WebSpeed Login page

It depends on how far you would like to go.

You can make an simple login page with a form asking for a username and password on it.

As a user of your application can put any page in the Favorites of the browser, you should keep in mind to check on every page in your application if the user is logged in. But you could also try to make an application design where al pages are generated through one "frontend" page.

Please tell some more what your plans are.
