Encrypt Backup Password Problem

I checked the option to encrpyt the back up using a password. Any password I try cannot be used - I've tried my itunes password and a variety of others - I just keep getting a message saying the password cannot be set. It worked fine until a couple of days ago. Any ideas?

Had same problem but I didnt have a keychain iphone backup file nor could I enter a password in itunes, found this possible solution if you have previous back-ups

On a mac:
1- Make sure you have a previous back-up
2- Make a new back-up of the phone in its current state
3- Go to <username>/Library/Application Support/MobileSync/Backup
4- Find the most recent backup of your phone as well as the one you want to restore to(previous Backup).
5- Open the Manifest.plist file for each
6- Copy the value in BackupKeyBag from the new one to the one you wish to restore to.
7- Save.
8- Restore to the old backup!

Thats all well and good for Macs, what about PC's?

Nothing suggested so far has worked.
Basically I did a backup without setting a password and now when I go to restore it requires a password (or passkey) I never put on it. All of my known passwords don't work and programs like elcomsoft havn't turned over anything.

Serious glitch and it was my phone service provider that suggested a restore to fix my original problem in the first place.

Adding to Vicky's solution, maybe you don't need to jailbreak your phone to remove the file. You sure don't need to use SSH. Just grab iPhone Explorer, a great tool I'm always advocating: http://www.macroplant.com/iphoneexplorer/ and do everything else as he explained.

I tried open the Manifest.plist file under /Users/<user>i/Library/Application Support/MobileSync/Backup/ and search for:


IsEncrypted key (just below BackupKeyBag) and changed it to false. The restore from the backup worked but then iTunes couldn't read the

contents from my iPhone. Ended up restoring from the scratch 😟

what is the solution, somebod please heeeeelp!!

Fixed with Elcomsoft Phone Password Breaker, for all of you who posted about this, I thank you! I almost resorted to just saying "eff it.. looks like I'm going back to a new phone" 3 hours of researching before I gave up though. Finally stumbled on this forum.


What I did: (I own Windows 7)


Downloaded the Elcomsoft Phone Password Breaker, program for free.

Made a .txt file on Notepad, typed in a huge list of every single password I could possibly remember from when I started making passwords on computers.

Opened up Elcomsoft, and hit the little green " + " sign, clicked "Wordlist attack" , and hit the other green " + " sign, and added my .txt file of all my passwords.

Set it to Maximum attack and clicked GO!

~One minute later it said "Password found!" and it gave me the first two digits, but I was able to guess by how long the password was.

Boom all my precious data is returned to me <3.


For all of you who have this problem I wish you luck, because I know how annoying it can be.

I encountered a very similar problem. I had deliberately turned on encrypted backup of my iPod Touch, but found that backups were taking forever and even stalling on several occasions. So in the middle of one of these stalled backups, I decided to uncheck the "Encrypt iPod Backup" box. It asked me for my password, and no matter how many times I entered what I was 99% sure was the right password, it was rejected every time.


I finally cancelled the backup completely (by swiping on the iPod screen), restarted the iPod and plugged it in again. Then, without the iPod being in the process of backing up, I clicked the "change password" button. I entered the "old" password (the same one I'd been trying before) and entered a new password, and it worked. An unencrypted backup commenced and finshed.


One (maybe not the only) bug here is that you can't change or access that iTunes control for toggling backup encryption while a backup is taking place. Very stupid that it erroneously reports an incorrect password at that point.

I upgraded my server, which hosts my iTunes, to Lion server a few weeks ago. It had removed a bunch of settings and I couldn't afford the time to test or reconfigure it, so I restored to a backup. After restoring to a backup from right before the upgrade, some strange things happened with iTunes. (I used a a more recent backup of the library. Didn't want to lose my playcounts!)


I never recalled setting the "Encrypt backup" for my iPhone, but it was checked. I'm meticulous about storing passwords in 1Password, so I couldn't figure out why there wasn't one. I tried all my passwords. Nothing.


I just installed the new iTunes (10.4.1) and when I plugged my iPhone in, bam! No more encrypted backup!


Not sure if this was a bug or I'm just going crazy, but this isn't a problem for me anymore.


(It is taking way longer to backup since I restored to Snow Leopard, though...)

I had this encrypt password just appear yesterday ive been reading up on how to get rid of it. I was even going to throw the computer out the window. I thought i tried all my passwords that i remembered and nothing. Ive read every post on this discussion and tryed everyone solutions and nothing. Until i remembered my very first password to itunes and that was it. Im sorry if it doesnt help you but it did me and now its gone. Thank god

I was also having trouble remembering which password to enter when promted during the restore process after upgrading to IOS5. The simplest solution for me was to

1. Open my keychain (Applications/Utilities/Keychain Access.app)

2. Select passwords in the category section on the bottom half of the left-hand pane

3. Scroll down the list of passwords until I found iPhone Backup

4. Right click on iPhone Backup and select "Copy password to Clipboard"

5. Verify my authority to copy the password to the clipboard by responding to the prompt to type my Mac password

6. Paste the password into the iTunes promt (you could also paste the password in a text doc to see what it was)


Hope that helps...

Thank you so much OzoneARC!!


After 4 hours & a serious headache your suggestion worked!! I had already downloaded Elcomsoft Phone Password Breaker but without saving a txt file with possible options this was not working for me. Your walk through the process was exactly what I needed!


As mentioned the trial version only gives you the 1st 2 letters & shows the length but that was enough for me.

Yay I have my iPhone back!!!!
