I just backed up my old iPhone for the first time. I did not realize that the backup would be encrypted, and was never prompted to set a password. I now want to set up my new iPhone using the computer backup (because none of my data or apps would transfer over in the Quickstart transfer). However, I now and being prompted for a password for the encrypted backup – which I don't know because I never set one (and it apparently is not my Apple ID password or my phone password).Is there a way to start over, and create a backup that is not encrypted, or is there a way to otherwise recover a password that I didn't set?
