Hi Bess,

I'm not sure how long the queue is right now, but we're coming back from a
vacation weekend here in San Francisco and it'll probably take a bit for us
to work through the queue this week.  That said, we'll work through it as
quickly as we (securely) can. Each request must be researched before
approval can be granted due to all the concerns with logins and passwords
illustrated in this great discussion thread.

The oAuth page was changed some months back for the iPhone and it
looks quite nice to be honest, it is most definitely the right height
and width for Webkit on the iPhone now, so I'm not sure what the
library you are using is doing.

I still disagree with the above.  oAuth in UIWebView can be spoofed
yes, but at least it shows the user it's a Twitter page, whereas xAuth
still has a username and password field.

I'm not convinced yet that xAuth is right for an app that has a decent
mobile browser or framework.

The library can call a UIWebView inside the app instead of redirecting
to Safari and then looking for the oauth call back and grabbing the
relevant information and storing it.

Exactly how long does it take to apply and get approved on xAuth?

If I apply xAuth today, am I standing on a queue that is 1,000 long?

I am preparing a Twitter Developer Book. If it takes a few weeks and
few months, I would have to change plan not to count on xAuth. Would
anyone give any feedback?

I also like to confirm that I have tested Objective-C OAuth library on
iPhone. OAuth does take you outside the app to Safari for Twitter
authentication page. I test the work flow at Twitter Annotation
Hackfest this weekend. The Twitter authentication page is not
optimized for iPhone. It is difficult for users to find the section
where user can enter username and password. IMHO I would like to see
at least that page is styled and sized properly for mobile browser
webkit so it looks like part of native app with less word in larger
font size and bigger buttons.

The only way you can customize and style Twitter username/pwd page
would be using xAuth.

Indeed a standalone app can fool the user. So can a well designed web
page, it is not that hard. Fooling users is big business these days.
Web services are an excellent tool to do that. Hey, even many
legitimate web services make good money by getting users to pay for
completely useless products and services.

>...  One of the primary reasons oAuth was developed was to ensure

Yes that is a key point. This point makes a lot of sense for a web
based service that acts together with twitter to do something on the
user's behalf. The main risk for the user here are malicious web
services.

My point in saying a webview in the application is that it is more
secure than using a browser *from the point of view of the
application*. 

Inside of my application I can forward a URL to the
system default browser, or I can handle it myself. When forced to to
oauth, I have to do one or the other. Since I have zero information on
what the user has installed as their default browser, I have to assume
it is not secure. 

Aside from that, hopping to the browser and back is a
really ugly solution. 

As I said before, a lot of this stuff is inherently insecure for
reasons completely unrelated to oauth or xauth.

In any case Jann, you have convinced me of something I strongly
suspected - I really should get xauth for my application as well.

Be safe,

Bernd

Re: [twitter-dev] Re: How long does it take to get approved with xAuth?

2010-05-31 Thread Jann Gobble
Okay, I think we really need to expand on something...

oAuth was never designed to promote any app developer to bypass the built-in 
web browser (from an App) -- (ie: using UIWebView).  There are many reasons for 
this.  If one wanted to steal usernames and passwords, it is VERY easy to 
simulate the look and feel of Twitter's login page for oAuth in order to take 
the username and password of the person logging in.  Indeed, there is nothing 
to stop anyone from doing this (directing the user toward their own website), 
getting the username and password and -- in the background -- logging the user 
into Twitter using oAuth, getting the token and proceeding as normal in their 
app.  Later (in this scenario) they could do something insidious with the 
username/password combo.)  Thus oAuth -- used in this manner (in a UIWebView) 
bypasses one major reason oAuth was developed.   In other words, using the 
UIWebview is insecure 'cos the user does not have the built-in notifications 
(some would say guarantees -- although I don't see them as guarantees) that a 
built-in web browser offers.  That is, the UIWebView does not necessarily show 
the URL line with the REAL url that the user is being referred to.  I can 
easily put a UITextField at the top of any UIWebView, put the Twitter URL in 
that and displaying a lock symbol somewhere on my UIWebView.  This "looks" like 
the user is going to the right place but indeed I may be doing a 
man-in-the-midle type attack.

The only security offered by oAuth used in this method is that you are 
exchanging a token once for each function you are asking Twitter to do.  One of 
the primary reasons oAuth was developed was to ensure that the app/website 
NEVER got access to the user's password.  The other was that the 
username/password was passed in the URL, thus being logged in many companies 
firewalls, filters and sniffers -- not to mention Twitter's own access_logs 
(not known -- assumed).

Here is my main gripe:  As someone earlier stated:  The only danger with 
Twitter's password being captured by the app is that you can post as this user 
to Twitter and associated sites.  The main worry to me is not that someone can 
post as me (to Twitter) -- it is that people like my parent may use the same 
username/password combo on Twitter that they do on their banking website.  BUT 
you cannot save people from their own stupidity.

The time for discussing oAuth vs xAuth is over.  Twitter has decided -- and in 
my opinion they have offered us a valid alternative to oAuth for Apps.  xAuth 
is here, it is a valid compromise for the UX in Apps and is not allowed for Web 
Apps.  

That is good enough for me.

I consider it completely the opposite and that the oauth workflow is
more secure than the xauth one. To me seeing the Twitter website login
page shows me that only Twitter will see my login information and not
the client app itself

An xauth workflow the app should only pass it on in exchange for an
oauth token but there is nothing to stop them harvesting the
information in the meantime

Running the oauth workflow on the iPhone is not painful and can all be
done seamlessly from within your app itself. The user won't ben

Twitter has been great responding to XAuth application requests, and
helping developers implement their API.  I suspect with all the OAuth

Thanks!

For now I have implemented xAuth (even though it does not work) by using 
examples and what I expect.  BUT I have hidden the Twitter button on my app 
until xAuth is approved and I can fully test.  

The one thing Twitter does NOT need right now is app developers leaving them in 
the dust because they make it too hard to implement their protocols.  We will 
see how my user base handles *not* having Twitter along side the other social 
networks in my app (until I get approved).  My guess is that they will choose 
to post to their FB Wall instead.  

We will see.

XAuth is is the right choice for an end-user client app and
satisfactorily resolves the UX issues in client applications that
OAuth creates.  Unfortunately, many web-app developers simply don't
know enough about end-user client app development to understand these
UX issues, or why end-user client application trust is neither an
issue that needs addressing nor one that OAuth can (nor even attempts
to) address.

It shouldn't take more than a week or two to get your authorization
from Twitter to use XAuth if you're applying for a client app.

Is it easy for most users? The authentication token doesn't expire, so
an application (any application, not just desktop/mobile client) can do
what it wants for quite a while.

You should be careful with trusting browsers, mobile or otherwise. They
are very leaky.

And my point remains, when using a browser *and* a standalone client,
the user trusts both of them. From the point of view of the honest
application developer, I do not want to assume that another application
(the browser) which is completely unknown to me, is trustworthy. Hence
I prefer the solution with the small integrated webview in my
application.

But also, what do people to with their twitter account that needs
protecting, other than posting messages and media content? And of
course giving away great data to the data miners.

A lot of this authentication business misses the easiest intrusion
vector anyway. People will steal your phone, and have access to
everything you store on it. Including any authentication for serious
business. Nevermind trusting the standalone app or the browser, the
entire system is easily compromised if its stolen.

Trust is not a boolean value. There are levels of it. I trust my mobile
browser to not take over my Twitter account but I only trust random new
Twitter client to not post spam. If the Twitter client breaks my trust it is
easy to revoke access to it.

The user does trust the app, otherwise they would not be using it. The
problem with the scheme of using the app *and* a browser is that the
user has to trust *both* of them. 

And if they don't trust the app, why are they using it to post their
tweets?

It looks like the folks who designed this scheme were not thinking
about desktop/mobile apps, only about web based solutions. The rest is
an afterthought.

Be Safe,

It is NOT secure.  This is my problem with oAuth.  The work-arounds cause a 
false sense of security.  oAuth was NEVER supposed to be used this way.  If the 
user does not trust the app, they should definitely not trust the developer 
that puts a UIWebView in it -- it is too easy to do a man-in-the-middle.  oAuth 
fits in well with webapps, not iPhone apps.

Anyway, this was all hashed out internally to Twitter -- that is why they came 
up with xAuth.

I do the equivalent in Qt. It looks decent, and the user has the
impression that they are typing their password into the app. In fact
they are. 

So the user experience is pretty close to basic auth. I doubt that the
users who have been happily giving away their password left and right
really care who stores their password. Perhaps that situation will
improve with better user education.

An approach with a webview integrated into the app is more secure than
using an external browser - my app doesn't know what browser the user
has configured. Why would I assume that some unknown browser is secure
and doesn't grab their password? Many browsers have nice features for
exactly that. 

There are other glaring holes in the entire setup. Users get an email
PIN from places like twitpic, and once a black hat has that, they can
impersonate the user with embarassing pictures and tweets all day.

So I would advise users to not use any of the twitter environment and
surroundings for banking transactions. And if embarrassing pics
surface, at least users have plausible deniability.


Be safe,

Bernd

You don't have to go from app to browser, embed a UIWebView and then
in

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:
(NSURLRequest *)request navigationType:
(UIWebViewNavigationType)navigationType {

Look for your callback URL and read the query string and you'll be
authorised, then just remove the UIWebView and use your application.
The user never has to leave your app.

Then the user gets MORE security that xAuth because they can see they
are logging in on Twitter.com and not giving their password to an
arbitrary application, which could still save their password without
their knowledge.

The requirement for users to go from app to browser to app is untenable for 
many of my users.  It is a major change to go from app to Safari and back to 
app.  Many users actually think that it the app is less secure (rightly or 
wrongly) because they have to exit it -- and go to the web -- in order to login.

Indeed, many of them do not understand the permissions that the oAuth system 
asks for when they get sent to the Twitter page.  Unfortunately with a phone 
like the iPhone you are dealing with many many users who are new to mobile 
devices in general and just wish to use twitter from within their favorite apps 
without the complications.  

Would you say that oAuth is good enough for Twitterific or Chirpie, Tweetie? 
Well, they are using xAuth.  All I wish to do is to provide my users with 
identical (and what they see is easy -- and safe) method of using Twitter.  
xAuth provides this.  oAuth does not.  Many users prefer a seamless experience 
to that of adopting a protocol that causes such a jarring user experience -- 
regardless of the perceived safety of oAuth over xAuth.  Safety of one over the 
other comes down to how much you trust the app.  It no longer comes down to how 
much you trust Basic Auth.

I would have no problem if there was an even playing field where we could all 
have our app "signatures" in the Tweet -- and all have the same user experience 
where logins and permissions are concerned.  This is not the case.

Thanks for your input, though.
