iOS 16.1 requiring passcode EVERY time a backup/sync is initiated

Since upgrading my iPhone (14 Pro Max) and iPad (2021 Pro) to OS 16.1, both devices now require me to enter my passcode EVERY time I plug them into my 2020 iMac (Ventura) to start a backup/sync.


This is new behavior. My Mac is a "trusted" device; I should not have to enter my passcode EVERY time a backup is initiated.


Since Reddit is filled with similar reports, I'm wondering whether this is a bug or an intentional new "feature." If it's a "feature," it's an unnecessary and intrusive one.


I've tried all the "tips" found elsewhere to fix this (using a different sync cable, resetting my iPhone, etc.). Nothing works.


Anyone have any thoughts?

iPhone 14 Pro Max, iOS 16

Apple generally doesn’t make security optional.


Here is the identified vulnerability:


Available for: iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, iPad mini 5th generation and later

Impact: An app may be able to access iOS backups

Description: A permissions issue was addressed with additional restrictions. 

CVE-2022-32929: Csaba Fitzl (@theevilbit) of Offensive Security


Apple does not include details to prevent hackers from using it as a recipe to hack devices that haven’t been updated, but the details on how to take advantage of this vulnerability are widely available on the web, published by the discoverer of this vulnerability. And they’re scary; it’s very easy if a hacker has access to your computer. And most hacks of computers are undetectable to the user. You can find the full report on github if you know how to access it.

This is a new security measure. Investigators found that a hacker who had access to the computer used for backing up an iOS device could force a backup to an unprotected location on the computer, where it could then be downloaded and its contents compromised. So the “trust” requirement was added to verify that the phone’s owner was initiating the backup.

I never said they were infallible. I have reported why they made the change. You are certainly free to believe they shouldn’t have added this protection to your phone’s data, but you would have to take that up with Apple, not with other users in this user-to-user forum.


If you want details of the vulnerability you can find them in these two links:



Both the discoverer of the vulnerability and the security team at iMazing believes that the change was needed (as do several other cybersecurity specialists).


You can certainly argue that these experts are over-reacting.

Apple is not the customer though, I am. Breaking/regressing your product because of edge case hypotheticals is frankly cowardice. And as we keep *repeatedly* stating to you, there is an option C, which Apple could have easily implemented.

It is not “hypothetical” - it is a REAL vulnerability that has been demonstrated. And there is no point in discussing what Apple could have done. And how do you know Apple could “easily” have implemented it? What they did was a quick solution that would be highly unlikely to break something else; it was just changing a flag that says the iPhone is trusted. Anything more complicated would have required more significant changes that would have had to be extensively tested, to avoid introducing an undesirable side affect that could break some number of the 2 billion iOS devices in use. It would have taken weeks, or longer before a more robust solution was deemed safe to deploy, and once a vulnerability is public it must be fixed immediately, or hackers are certain to exploit it. I have confidence that Apple is working on a more user-friendly solution, but addressing this vulnerability could not wait.

Also this sort of user hostile decision making on Apple's part is why more and more of us are gunshy about updating. This is regressive behavior.

Yet you would almost certainly sue Apple if your identity was stolen because they had not performed due diligence to protect your data from a known vulnerability.

I never suggested that the experts are overreacting; again, you're selectively ignoring my underlying point and falsely positing this as an "either/or" situation. As has been pointed out here and in many other online forums, the vulnerability absolutely needs be addressed… but it could easily be addressed without such a draconian measure.


The solution is straightforward: Apple could provide a checkbox that reads "Require passcode every time iPhone is connected to computer for backup?" The box is checked by default. If the user UNchecks this box, a warning pops up: "WARNING! Unselecting this option could potentially lead to an unauthorized computer user obtaining access to your phone's backup data. Are you sure you want to continue?" and then a prompt requiring an admin password.


This is the same level of optional security that Apple provides many other places on the Mac.


As has been suggested elsewhere, the fact that Apple is choosing not to provide this option in this (and only this) particular case is likely due to the fact that they're attempting to drive people toward iCloud backups, and thus paid storage plans.


FWIW, I have taken this issue up directly with Apple, as have others.

Well at the very least Apple could give us an option to turn on or off this "security feature". My guess is they may want to push people towards Icloud backups for the revenue .. wouldn't put it past them after the battery fiasco (until they were caught and forced to offer battery replacements and did it for a reduced cost initially).


I am very careful about what I put on my computer so I find it frustrating that every time I sync my Iphone now it prompts me (and some times it doesn't prompt like this morning where I was forced to close iTunes and reopen it then initiate a sync again and that time it did prompt me).

This is a false dilemma fallacy. Apple has made a lot of security measures on the Mac “optional,” such as the option to install software from unknown sources, etc. There’s no reason why they couldn’t inform users of this particular situation with phone backups, and then allow the user to choose whether or not they want to turn on this added security precaution. The idea that users would then “sue” Apple after making such a choice is ludicrous.


Look, we all love Apple, but your apparent position that they’re essentially infallible in their decisions is a bit suspicious.

Jan 8, 2023 6:03 PM in response to Lawrence Finch

This is a badly thought out comment, and I encourage you to do better. I personally am not litigious and have a dislike of the legal system, but perhaps you're projecting? In any case, you dont speak for me guy. Im a 30+ year Apple user.


In any case, as Numbr007 alludes to, this could have been implemented in a far less ham handed fashion, but unfortunately this sort of move is entirely on brand for Apple lately.
