Method 1: Try Possible Passwords

The most obvious advice is to try some of your possible passwords! Very few computer users actually create unique passwords for each account. Most people have one or two passwords that they use across all of their accounts. Check out the clues below and hope you can remember your iPhone backup password:

• Try your iTunes Store password, which is most commonly the password to restore your backup.
• Try your 4 digit passcode for unlocking your iPhone device.
• Try the default password 0000 or 12345.
• If you are using a Mac, check if your iTunes backup password is stored in Keychain access. First, open Applications -> Utilities -> Keychain Access. Double-click on the entry for “iPhone backup” and click “Show password”.
• Try the Windows administrator password.

If you have managed to attempt all the steps and nothing has worked, it seems like you will have to crack your iPhone backup password with third party password cracking software.
