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

Not at all, just a password that contains upper case, lower case and numbers. If you don't know what we are talking about on here maybe you should stay out of the conversation?

I backed up my phone as usual, itunes never asked for a password, it is not encrypted. Then after restoring the phone i tried to load the backup I had just made 5 mins ago and it asked for a password. 1234 did not work, 0000 did not work, windows login did not work and more importantly my Apple ID did not work.

Thanks, someone being helpful.! I don't remember setting this password but like you say it much have been months maybe a year ago. I looked at my iTunes and the encrypt backup is checked which I also don't remember doing, I've never used this feature but that would make sense, I've checked it at some point in the past and set a password. Thanks for helping explain this. Daz.

Wow, you must be a crazy apple fan! First of all I absolutely did not encrypt my back-up. I specifically backed it up the same day knowing I was going to use it. Secondly, read the thousands (if not millions) of posts from others that did not set a password or encrypt the back-up. I suppose we are all idiots and did not notice that we selected encryption! Apple never makes mistakes!

Lol. So what your saying is software that remembers something I did 5 years ago verses what I did NOT do 20 minutes prior to restoring the back-up is my fault. I see you logic. That is not a software issue at all. the Apple tech supervisor I spoke to is also using your logic. "We have no known problems" but yours (and others) must have glitched". Lol. So much denial. Just like the tons of people experiencing issues with the latest iOS (10.2). I guess it is my fault that my phone drains in less than an hour and my fault it shuts off at 30%, apps not loading, etc. Lol. Yup. Apple is perfect.

Weird situation. I just erased my phone and am restoring it. I only back up to iTunes. I tried restoring, and it asks me for this password to unlock the iPhone backup. Like others here, I have no recollection of ever setting that up, and "Encrypt iPhone backup" is indeed unchecked in iTunes. I've tried every password I've ever used with Apple, to no avail.


Weirder: I see that in iTunes/Preferences/Devices, the "lock" icon does appear beside the visible iPhone backups going back a couple years. Which suggests they have been encrypted.


But even weirder: I just replaced my iPhone 4 months ago, and was able to restore it from the iTunes backup without entering any password -- just as I always have.


I can't figure this out. Private computer, nobody else has access. Even if I had set this up years ago and forgot, how could I have been restoring without a password until today? Meanwhile, I seem to have lost a lot of important stuff.

See in my case I know I checked the box. However it did not ask me to enter a password, so how the **** do I know which one Itunes used? I see in some of the other comments that it used a password that was super old from an old itunes account and all that crap. Well if that is the case I have had iphones since the 1st one. I changed that password like 5 years ago and have always used the same one. That password doesn't work, my old one doesn't work, and my work one doesn't work. I use the same 4/5 passwords for everything. It is none of those, so how do you know? I think being condescending about the password issue isn't necessary and talking to people like they are stupid is also not necessary. People are panicking because everything they have is on there.

Thanks pjlove. BUT why does iTunes not tell us this!! 😠

Because it is WRONG. If that's the passcode the only reason it is the passcode is because it is what you entered when you made your first encrypted backup. You had to enter it TWICE to confirm it.


Anyway, iTunes has no idea what your backup passcode is, so it couldn't tell you anyway.
