Is there a way I can delete all my encrypted iPhone backups for which I forgot the password, so that I can start backing up from fresh?
At the moment I'm stuck in this loop (below) which I can't seem to exit
To delete the backups, go to iTunes>Preferences>Devices. All iPhone backups will be listed here. Highlight them, then hit Delete.
But if you're using a Mac, I would first try to see if you can find the password in your Keychain (from discussions.apple.com):
Change your iPhone backup settings and start backing up to iCloud instead. You can do that either via iTunes on your Mac or if the password window is preventing you from doing so do it from your iPhone by navigating to Settings > iCloud > Storage & Backup > iCloud Backup ON.
The next time you connect your iPhone to iTunes, the iTunes backups should be gone along with the message asking for your password.
Once you effectuate a full iOS backup to the iCloud, you can revert back to making backups with iTunes instead.
