I've still got an iPhone 6 and a few others because a lot of cool apps (both productivity and games) I love were dropped by iOS quite a long time ago. My only real disappointment with this is that Apple didn't implement some sort of 'Purchases Only'/'iCloud Lite' functionality for old devices. If your device can't be updated to compatible software, you won't be able to sign back in. To sign back into these devices, update to compatible software and use a security key. > During set up, you're signed out of inactive devices, which are devices associated with your Apple ID that you haven't used or unlocked in more than 90 days. That would be a useful hedge, while not needing to offer unlimited trust to any single person (there could also be a few other safety measures like it taking a week and sending the account owner alerts in the mean time).

Would be neat for example to support m of n restore, where if key/password are lost (somebody dies in an accident for example) then any 4 of 6 (or 3 of 6 or whatever) remaining keys can be used to get access. While I know it's definitely not Apple to add extra complexity, if anything it'd be cool if they leveraged this a bit farther even. Everyone still is protected by their password, but if they lose keys/devices then any other family member could be their live backup (and having the majority of keys constantly under control and in active use is good in terms of immediately noticing if one is lost or breaks and so on). Or if (as I'd assume) keys can be reused between accounts, then a family could each have a key, with all keys registered to all accounts, and then 1 or 2 in a safe spot as backup. A number of keys for regular use, a few put in a safe deposit box or safe or the like. That's a very solid number enabling a lot of decent (if basic) backup practices. Yes, and also that they support up to 6 of them. I'm glad to see that they not only support, but require the use of multiple keys.
