We explain here how to reset the backup password of your encrypted iPhone backup..
If you have forgotten the password for an encrypted backup of your iPhone, you can no longer use this backup to restore with iTunes. In these instructions we will show you how you can still get your password and how you can reset the backup settings in order to then create a new backup.
Before you reset the password, you should double-check that it has not been saved in a password manager . If you use a Mac, it might also be worth looking for the password in your keyring :
If you can't find the iPhone backup password, you can only create a new backup. To do this, reset the internal backup settings on iPhones or iPads with iOS 11 or later by resetting the settings of your iPhone or iPad to the factory settings. This means that, among other things, the arrangement of the apps on your home screen, created alarm clocks or customized notification options are reset. However, passwords saved in iCloud and all data from apps are retained. After that, you will still not be able to access the old backup, but you can at least create a new backup. The old backup remains on your computer for the time being, even if you can no longer use it without a password.
