If you do not have a password for your iPhone, you can not connect it to iTunes. The phone requires code authentication when connecting to a computer.

If the code is forgotten, then you can only do a restore of your iPhone. It will delete everything, and restore it to factory settings.

If you want to do a restore and delete everything, follow this guide:

1. Connect your iPhone to your PC with iTunes

2. Quickly press Volume Up, then quickly press Volume Down, and then hold down the Power Button until your iPhone restarts and starts up in Recovery Mode. Recovery Mode is a black screen, with a computer and cable icon.

On your computer. Now you can select Restore, and wait.
