Re factoring of code

Question

I was wondering if anyone could help.

 

I'm currently re factoring some code and wondering what is the best way to go about it. I currently have one class file which performs a number of actions and need authentication to do so.

 

What I want to do is only authenticate once across both classes

 

public class Authentication

 

public class Class1

 

public class  Class2

 

I was thinking of using Authentication as a base class so

 

public class Class1 : Authentication

 

public class  Class2 : Authentication

 

If I do the above, both classes will authenticate.

 

Is there away I would only have to authenticate once across both objects, and if I need to re authenticate do the same?
