To the OP, if you don't have a Samsung phone, then your only option is to do a hardware key factory reset, which will require you to enter your Google account/password (since that will trigger Factory Reset Protection). Hopefully you remember that.
In the future, treat your phone password as if it were the combination to a safe. If you forget the combination, then you have a very heavy paperweight (unless, I suppose, you use a heavy-duty drill or some TNT).
