Should I have two Apple Devices for security?
While I have several Apple devices, my wife only has her phone. I know if I were to lose/damage/destroy my phone, having a back-up device where I could respond to push notifications would probably help get up and running again. I have been considering getting an iPad for my wife so that we would have this backup device if she were to smash her screen or something. I always keep our security settings up to date, print out the backup codes, I'm the recovery email on her account. Is there any more benefit to be gained by having an extra device already signed in to her Apple ID?
Assuming you recommend having a backup device, would an old phone serve the same purpose? Can you disable the sim and just log into the phone and keep it online as a backup? What is the best practice?
