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

With all due respect, Llenooo_xx you are wrong and lucky. If you would read the hundreds of responses to this thread, you will see that each and everyone of us tried the password we always use. 99%'of the time the correct password turned out to be one we DON'T always use. That's the problem. In my case it was a password that belonged to my middle daughter's Facebook account and my oldest daughter was syncing on a computer that the middle daughter never touched. This is why this. Bug is so ugly, it takes some random password that you may have on,y used once and some times one you have never used with iTunes or your device. Which boggles the mind that apple has not addressed this yet.

Hi


The latest version of itunes has an option where you can set the password for backup. If you check that option, it asks for a password. You can set a password, and then it will encryp the subsequent backups with that password, and you dont have to go through the pain that a lot of people had to go through.


I just updated my wife's iphone 4 from iOS 4.4.3 to iOS 6. Before the update, I updated the version of itunes to the latest. Before installing the new iOS 6.0 on the phone, I set the option to password protect the backups. I think it is on the "general" settings page when you connect your iPhone. It is a little low on the page so you might have to scroll down.


Good Luck.

And I am 100% sure that I tried this one for a hundred times yesterday!


Hi. Sorry to be blunt but you didn't. Not only did you set that password all that time ago but you, 100% sure, didn't input it correctly any of the times you tried yesterday (which I'm willing to bet weren't a hundred times, but it's not important any way).


Everyone in this thread must understand this:


You or someone in your computer set the password you insist you didn't.


You didn't type it correctly any time you think you did, when you tried before and it didn't work.


Apple not only doesn't know your "other" passwords to be able to use it here, but it doesn't even know your Apple passwords. Encryption doesn't work like that and even if it did, encrypting local backups has no realtionship to what apple does remotely.


As I said, I'm sorry, but this thread was already sad before people started insinuating upgrading is a bad idea due to security. This is ridiculous.

If I had your device there's no way I'm getting any information out of it without your passcode or finger. Sure there are tools out there to hack into the device, but not available to the average dirtbag. Without your passcode or fingerprint, no one's getting in. However, your computer may or may not have the same level of access restriction, hence the option to encrypt the computer's copy of your backup.


"However, your computer may or may not have the same level of access restriction" - If you elaborated on this it might lead somewhere.

I thought I had and I wish I had the option to encrypt the computer's copy of the backup. That's what I thought I turned on. However, this option apparently also locks out my ability to create unencrypted backups in the future. The option does more than one thing, and it doesn't tell me that it is doing the 2nd thing, and it permanently locks me out without giving me any warning.

Apple doesn't need to mention anything because it is quite evident that applying encryption requires you to remember the password (hence the requirement to verify the password you chose when you set it).


I agree that it is quite evident that applying encryption requires me to remember the password, in order to decrypt whatever I encrypted. In this case, I was encrypting a local backup on my computer. I forgot the password and I fully accept that I cannot decrypt the backup (if I still had it).


You seem to be confused ... encrypting your backup does not make your device inaccessible or locked out for normal use.


I am fully aware that I have not been locked out for normal daily use, as I have been using the device daily for years. I would think that making unencrypted backups is also normal use, and I should not be denied that normal use simply because once upon a time I encrypted a backup on some computer that I might not have anymore.

Your computer analogy does not apply to this scenario at all ... name a situation "in the normal computer world" where if you password-protect some information that you still have the ability to access the same (protected) information without the password. In some computer situations there are password recovery options, but not in situations where you, the user, assign and administer the password yourself.


This isn't that complicated. If I have a server and I create a backup of the server on my local computer, and I encrypt that backup with a password, then my server is not encrypted; only the backup on my local computer is encrypted. Of course I can't access the backup without the password. However, my backup software would not encrypt (or cripple) my server without asking me to. That would be insane.

Well, I guess if you're ready to forget all your settings and start fresh, you can always delete the backup. Disconnect the phone from your PC, reconnect it and, when iTunes comes up with the "...interrupted while restoring..." message, use the "Delete Backup" button. I haven't tried it but I guess it will do the trick.

Personnally, still working on the password thing... and hoping for Divine intervention 🙂

Thanks Gremlin 13 for telling your "adventure" with support.


I still hope that a future version of itunes will solve it, although it is an older problem, there are messages explaining this since last year, like :

password for my backup


But most (and there are more than 100 threads, most of then short-lived) are from the last weeks, after ios5.


I have tried using an utility to search for the password of a itunes backup, but, as has happened to other people, it says it is unencrypted, so this seems to be a very big/bad/ugly bug.


Also there is an utility to look at backups that seems to have help some people :

http://download.cnet.com/iBackupBot/3000-18551_4-75532275.html?tag=contentMain;c ontentBody;2d


Not really useful to me, as I did a sync, and that seemed to produce a new backup that overwrite the old one (without asking, of course).


But when connecting the iphone it keeps asking for a password to continue the restore...


I have put a new password on my new backup, but that doesn´t works, itunes keeps asking for the password.

I have also tried all passwords on the keychain, and some out of the keychain, but none works.



Good luck to all.

Nov 10, 2011 12:20 AM in response to hamayon

No, it isn't the user login password of the machine that you last synced your iPhone on, at least for me!


I've founded that it was the password of the computer that I synced for the first time (I don't have that computer anymore and I have never synced this device to that computer!!).


I've used my old iPhone 3g on that computer and then with the backup I've synced all the data on my new iPhone 4 white.


I really don't know how it takes the password automatically, maybe I think that at this point the Apple support can provide a clear answer to this problem.

Jun 23, 2012 1:46 PM in response to wsucoug95

Neither 0000 nor 1234 worked for me. I got so scared. Then I tried 'littlemonster' or 'ladygaga' (passwords I put on vague websites) That also didn't work.


Finally, I tried my name in small letters, and IT WORKED LIKE MAGIC!


So I'm just *guessing* the password can be your *Apple ID(iTunes) password* without numbers and special characters. Might be. 🙂

This undocumented scenario is just unfathomable. The amount of grief, lost time, and great stress is something to be held against Apple. This is a deep black eye for them.

Yes, I ran into the same problem doing an upgrade to 5.n. Never asked or gave a pw, but required it to restore. What the...

After reading this thread I figured out that the pw was my original pw on the phone. But since that does not seem to always work for everybody, I am thinking it is the pw on your phone at the time you do your first logon to istore, or the first time you sync or something like that.

Good luck to everybody.

It happened this morning. I updated my iOS to 5.1 and it made a backup as usual. I never EVER provided a password for all my backups of iOS - Devices - this is the first backup on my MacBook Pro which all after sudden is encrypted and I DID NOT provide a password and I DID NOT check the encrypt my backup - box.


I tried to restore my backup for 4 hours and I finally gave up. I used my Apple-ID password, my Mac - Password, my iPhone-Unlock-Screen digits - I used 0000 , 12345, password , Facebook - Password , Email-Password, Banking-Password .... NOTHING worked.


This bug seems so random it is unbelieveable - so I keep the encrypted backup and hope that APPLE comes up with a solution - this is unbelieveable - I've lost my pictures and some other data. I've read here that some guy punched in his iTunes-Password for 4 hours and suddenly it worked - what the f.... is that ?


Apple has to come up with a solution and be upfront about this Bug - this is unbelieveable. The responsible manager and developer have to be fired right on the spot.


I'm a Software Engineer too - but not to test such a important feature is a absolut NO GO.
