I've managed to get a Access Token that doesn't expire, however I've noticed that Data Expiry does have about a 3-month expiry lifespan on it.
From reading Facebook's own documentation, it appears that the access is based on when the user is last active.
Facebook Login also enables you to ask for permissions when people log in to your app. These permissions, if granted by the user, give your app access to items of user data. For example, your app can access a user's name and profile photo.
If an app asks for permissions, it is often necessary to put the app through app review so that Facebook can make sure that data is not misused. Your app can ask for people's name and photo (the default profile fields) and for email without going through app review, but all other permissions require review. For lists of permissions and which ones require app review, see Permissions Reference.
Does this mean that as long as I log into my Facebook profile that's linked - my Data Access will be extended? `
It's not related to logging in to your FB profile, but logging in to your app.
It looks like the token gets extended if it's being consistently used.

I have a livestreaming (consumer) app with an associated Facebook page, and my goal is to broadcast streams from my app onto my Facebook page (live).
I have understood that part of the process to do this is getting a page access token from an admin of the page (like myself), who has granted my app the pages_read_engagement and pages_manage_posts permissions (which I have not done). However, in order to request those permissions, it seems like I would have to change the status of my app in Facebook (from being a consumer app), add those permissions, and undergo app review, even though I only want to request those permissions from a specific user. (This particular method is also not possible, since I already have 200,000+ users actively using my app.)
So my question is, how can I get a Facebook page access token for only a specific user of a specific page?
I am creating an app that only a specific list of users will use, and I need Instagram Public Content Access permission (and some other permissions) for them (I have my Instagram Business Account all set up and connected with Facebook page).
On https://developers.facebook.com/docs/facebook-login/review/examples/#screencast there is stated:
You do not need to submit your app if it will only be used by you or
by a reduced number of people. Any account listed in the Roles tab in
your App Dashboard, such as admins, developers and testers, can access
all permissions and generate a user or page access token.
So I just want to make sure, that it is completely fine in my case to keep my app in development mode and let my users use it like this (so I don't need to submit my app for review as long as all the users are going to have their role assigned in my app), and that these permissions are not intended just for a limited time period or only for testing/development purposes.
Thank you for any answer.
What you quoted there, is applicable to permissions your app is going to ask its users to grant to it.
Instagram Public Content Access is not a permission, it is a feature. You need to get it reviewed, if you want your app to be able to access content that the users of your app do not have admin access to.

Am I allowed to create an app that only invited people can join?
Or do all apps have to be open to everyone?
You can have a white list for people who are allowed to use your app in your database and ignore any request for other people.
EDIT:
As per the question in the comment section, I will give you more details. I have not quite done exactly this, but I can guarantee you this is possible. I have a website, linked to Facebook and people can log in to the site using Facebook. In my database I am storing the Facebook ID and the Facebook user access token. When a user clicks on the login with Facebook, his Facebook user access token is checked against the database. If the Facebook user access token (which works like a temporary password) expires, it is renewed. However, people are identified by their Facebook ID. I could easily have a white list for Facebook IDs and allow access only for people whose Facebook ID can be found in the database. My project strategy is to get as many users as possible, but I could easily modify this to restrict access for not verified people. Your problem with consistent login probably lies in the fact that the Facebook user access token expires in a few hours. However, that problem is solvable:
if the user has modified his Facebook password, or has not connected to the app, then he will be asked by Facebook for permissions
if the user is no longer logged in, then he will have to log in
if the user's Facebook user access token has expired, then you should generate a new Facebook user access token
finally, you can generate long-term Facebook user access tokens, which last for months.
Read the documentation for details, but keep in mind that things might have been changed at Facebook since the documentation was written, therefore you should not believe everything written there, but should rather test the validity of the most important statements.
I have a desktop app which uses a user access token to read the me/feed endpoint and I can see all the posts for the logged in user. If I wanted to simplify deployment to different users I would need to minimise the amount of setup/configuration they did.
Is there a way to access me/feed for a given userid rather than have to setup every user as a developer account and create an app for it?
I have looked at https://developers.facebook.com/docs/graph-api/using-graph-api/v2.0 and it is not obvious to me how to do this.
What configuration / permissions does the user in question need to do to activate this. Which access token should I be using, and will it give access to all the posts in the same way the user access token does.
[EDIT] I have looked at this again and the problem I am having is that when a user (who has a facebook account but is NOT a developer) tries to login to my App (which is in development mode) I get the following error
"App Not Setup: The developers of this app have not set up this app properly for Facebook Login."
Thanks in advance
I have an app, and I can write to user's walls with it, having requested the publish_stream permission when they sign in.
I've also created a page and a group, and would like my app to be able to write to those. (Specifically, I want my back-end server to post some updates to those periodically, without a user being involved.) The ability to do this seems to be implied by the descriptions of the /feed parts of those here https://developers.facebook.com/docs/reference/api/page/ and here https://developers.facebook.com/docs/reference/api/group/ . However, I can't seem to find a way to authorize the app to write to these pages. Those docs say it can be done if you have publish_streams and manage_pages. OK, but how do I grant those to my app?
In the user case, you request those permissions when the user signs in via the OAuth flow. However, the page and the group never sign-in, so there's no way for them to grant the app permission. I looked around the settings pages for the group and the page, and couldn't find anything that will let me add the app. So how do I give the app the required permissions to post to the group and the page?
Found it!

"Application Page Access Tokens
To perform the following operations as an Application Page, and not the current user, you must use the Application's Page access token, not the user access token commonly used for modifying Graph API objects nor the Application access token. This access token can be retrieved by issuing an HTTP GET to /USER_ID/accounts with the manage_pages permission. This will return a list of Pages (including Application profile pages) to which the user has administrative access, along with an access_token for each Page.
Note: Applications that are configured as Native/Desktop apps will not be able to make API calls that require an application access_token."
So:
I went to http://developers.facebook.com/tools/explorer/ and, as me, created an access token with "manage_pages" permission.
I then went to https://graph.facebook.com/$myname/accounts?access_token=$accesstoken
and it gave me a list pages and apps that I had given permission to. I copied the access_token from the relevant page, and pasted that into my code, so that the server-side create event code always used that access token.
And it worked!
