I couldn't schedule a repair at the genius bar and to go in person I could only find apple stores in malls (which I can't stand), going through all that for them to ask me the same shit in person possibly and deny repair is not worth it.

So I just went to a nearby repair guy who only asked for my phone number to update me on the repair status.

How do you do when you drop your car at a mechanic ?

My car doesn't have access to my emails.

It has your location history though, since you apparently all face presidential level threat in this forum I guess that would be very important. They could also plant microphones and cameras !!

At some point you need to trust your vendor or why are you even buying their products in the first place

Vendor != some repair guy in vendor's shop.

Plot twist, Mr Apple never fixes your phone himself, it's always a guy in a vendor's shop. Same for the components, they're made by guys in vendor's factories. And the software is made by guys in vendor's offices

Samsung phones have a feature for this specific scenario. Maintenance Mode creates a temporary user account, allowing a service technician to test all of the functionality of your device without exposing any user data. Given Apple's stated commitment to privacy and security, I'm surprised that there's no equivalent feature. https://www.samsung.com/uk/support/mobile-devices/what-is-ma...

It is double-edged sword. Adds new attack vector to compromise the whole phone. Is the user data encrypted when the maintenance mode is on? Can thiefs access it and make phone usable?

The user partition is encrypted by default, so a Maintenance Mode user has no access to user data. Maintenance Mode can only be enabled if the device is unlocked, so a thief could only enable it if they have your device password or they grab your device while it's unlocked; obviously that's a more general attack vector. The device can still be remotely located, locked or erased while in Maintenance Mode.

How would the transfer work with a completely dead screen on the old phone?

Wait for it to do a fresh backup then nab it on the new phone would be my first try E: no wait I'd just plug it into a computer

and enter passcode how?

The iPhone transfers card details to Apple Watch automatically, so no, that data is not stored in a non-exportable fashion. The data-storage capacity of things like a TPM or Apple's secure enclave is absolutely tiny (e.g. the TPM specification[1] only requires ~7KiB) - which makes sense considering it only needs to store a handful of encryption keys and other stored-secrets. [1] https://trustedcomputinggroup.org/reso…

Cards on an Apple Watch are provisioned separately from those on a paired phone. They have different card numbers, and are provisioned as two separate passes, each with its own fraud control. Once a pass has been added to one Apple device, a reference token to that physical card is added to your iCloud account, which can be used to initiate the provisioning flow on other devices. Usually that token requires at least…

Ah, so that's how it works, thank you for the clarification.

>Is the user data encrypted when the maintenance mode is on?

Yes, the primary device user data remains encrypted. The temporary user functions in a sandboxed state.

>Can thiefs access it and make phone usable?

The expected functionality prohibits access to the primary user data. Even if they were able to break from the sandboxed space somehow, the primary user data maintains an encrypted state.

You should delete all your personal data and then leave a mobile in the support store, I won't leave my phone unblocked to anyone.

I get why you’re being careful, but following on from your logic there… there’s nothing from them also adding in some root kit. Depending on your level of carefulness… I would consider your phone not secure if it’s confiscated and you’re not in the same room as it.

Following the same logic, you should never buy a phone used in case the previous owner installed a rootkit, and may also want to worry about rogue factory workers installing a rootkit before packaging the phone.

I think running a system restore should make the phone reasonably safe?

Lots of people seem to be misunderstanding this post. Apple is not asking for the posters password, they are asking for the poster to disable a function, which can be disabled online and offered a device to do this. They were not offering the device to capture the password in order to perform maintenance.

Poster is concerned about entering password on a device used by many. Poster could go home log on to iCloud on a device they own and disable Find my from there. No passcodes handed over. No access to device data, remains encrypted.
