Is there anyway I can remove my passcode from my computer?

The left side of my screen will not work on my iPhone 6 because of damage. My phone has been restarted but I still cannot unlock it because I need to enter my passcode manually. Of course, part of my passcode is on the left side. I cannot access Siri to unlock my phone, I've been looking up ways. I want to back my phone up but cannot since my phone is still locked. Are there any suggestions or am I screwed?
