Secure a remote access with IP address

Question

I want to prevent people to access my website outside my home and my father's home. Is it a good idea to check the IP of the connection and to grant the access or is it easily breachable ?

Answer 1

As Jon Egerton already said, your method will work only if IP from your and your father homes are static.

Two other methods for checking allowed connections comes to my mind.

A Login Page requesting for username & password. The example assume you can use php.

Allow only clients with a Certificate installed. The example assume you're using and you can alter configuration of an Apache webserver.
