There are 2 ways to approach your problem.

1. Un-protect your wifi connection by removing the password. This is risky since other wifi gadgets can readily connect to your network.
2. Configure your Samsung phone to connect to your password-protected wifi. Make sure that the wifi protocol of your phone matches that of your wifi router. Example, make sure to set WPA or WPA2 on both device.
   

You will be asked for a password only if you are connecting to a password protected WiFi network.You can set a password for your Home WiFi modem and after that you have to enter the password whenever you try to connect.
