Q: I can't restore my backup because I don't have the encrypt password. Any suggestions?

what did you encrypt it with?

If you can’t remember the password for my encrypted backup

You can't use an encrypted backup if you don't have the password.

When you try to use a backup, you might see a message saying "The password you entered to unlock your backup was incorrect." This message means that the iTunes encryption option was turned on in the past by:

• Yourself
• Someone who set up your device or transferred your data to a new device
• An installed profile (for business or education devices). If you're using an installed profile, contact your system administrator.

If you don't have your password:

• If someone else set up your device, check with them for the password.
• Try using an iCloud backup instead. If you don't have an iCloud backup, you can make one.
• If it's still relevant, try using an older iTunes backup.
