iTunes asking for backup password???

I am upgrading my iphone 4 to iOS 5. I backed up my phone (via iTunes 10.5) and downloaded and installed iOS 5. I am now going through the setup process and it is at the "Restore from iTunes Backup" step. I connect to iTunes and iTunes is prompting me for a password to "unlock your iPhone backup file." No I did not encrypt the iPhone backup, nor is it or was it checked in iTunes. I have tried my iTunes password, my 4 digit unlock code for the iPhone, and several other passwords. When I did the backup an hour ago I was not asked for a password. I am at a loss as to what it is.

Guys, here is our experience with this bug (and yes Apple this is a bad bug not a bad memory) and here is how we got around it.


My wife recently attempted to upgrade her iPhone to 5.1.1 and iTunes advised her that she would need to do a complete backup and restore process on her iPhone which she agreed to and let it start. So it did the backup, upgraded her iPhone and then when it attempted to restore the backup it halted and asked her for the password for her encrypted backup. As other folks have indicated, she hadn't requested this backup or any other backup in the past to be encrypted, but regardless we could not proceed beyond this point. We tried every combination of password she or I had ever used with no avail. We also spent hours with the Genius Bar folks and the online Apple support folks and received plenty of empathy but no results. You really are left with the impression that this is your fault and that somewhere in your dark past you or someone in your family encrypted a backup with a password.


So we went the Elcomsoft password breaker route which some folks here have used with success. i would like to share my experiences here because I feel I owe this forum a favour and also to make sure you know how to get this software to best work for you ,because even though its very powerful, its not totally intuitive.


First Attempt - We downloaded the Elcomsoft free trial version of the software, told it to run, asked it to go against our iPhone backup file, selected the most recent iPhone backup (btw this wasn't that days but instead was one from 2 weeks ago - another bug Apple) and told it to start. When it starts, it will tell you how long it expects to take and in this case it said 4 hours. As the Elcomsoft software is running it says what its "attack rate" is of approximately 700 password attempts per second and it displays its current attempt every second so you can see it work through the possibilities. In this case, under their "task" I had accepted the default "english dic - no mutations" So with this default it just attacked with standard unicase dictionary words and after about 2 hours it finished with no success.


Next Attempt - I wasn't suprised and decided to look deeper. If you double click on "english-dic" it will open a box showing your selection and displaying the mutations options "disabled". if you click that, you can see that you also have the options of minimal, average or maximal mutations. I chose "maximal" and it in turn advised me that it could take up to 4 days to run this attack! So I quickly backed off from that and chose "minimal" and it in turn advised me that it would take up to 30 hours to run this attack. I chose this solution, but before running it on my wife's backup, I ran it on my iPad's backup on a separate computer where I intentionally protected it with a password of "1234". Off it went, and you could see it apply different combinations of numbers, letters and special characters. In was kind of fun to see and in less than 2 minutes, it found the password and came back showing 12**. If you want to see the ** characters, you then need to buy the application at around $80 and get a registration key.


Successful attempt - So with that little success under my belt, I started the "minimal" attack on my wife's computer and her iPhone backup. And 25.5 hours (it said it took 91,871 seconds) later it was successful and showed the result as Pr*****. So at this stage, you could try variations of Pr and 5 characters, but since we had never encrypted our backup and also never used a password beginning with Pr, and because Elcomsoft was going to save us a lot of grief if we had to leave the iPhone at factory settings, we elected to register the software and proceed with payment. Success!! Her phone is now on 5.1.1, all her application data is in place and we have a happy household and I am a hero!


Learnings - #1 - Encrypt your iPhone/ iPad backup intentionally with a password you selected vs. letting some bug somewhere select it for you. #2 - Make sure all your important passwords such as your PC or MAC signon and your online banking software are secure and complex, because this type of software is very powerful and there are a lot of bad guys out there that will use it for the wrong reason. Elcomsoft has provisions to protect it from being used for the wrong purpose, but others might not. During those 25.5 hours, I estimate it attempted over 64 million attacks! #3 Elcomsoft is in Russia! So it will take a few hours to process your payment since they don't seem to work 24/7. So kinda of scary, but it worked.


Thanks

Fred

Hi

I faced two problems with my backup file, first one it was corrupted and I couldn't to restore my files after I erased my iPhone 6, I searched and tried many ways and many specialists to fix my problem, by internet, after nine hours on it, I found a program fix the corrupted backup files, I tried it but when finished I faced the second big problem and it added corruption to my files and if I purchase the program it will fixing the corrupted file and remove any encryption on it.

I purchased the program with Amoun 60 US Dollars, and it fixed my big problems.

Come on, Apple!

This was posted six years ago and you still haven't fixed it.

Just encountered the same issue, and the posts in here were really helpful. But it was pure luck that I remembered my old password from over a year back. And it's not correct as some people here say; the correct password is one that I am not using on ANY devices or services at the moment.

There is nothing to fix. The first time you make an encrypted backup you enter a password - twice. That password never changes, because it is actually the seed that creates the encryption key. It can be a password that you never used on any device for any purpose (mine is). But it is a password that you entered. There is no other way a password can be set on an encrypted backup.

I don't know who you represent, but from your reply I have learned that we are talking about a password I entered 4-5 years ago.


To me Apple is all about intuitive UI. And that is NOT intuitive UI. Not even close.

I don't know what message or information I was given some day 3-5 years ago when I was asked to enter this password. But Apple usually makes sure that I understand what I'm asked. To ask for a password that I was asked to construct many years ago, without ANY further information, description or explanation is just far fetch. I made my way out of that situation because I am a freak when it comes to remember random information like that. Any given user would just

A: be lucky to have that password still

B: be patient enough to go through any password he or she has ever used.


If you think that is not a UI-issue that needs to be fixed (a simple explanation would do it, when prompting the password), I hope you don't work within the UI-field.


Anyway, thanks for the explanation. I've fixed it, so I'm kind of done with this subject. I was just hoping that someone from Apple would take this thread with 1200+ other people having the same issue seriously.

Encrypting your device's backup does not require your password to initiate another (encrypted) backup ... you are only prompted for your password if (a) you want to turn encryption off, or (b) you go to install the backup back onto your device after erasing it. You arenot prevented from making backups to your computer even if you don't know the password, so how exactly is your device crippled?

I am prevented from making unencrypted backups to my computer, and I am also prevented from making encrypted backups to my computer using a new password.


You're not telling the whole story here. So what did you do, change computers? Change hard drives on your computer? Delete the (encrypted) backup file? (I'm not sure that would lead to this) If you're not trying to turn off encryption or install the backup, these are the only things I can think of which may prompt you for the password which you forgot.

I don't know what happened to the backup file. I think I probably reinstalled my Windows since I made it. I may have also deleted it once to save disk space.


Normally, the only thing that should require a password after encrypting something is when you want to decrypt it. I don't want to decrypt it, yet it still wants the password from me.

OK, I will make it simple and clear (although this has been covered ad nauseum in the thread):

  • If you have an encrypted backup ("Encrypt Backup" is checked) it is encrypted because you or someone else checked "encrypt backup". Period. That is the only way it can become encrypted.
  • The "someone else" can be the administrator of a Microsoft Exchange email server if you have a company email account on your phone. There's at least one case where it was someone's daughter.
  • The first time you back up after it is checked the person who did the backup had to enter a password. Twice for confirmation.
  • The password entered that first time will be the backup password forever, unless you explicitly change it; even if it was entered 10 years ago. It will stay the same.
  • The password is more than a password; it is the encryption key, and is saved in the encrypted backup and the iOS device.
  • There is no way to bypass encryption, except to enter the correct passcode.
    • Backing up to a new computer will not bypass it.
    • Deleting the encrypted backups will not bypass it.
    • Buying or downloading software that claims to bypass it will not bypass it.
  • The good news is that you get unlimited guesses, and to speed up the process of guessing, uncheck Encrypt Backup and you will be prompted immediately. Most people who have succeeded have found it was a password that they had used elsewhere.

Someone gave me the solution that worked for me. Turns out I had indeed set up a password years ago, as the lock icons I mentioned suggested, and completely forgotten -- and the reason I was able to completely forget this is that Keychain was providing it to iTunes whenever I did a restore. So I didn't even have to know this was happening.


What was inexplicably different this time is that something must have happened to Keychain or iTunes (either due to an update, glitch, or some new setting) that severed the connection between the two. iTunes didn't even offer to ask for permission to use Keychain. So I manually retrieved the password from Keychain, typed it into iTunes, and it worked.


I then checked older iPhone backups in iTunes, and interestingly, they did still automatically retrieve the password from Keychain. Only the newest one failed. No clue why.


But perhaps this is what happened with other folks, who didn't recall they had a password because it was being accessed automatically in the past. Check Keychain for passwords on older backups, just in case.

i have got a new iPhone 5 as a replacement for my old one.

before resetting my old one i had created a back-up without password.

iTunes asked me for back-up password when restoring the back-up on the new iPhone 5.

i tried applying above procedure on the new iPhone but did not work.

then i tried to restore my old iPhone with above procedure and it worked using my Apple ID password.

will now make a back-up with password :-) and copy it to the new one.
