iTunes is a little quirky, to say the least. It often does unexpected things or doesn't do what you expect it to. You might never have set a password for iPhone backup, but when you try to restore from the backup, it asks you a password to unlock the backup first. What can you do in such a situation? Is your iTunes backup lost forever? Thankfully, there are a couple of ways in which you can still access it without the risk of losing valuable data. First, however, let's cover the basics of iTunes backup encryption first.
Part 1: FAQ about iTunes Backup Password
Part 2: Guess All Possible Password
What is an iPhone Backup Password? When you take a backup of your iPhone data using iTunes, it may automatically encrypt that data depending on your settings. If the little box next to Encrypt Backup is checked, you'll end up with an encrypted backup for which you need a password when you want to restore or just view it.
How does iTunes backup encryption work? An encrypted backup is a little different from a regular backup because it contains your health data, saved passwords, Wi-Fi settings and your web history.
In iTunes, the backup files are encrypted using AES128 with a 256-bit key. Alternatively, it may use a 128 bit key in conjunction with Cipher Block Chaining, or CBC. This is somewhat similar to the technology that Microsoft uses to hash Word, Excel or PowerPoint passwords, and it also uses the same SHA-1 hashing algorithm. In the case of iTunes, the key is stored in the iPhone Keychain.
What's the default password for iTunes backup? Actually, there is no default password for iTunes backup. Either is blank or encrypted by a password the user set previously.
Why iTunes asks for a password to restore backup? When the backup file is password protected by iTunes, you have to input the correct password to unlock the file to prevent illegal access to user's private data. If the backup was not encrypted, then anyone could retrieve user information from it with third-party tools.
The password you entered to unlock your iPhone backup was incorrect? It means the password you entered didn't match the password you set initially. You have to get the correct password to unlock the backup.
Most users of desktop and mobile devices today tend to keep using the same passwords over and over again for different accounts and applications. This is unsafe practice because if one account is compromised, it's easy for a hacker to unlock all your accounts. Even if you use variations of a single password, it's much easier to crack than if each password is long enough and unique enough. The problem is, using such passwords leads to forgetting them.
So, if you're one of those users, you can try various combinations of passwords that you typically use. Here are some ideas to recover iTunes backup password. You can try out variations of these as well:
