Can test users be verified? Can they have usernames? - facebook

I'm working on an app where I'd like to be able to do things with a user's Facebook username. I know that I can get this through the basic user object, but I'm worried about the case where the user doesn't have a FB username when they register with my site/application, but does gets one later. The question is how to test this with FB test users:
A user (a regular user, anyway) has to be verified before they can get a username. Is it possible to verify test users?
If so, is it then possible to give a test user a username?
Is it possible to change that username as part of the testing process (on the chance that my code doesn't work perfectly the first time :)?
What I'm thinking of doing is setting up a realtime subscription on "username", which I've established is possible. If the user above suddenly gets a username, my app gets notified and I can do whatever I do with it. But that implies that a lot of other things are possible, which they may not be. I could retrieve and check the user object on login and keep updating the fields, but I'd prefer to avoid that if possible. Any advice out there?

You cannot claim usernames for test users. You will have to use your own account or test with a real fake account, which Facebook frowns upon.

How to get email and username when Facebook registers

As far as I know, on the new Facebook API, there is no way to get the Facebook username. Also, if the user registered to Facebook, his or her account might lack an email address if he or she logged in with a phone number.
However, I am working on a project, where, upon login with Facebook, if the user does not have a user, then the Facebook login is interpreted as a registration. Since, according to my best knowledge, there is no way to get the Facebook username using the API, I am using the email field to generate a username, taking into account only letters.
However, in some cases, the username generated this way is duplicated, or the Facebook account does not have an email address. The best solution I can think about is to redirect the user to a form where he or she can enter the email and/or the username, but that would not help the user-experience.
Is there a way to gather these data without making the user enter them? Or something close to it?
First of all, you should always present the data you want to store to the user BEFORE you store it, and let him change it.
That being said, the (App Scoped) ID is the only thing that is really unique, you can either use the email directly (if the user is already registered, just add the Facebook ID to your database) and present an input field if there is no email - or generate a username with his first and last name. Present the chosen username to the user and let him change it, or tell him that it already exists.
After all, wouldn´t a user WANT to choose his username?
If you want to make it smooth for the user and don´t want to bug him in anyway, you can just store his Facebook ID. Or just use the email directly as username (including the # sign and the domain), as i wrote above. If that´s not good enough, you need to implement your own routine to auto-generate usernames. There´s no general logic from Facebook to do this.

Password/Authentication for users inside App on iOS

my goal is to give my customers an option to lock their App's Data, so when they give their iPad/iPhone to someone else for an extended period of time, users can't access or accidentally look at confidential data.
[Some Background: It's a medical Application where physicians/staff-members would give iPads to patients. Now the patients are supposed to access some contents, yet shouldn't be able to look at other patients data]
So far, I have a password inside my App. But when a staff-member forgets and wants to reset it, the only thing I can do is "deletion of the whole database". I have a Disclaimer telling people to store their password somewhere, but this is still not the optimal user experience.
Is there anyway I could authenticate the user via his Apple-Password? This way only the person knowing the Devices-Account password can access the data and can always reset the Apple-Password with Apple.
PS: Server-Solutions, like having a User-Password pair with reset-via-mail on a server of mine is out of the question, since it would add to much complexity for the users and in many medical situations the Device shouldn't have access to the web.
Multiple thoughts:
I am not aware of any native public API to authentication using Apple password.
If your app is enterprise app, possibly you can use native private API. I would recommend to disassemble AppStore and check how does it do authentication then
You can also to try to access to some Apple web page which requires authentication and pass to it apple account and password and see what it will return. If it authenticated correctly, then you are fine and you can reset a password.
To make it secure, you will need to ask a user to enter it for a first time, so you can encrypt your encryption keys using authentication material (so you can decrypt encryption key later on).
However, I am not very big fan of this solution, since you can change Apple password and you will be stuck in such case.
Server solution is the best option and it's not that complex. Another option is Forgot password. You ask something what administrator know ("What is your first pet?") and he enters the answer when your application is configured and this answer could be used later to unlock your app.
P.S. And the best solution at the end (which is absolutely shameless self advertisement). A startup which I am part of (SpydrSafe) works on the product which solves exactly your problem. In fact, healthcare is one of the verticals which whom we actively works. If you are interested, contact me (my email is in profile)
if you authenticate the user via apple password, and they forget their apple password, then in order for them to retrieve that password is by reset-via-email .... so either way you are stuck with that dilemma.
As for actually using your apple password, no.
Best way to get what you want is to have the password stored somewhere in real life. Like another computer that the doctors can report to and ask for passwords or just don't forget the password.

Facebook test users and auth

I have a project where I am using Selenium to test the Facebook auth. I created a Facebook app, created a test user inside this app and created some tests using Facebook login. Until now, it was working. But during the last two weeks something changed in Facebook and my tests are failing. It is due to interface changes in permissions dialog (I am targeting the button by his id). The second problem is that I don't get the email address from Facebook test user but a proxy email which is longer than 75 characters (my db field length is hardcoded in framework I am using).
If I log in as a regular user, it is working correctly and I get this permission box:
But when I log in as the test user I created (via 'switch to' in app's developer roles), I get this box:
I tested it ~2 weeks ago and this was yet working. Today it is changed. So my questions:
How to get back the old permissions box for test users?
How can I get the real email address and not the proxy?
Thanks!
I experienced the same problem with the Auth Dialog. I tried it with some old and new apps with various settings including March/Apr. 2013 Breaking Changes enabled/disabled, but it didn't help.
However, I guess I can help you with the email problem. When you login as a test user and go to account settings page, you will see the test user's primary email addres. By default this should be a really long one like the image I attached.
Facebook Platform returns this primary email address. If you pass the Auth Dialog with your test user account and see the privacy setting page, you will find the default primary email address is shared with the app. You have to provide a new email address for the test user and set the new one as primary email address via account setting page.
Why is the Login Dialog different with a test user?
With your test user, you can see the future of login dialogs. In fact, this isn't "not working" but this is an update which was unveiled on December 2012. Let me quote:
Our Login dialogs have undergone a redesign to make it easier to
understand permissions that apps request. We've simplified
presentation and have also updated our language for greater clarity.
“Basic info” has been renamed to “public profile and friend list,” to
reflect what what is being shared. Apps accessing your public profile
get your name, profile picture, age range, gender, language, country
and other public information.
Source: Providing People Greater Clarity and Control, developers.facebook.com/blog
The reason why you don't meet this update with a regular user, is that Facebook doesn't use to update everyone at the same time. They partially launch updates depending on the country, the type of account or some other parameters I ignore.
Example of a partial update (unified_message FQL table) dedicated to developer accounts:
We are providing early access to this API for registered developer
accounts only until the new messaging system is broadly available. You
should use the message table for production applications at the
current time.
In our case, we now know that test users can access to the update, but it is also said:
We have already launched many of these improvements as part of our
iOS6 integration and are now rolling them out more broadly.
About proxy emails
In fact, proxy emails are a way for any users to keep their real email anonymous. You have to consider proxy emails.
When joining an app, the user can choose between a real email and a proxy email:
Other thing you need to expect are users who didn't validate their account when connecting to your app, a case which is possible as described here and here.
Then, why do test users give back a proxy email? Because test users (being bots and having fake emails) didn't validate their emails.
You see that in at least 3 cases (and finally, test users are a good example), you need to handle these proxy emails. They are incidentally or accidentally met by developers and they can't be neglected. For your case, you can still try to disallow tests users who have a proxy email from accessing your app. But you should accept them and shouldn't force them to share their original e-mail addresses. A better solution is that you validate the test users emails:
Connect to the test user account that gives a proxy email
Add an email address (password needed here),
Go to the email mailbox and click on the validation link,
Set the new email address as primary,
The test user should now give his original email and not a proxy anymore!

Do we need client-side flow or server-side flow or both to implement the login with facebook feature?

Currently on my website, users login with their login id and password, they are also required to enter their email when they register. Both login_id and email column on the users table have unique index. users table also stores other data associated with the user such as gender,last_name,first_name but these are optional (nullable) fields.
There are two changes I would like to make to the website.
The first one is, users can use their email (in addition to login_id) to login. For new users, when they register, they no longer need to provide a login_id because they will be using their email to login.
The second change is, they can login with facebook. For new users, if they login with facebook for the first time, their facebook uid will be obtained and stored in my database. This means I will have to add a facebook_uid column on the users table.
For existing users, when they login with facebook for the first time, I should first obtain their email address from their facebook profile and then check if there already exists a record using that email in the users table, if yes, their facebook uid will also be stored on the facebook_uid column on that record.
According to facebook, its platform supports two different OAuth 2.0 flows for user login: server-side flow and client-side flow. Which one or both is required for this use case?
Also, what problems can be anticipated when I implement the features like I describe above?
You could take either approach for this, it's entirely up to you. Both methods will give you the data you need, it's a question of how comfortable you are working on the back vs front end. You just need to ask for permission to access to the user's email address.
Problems that could happen: I'm not sure but there may be legal restrictions on storing the user's Facebook ID. Also, what if someone (not me, an evil person!) registers with my email address and you don't validate that they really have access to that address - then when I log in via Facebook, the app will assume we're the same person and the evil hacker now has access to my account. Unlikely scenario but could happen...

Facebook Connect Implementation questions

I hope this is allowed but I have a number of questions regarding Facebook Connect, I'm quite unsure on how I should approach implementing it.
I am working on a live music type service and currently have user registration, etc. If I were to implement Facebook Connect alongside this, would I still be able to email the Facebook Connect users as if they were on my database?
Also, would it instead be possible to let users who have Facebook "link" their accounts once registered so I am able to give them the benefits of sharing via Facebook and inviting friends while still having an actual registered user on my system.
I have tried to read up answers to the above questions but what I've found is quite ambiguous.
Thanks, look forward to your views.
Facebook's documentation process is very poor, so don't feel bad about having a hard time getting started. Their wiki-style approach to documentation without any real official documents tends to leave the "process flow" tough to grasp, and requires piecing together parts of a bunch of randomly scattered docs.
Facebook has an obligation to protect privacy, so they never make a user's actual email address available to application developers, through Connect or normal applications. They do have a proxied email system in place that you can use, however, you must get explicit permission from a user in order to email them. There's a decent document on proxied email here. You can get permission by prompting for it; there's several methods for doing so linked in that document.
In regards to linking Facebook and local accounts, this would definitely be the way to go. Once a Connect user logs in, you want to store that fact for that user so you can provide the Facebook-specific functionality. I would simply create a normal user account in the database for every new Connect user that came by, with it's own local id, so that you don't have to do special handling of two different types of user accounts all over the site. That being said, the account would obviously have to be marked as a Facebook user's account (I use an externalId column in my users table), and any part of the site that relied on information you might otherwise have locally would have to handle the Facebook aspect properly (such as using proxied email instead of normal email).
For existing users, you could arrange an "account link" by having a process whereby they log into FB Connect after they've logged into the site already, and you could detect that and simply add their FB id to your users table. After that, they could log in through Connect in the future, or through your normal process. I've never done this, but it should be possible.
If you write the account handling code generically enough, your site will be able to function well no matter what kind of user you throw at it.
