your Apple ID can only be used on devices running iOS 15.0 or later, or macOS 12.0 or later. This iPhone can't be updated to the latest software."

		I think that might be a thing with apples Advanced Data Protection if you have it enabled, which is understandable since the software needs to know how to un-encrypt the data. If you don't have that enabled, then ignore this and assume apple decided to kill a whole lot of devices (particularly their macs, I know a surprising amount of people still on 10.15)
