Q: Im trying to restore my 5s backup onto my SE. It keeps asking for a passwork.  It does not accept my current one.

While your phone is connected to your Mac or PC, and iTunes is open, scroll down to the "Back Up" section of the summary screen and check the "Encrypt iPhone backup" option. You should be prompted with a request to provide a password for the backup. At that point, provide a new password and when you attempt to restore from that backup, the password being requested should be the one you inputed earlier.

Best of luck

If you don't remember the Restrictions Passcode you will need to Restore your device as New.
