title: Tab Pages (Signed_Request / OAuth 2.0 / SSL)
body: <p>I just wanted to make sure I understand the requirements of the upcoming October 1st deadline!  I know that canvas apps require using OAuth 2.0, I am just wondering if tab pages have to require it?  I am just building a fan gateway page and I'm using the signed_request to check if they like the page already, but I have no need for additional permissions, so is authentication/asking for app permissions even necessary? </p>
