I have a 'bootstrap' system... I have recovery codes and a backup for critical things encrypted and stored in a public git repo I push to both gitlab and github. If I lose everything, I can use those recovery codes to access the things I need to recover my digital identity.
replyPhone number and email access, if you can regain access to them.
replyIt is definitely a good idea to plan in advance and set up a recovery contact: https://support.apple.com/en-us/102641
But email access is protected by MFA based on your destroyed device. Recovery codes are also stored in the same destroyed building.
replyI said “if” for email, which I at least have recovery codes stored with someone trusted.
replyAnd that link is to recovery contacts, not codes. If you’re willing to trust one person you can get back into your Apple account after a disaster.
You can get back your phone number once you have a photo ID and buy a new phone. Then you should hope that your service providers aren't secure enough to have disabled SMS-based account recovery.
