Authentication

When you create a canvas app, you can use one of the following authentication methods:

• Signed request—The default method of authentication for canvas apps in which the signed request containing the consumer key, access token, and other contextual information is provided to the canvas app.
• OAuth 2.0—Canvas apps can use the OAuth 2.0 protocol to authenticate and acquire access tokens. For more information about OAuth and the Force.com platform, see http://wiki.developerforce.com/page/Digging_Deeper_into_OAuth_2.0_on_Force.com.
