Welcome to Android Central! Try using Samsung's Find My Mobile to remotely change your password: https://findmymobile.samsung.com/. If that doesn't work, then you're probably stuck. You'd have to do a hardware key factory reset (which will obviously wipe your phone), and then enter your Google account name/password in order to proceed (due to Factory Reset Protection): https://support.t-mobile.com/docs/DOC-30227

Passwords are incredibly important on your device. If you're prone to forgetting them, consider writing them down on a piece of paper and keeping them somewhere secure, like a safe.
