Set up phone forgot password now can't get in my phone

Hello, do you still have access to your google account?

If so, you should be able to manually reset your phone, although you will lose all data stored on it, it will likely ask you to log into the same google account you used previously when you set it up again though. With the phone powered off, you can hold Power and volume up until it gets to the reset menu, where you can use the volume up and down buttons to select "Wipe Data/Factory Reset" which will then ask you to confirm, and then begin resetting your phone. Hope this helps!
