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

I worked the password issue out.... Well this worked for me anyway


The password did turn out to be my usual password. I tried this password MANY times when trying to backup my new 4S from my old 3GS, but it was never accepted.


So I tried to change the encrypted back password within iTunes. It asked me for my old password and to set a new one.


THIS WORKED!!! Old password was accepted as was the new one I entered.


I have now totally backed by my new 4S with my 3GS data!


Though, did you know that XP is not supported with 4S, so your Mail details will not be restored. But all my contacts, messages, apps, phone call dats etc have been totally restored! Phew!

Apple support no help with encrypted backup. After over a week and endless phone calls, being passed to "senior" people and engineers and hours and hours of trying to remember passwords, I have now been officially told by Apple that they cannot help with the encrypted password issue. There are posts going back to May about this same problem with the previous software and nothing has been done about it and iOS5 was released without so much as a warning that this could happen. I believe there is an Apple site for feedback which I will be using. I am copying the encrypted backup to an external drive and possibly later I might be able to guess the password or Apple may come up with a solution to what really is a bug in their software (as much as some people will deny it) Then I guess it's "restore as new phone" with loss of important photos and notes.

If you have selected back up from previous restore- when you get the dialog box asking for the password, press the escape key. In my case, the iPhone then started backing up from my previous restore, no password needed. I did have to loop back and clean up a few things, such as manually re-adding Favorits in the iPhone app, but everythiong else was there. Try the escape key trick and you should be OK.

I agree. The solution (for me at least) is to keep trying the same password that I know is correct. For me, the fourth try of typing in the exact same password works in iTunes on my iMac. I have repeated this several times, and each time it works.


What is messing people up is that when iTunes does not recognize the correct password, people are attempting other passwords. Those other passwords are all incorrect. The problem, as you stated, is that the password was entered correctly the first time but because of iTunes having issues it does not recognize it.


People, just keep entering the password you know is correct. It will eventuall recognize it, or at least this works for me. If this still does not work, reset your password (but then you may still have to enter it repeatedly in iTunes).


Apple needs to fix this.

I had this same problem with my iPad backup and the solution ended up being the most random, unrelated password possible.


After trying every password I could think of and all of the ones suggested in this thread (itunes account, computer password, 4-digit numeric unlock password for the iPad, variations with and without the numbers, 1111, 0000, 12345, etc), I finally tried elcomsoft to help crack the first two characters.


The password to unlock and restore the backup for my iPad ended up being a password that I usde to encrypt a Blackberry backup about a year ago.


If this was a password that I normally use, it might make sense. However, what weirds me out about it is that I am 100% certain that I have only used that Blackberry backup password once in my life, for a specific reason (it wasn't my phone so I made up a random password for it). I did it once for that phone's backup and never thought twice about it.


Thank goodness for elcomsoft and I'm so glad I was able to restore...but how did one (non-apple) device's backup encryption end up affecting and locking down my iPad backup? I have no clue. Pretty creepy.

gev.iphone is definitely one to try. Wanted to update my iphone4 to iOS6 and I tried EVERYTHING!!! Every password I could think of, old and new for my pc/iphone/Facebook/1234 & 0000 several times and NOTHING worked, even tried the disconnect and cancel as suggested by gev.iphone in their post. Had saved photos prior to update (backed up phone but had copied photos into a file on my pc separately as well) so finally gave up and disconnected the phone deciding that I was going to try my iPhone's option of "start as new phone" rather than back up via iTunes or iCloud and once I had reset the language region etc the phone stated it should be connected to iTunes, did and it sync'd automatically, restoring all my apps, contacts and notes from my notepad and is working perfectly. The only thing it didn't restore was my media. It did warn of this when the update was performed. Make sure you save your photos etc separately out of iTunes. Also, updated my iPad's OS as well and it lost nothing nor did it ask for any password, did it automatically through the settings and not one issue. Have to agree with most on here, apple sort it out!!

Bought the wife a new iPad for christmas and hey presto. Same problem when I tried to restore her iPhone stuff to the iPad.

We've never setup these encrypted passwords. After trolling through the internet for a fix, here's what worked for me.

On her iPhone backup i typed her iPhone name. IE Julie iPhone. I typed Julie. Great it worked.


However, I decided to check my own iPhone. And it had the same encrypted backup problem. I tried typing in my iPhone name but it didn't work. When i typed in the PC logon password it did work.


I know apple will never admit to it. Its clearly a big bug in the system. I wish you all the best of luck and hopefully what i've done will help you

As frustrating the problem was becoming, your suggestion worked like a miracle for my iPad 2.


I was upgrading my iPad 2 on my Mac to iOS6 post which all this trouble began, when I did not set any password for backup, iTunes was asking me for a password to unlock the backup restore !!!!!


Finally after reading and trying a lot of solutions from this thread, what worked for me was my iTunes password all in small and without numbers, phew !!



All the best to you guys.

I just solved this after two days of trying every password I've ever used in the past 10 years with no success and lots of frustration. Apparently the password is somehow connected to the apple.com cookie


- exit iTunes

- open Safari and clear all cookies

- restart iTunes and connect your phone

- uncheck the encryption box and enter your AppleID password at the prompt. (Or your phone lock code if the password doesn't work)


This should release the encryption

Ok this for all of you guys who have no idea what password you set up.


First i will provide a photo of the main screen you should be looking at.


User uploaded file




1. When you first plug your phone in you will have your back up window come up with different options.

2. In the Back up window under (automatically back up) make sure (this computer) option is ticked

3.Just below it there is an option to tick (Encrypt iphone back up) tick this option.

4. A window will pop up asking you to set a new password.

5. Set up Password and click (set password) to confirm. IMMEDIATELY CLICK CANCEL STRAIGHT AFTER. what this does is overides whatever password you had before but stops the phone from syncing new data.

6.Now you can click on restore back up and when it ask for that stupid password just type in the one you set up in step 5.

Hope this helps

the password that is asked for the restore backup is a previous lock screen password (4 digit passcode).

I say that based on my issue as I tried a trial software called: iPhone Backup Unlocker Standard, and it helped me to remember one of my passcodes (cuz it told me 2 digits out of 4) that I used to set on my iphone.
by the way I faced this problem when I updates my ios from 7.1.2 to 8.1.2.
