This is my code but ı have get errors

char* password = "123"; 

My error is :

C:\Users\Guest_Melik\Documents\Arduino\keypadservo\keypadservo.ino:5:18: warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]
 char* password = "123";
                  ^~~~~

That is a warning, not an error. It is warning you that it may cause problems. If you are never going to change the value of password in the sketch then use

const char * password = "123";

@UKHeliBob

const char * password = "123";
