Tips to remember it here:

If the backup you're trying to restore from is encrypted, you will not be able to use that backup if you can't remember the encrypted backup passcode.

If on a Mac, & you elected to save the passcode to your Keychain, you can recover the passcode from your Keychain. Otherwise, your backup data is unrecoverable.

While you can continue to sync/backup, if you can't remember it & want to remove it, you'll have to delete your existing backups, & restore your phone as a new device. Your data will be unrecoverable.

You delete your existing backups here: iTunes>Preferences>Devices.

No. Otherwise, what use would it be putting a password on it?

Won't help. The ONLY solution, if you can't remember it, is to delete ALL of your existing backups, & then restore your phone as a NEW device.

Your data is unrecoverable.

The encrypted password used for back-ups worked for me. I had to find it in keychain (iPhone Backup; Kind: application password).

Thanks wj!
