Can we get the Facebook user access token without prompting to login page. Isn't it enough having App Id and App Secret to get the token. I have tried according to the Facebook API documentation. But it prompts to login screen if you are not already logged in in the browser.
This is what document says,
User Access Token – The user token is the most commonly used type of token. This kind of access token is needed any time the app calls an API to read, modify or write a specific person's Facebook data on their behalf. User access tokens are generally obtained via a login dialog and require a person to permit your app to obtain one.
