Shifting the phone number from the original iPhone to this one can help with two-factor authentication and password resets. Contact the carrier to find out about moving the phone number. You may need a PIN for the carrier, power of attorney for someone incapacitated, or a death certificate and proof of executorship or other power. Although you cannot restore an encrypted backup without the actual password for it, you can create a new encrypted backup of your device with a different password by just resetting the password from your iOS or ipadOS device.
Simply follow the steps below to get started. There you go. Now, you can just simply connect your iPhone to the computer using the included Lightning to USB cable and create a new encrypted backup of your device in iTunes or macOS Finder. Although we were focusing primarily on the iPhone, you can follow this procedure to reset the encrypted backup password for your iPad or even iPod Touch, if you still have one lying around. We hope you were able to reset the password for encrypted backups from your iOS device.
If you own a Mac, did you try recovering the password first using Keychain access? If you've lost or forgotten your iTunes backup password, there are a few techniques you can use to try to recover it. First, it's worth trying a bunch of passwords that you might have used.
There's no penalty to trying a number of different passwords in iTunes, although each check can take a little while. There's no such thing as a default password for an iOS backup. Passwords are set on the device, not by your computer. If your device was bought or configured by somebody else, it's possible that you need to ask them for the password.
If you use a Mac and configured the iTunes backup password on that Mac, your computer may have kept a record of the password in its keychain. Searching the keychain for a backup password. There's also a nuclear technique for removing an iTunes backup password setting from your device. Enable iCloud backups under settings, back it up, then erase and restore it. This process is long-winded -- especially for users with a lot of data or a slower connection -- and ideally avoided.
You can see our guide to making an iCloud backup to follow this approach. Backing up to iCloud. Apple provide technical details on how encrypted backups work. That makes checking a single password slow enough, even if it's the right password. Trying many different passwords with a tool like hashcat is a very slow process. Users can export a hash from their backup for use in hashcat with our free rictl tool with the following command:.
Assuming the password had 8 digits, limited to only upper or lower-case English letters or numbers — and no punctuation symbols — there would be ,,,, 62 8 possible combinations. That's substantially before the heat death of the universe, but it's still a long way away.
Thus, from a practical perspective, it can be possible to recover a password if one has a general idea about its form, such that a few hundred or thousand guesses would find it. You might be curious about working with a university with access to quantum computing resources. Whilst there are quite a few click-bait articles out there on the amazing powers of the technology, it doesn't make cracking strong encryption much easier. There are two good resources on this: this sober paper nicely summarised by The Register : "Grover's algorithm would need about 10 32 years to crack SHA".
Then there's this, less sober article , which suggests that even if one were to build a Dyson sphere and capture all of the energy radiated by the sun it might still be hard. There's another approach that might be faster than general quantum, and that's using an ASIC. This is essentially a custom piece of hardware that is designed specifically for the encryption algorithm one wants to break. This is independent to your Apple ID or other passwords. Your Mac stores the password in the login Keychain and uses it for future backups.
