Trying to restore an encrypted backup but it says the password is wrong, I know it is the correct password because I just backed it up yesterday. Had the same problem with another backup so I deleted it and backed it up again to the same result.
iPhone X, iOS 12

You can’t restore an encrypted backup without its password. With iOS 11 or later, you can make a new encrypted backup of your device by resetting the password. Here’s what to do:
- On your iOS device, go to Settings > General > Reset.
- Tap Reset All Settings and enter your iOS passcode.
- Follow the steps to reset your settings. This won't affect your user data or passwords, but it will reset settings like display brightness, Home screen layout, and wallpaper. It also removes your encrypted backup password.
- Connect your device to iTunes again and create a new encrypted backup.
You won't be able to use previous encrypted backups, but you can back up your current data using iTunes and setting a new backup password.
If you have a device with iOS 10 or earlier, you can't reset the password. In this case, try the following:
- If someone else set up your device, ask them for the password.
- Use an iCloud backup instead of iTunes. If you don't have an iCloud backup, you can make one.
- Try using an older iTunes backup.
