This is a representative problem below about syncing iPhone with iTunes after passcode
forgot.
iTunes won’t let me
sync my iPhone without entering that passcode, but I’ve forgotten my passcode.
How can I get access to my iPhone and then sync to my phone with iTunes?
We know that when passcode is available, we could easily
type passcode and sync iPhone with iTunes on computer. However, if passcode
forgot, how can we sync iPhone to iTunes to make a backup in case of need? According
to situation you face, select one of the following options to do.
Option 1: Restore iPhone with iTunes and Sync iPhone to iTunes again
Syncing locked iPhone with iTunes seems more difficult for people to do. But you may be able to
reset the passcode by restoring the locked iPhone.
1. Connect the device to the computer with which you
normally sync and open iTunes.
Note: If iTunes prompts you to enter the passcode, try
another computer that you have synced with. Otherwise, go to "If you have
never synced your device with iTunes", below.
2. Right-click the device in the left column and select
Back up.
3. When the backup is complete, select
Restore.
4. When finished, restore from your most recent backup.
If that doesn’t work, you will need to perform a factory restore to remove it. But you should consider whether you have backup for restoring iPhone data after factory reset.
The best scenario is that you have ever backed up your
iPhone with iTunes every time it is connected to computer. So forming a habit
of backing up iOS device at any time can prevent iOS data loss.

Setup Assistant on your iPhone to restore the most recent backup.
