Say you create a 'config.properties' named file somewhat like this :
userName=admin
password=admin
and say you are using Java as your programming language, then you have to use it in this manner:
Properties properties = new Properties();
properties.load(new FileInputStream("Config.properties"));
String uName = properties.getProperty("userName");
String pwd = properties.getProperty("password");
Now you have got the values fetched from properties file, use it wherever required.
