> I know I’ve transferred google auth across phones in the past - although possibly over iTunes? The new iPhone setup process works differently I guess.
There were a few brief years where an encrypted iTunes backup was a perfect, universally-restorable image of an iOS device. You could back up an iPhone, pop out the SIM card, destroy the original phone, then pop the SIM into a new one, restore the backup, and it would be nearly-impossible to determine that the device was different from a daily UX standpoint. Even MS Exchange email sync would still work.
Then around the time that iCloud K/V store showed up (which may be coincidental), this stopped working. Every app would start up and ask you to log in. Email needs reauthentication. Encrypted iTunes backups aren't terribly useful anymore.
