How can I make a Facebook app that doesn't require users to log in/authorize my app? Is it even possible for canvas apps?
The conversion in auth dialog is quite poor (39%) for my app, even though I ask for the basic information only. Hence the question.
Thanks for advice!

There are no special actions necessary to run a canvas app in Facebook without authentication. Simply set the Canvas URL and Secure Canvas URL in your app's settings (https://developers.facebook.com/apps/<app_id>/summary) and it should just work.
Keep in mind that you cannot access any of the useful functionality Facebook offers if you forego authentication. You'll be missing out on:
- The Invite Friends dialog
- Creating notifications
- Retrieving a user's friend list and information
- Etc.
In fact, if you're not leveraging any of the available functionality Facebook provides, there's no sense in even creating a canvas app. You might as well enjoy the benefits of using the entire window for your application and host it standalone.

It all depends upon what you're doing with your app.
If you app uses features that requires login, then yes, you will need to get each user to log in.
If your app doesn't use features of the API that require login, then don't use it.
There's many social plugins that can accomplish a lot of what many people look for and most all of them don't require a login.
