forgot encryption password in the iTune backup

This is the article that you are referring to ➡️ About encrypted backups on your iPhone.

The section that you are referring to is below:

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

You can’t restore an encrypted backup without its password. With iOS 11 or later or iPadOS, you can make a new encrypted backup of your device by resetting the password.

1. On your device, go to Settings > General > Transfer or Reset [Device] > Reset.
2. Tap Reset Network Settings and enter your device passcode.
3. 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.
4. Connect your device to the Finder or iTunes again and create a new encrypted backup using the steps above.

You won't be able to use previous encrypted backups, but you can use the Finder or iTunes to back up your current data and set 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. If you don't have an iCloud backup, you can make one.
• Try using an older iTunes backup.

As you can see in the article, you can reset the password, however, you have to create a new encrypted backup file for that new password. The old backup will only open with the old password.

You are not going to be able to use that encrypted backup file to restore from without the original password that was set. You are allowed unlimited tires to guess the password.

Which Apple Help Team gave you the instructions to reset the password? The password to this backup file cannot be reset. You just have to know or remember the password.

But you are saying that these instructions still did not allow you to remove/reset the encrypted backup password ... correct?

Also, as I read them, this will not help you access your previous encrypted backup, but allow you to create new ones with the new password. If so then, what we have provided still stands.

AFAIK, if you can't remember the encrypted-backup password, there is no way to recover this backup. Not sure what Apple told you to try otherwise.
