I turned off my phone and then turned it on and my thumb print isn't enough now I can't get on my phone. I have not set up a password yet and it needs one to get on.
If you restart your phone, then you will need to enter your Passcode before you can use TouchID. In order to set up TouchID, you have to set a passcode. If you don't know your passcode, then you will have to restore your device and activate with your AppleID.
You cannot set up Touch ID without setting up a passcode. Since you've forgotten your passcode you'll need to follow these instructions: https://support.apple.com/en-us/HT204306
