We're on the verge of a full boycott by users on apps that take passwords.  Comments like this on ChrisBrogan.com keep me up at night. There's a groundswell happening, and it doesn't look pretty. I know Twitter is working on something, I just really hope it's soon.

Aye, aye. I will be making an identical recommendation to my audience tomorrow. Sorry, Twitter. This is getting deadly.

Honestly, most people (rightly or wrongly, i suspect rightly)
don't really worry about it that much. I don't really think a
boycott is likely to be effective.

Also, the chrisbrogan.com post confuses phishing with risk of
giving an evil service your password. They aren't really the same
thing.

For example, oauth type systems are generally considered to
raise the risk of phishing happening (because they involve
jumping the user all over the place to different sites) while at
the same time (if implemented well) they can reduce the impact
of a successful phish (by giving the user and the service more
tools to control usage) They're also substantially more difficult to
implement perfectly, raising the risk of code vulnerabilities.

Lots of tradeoffs well worth discussing (it's certainly a teaching
moment) but the level of run-in-circles-scream-and-shout is getting
to the point of being unhelpful.

I've been lurking on this list for a while. It's a nice resource for
Twitter development. I'm currently working on my own desktop Twitter
app. However I have apparently missed something on this list.

What exactly is wrong with an application (for Mac OS X in this case)
asking for a user's Twitter user name and password. Storing the
password in the OS X Keychain isn't hard at all and it is encrypted.

Have I really missed something important? Does this "fever" about
apps asking for passwords apply to desktop and web apps, or just web
apps? I'd really like to know whether or not my application would
suddenly become "evil" because it asked for an account password. And
yes, my app does inform the user that the password will be stored in
the Keychain and it uses HTTPS when talking to the Twitter servers.

Reply on list or off list, which ever works best for you.

Ed and I were sort of making that argument earlier.

In my opinion (I don't work for twitter or speak for them), I think 3rd
party webapps have the most to gain from going OAuth, and desktop apps
probably have the least. This is why I'm hoping Basic Auth will persist, even
if in a limited or deprecated sense. It's not much good to make a desktop
app walk the OAuth workflow because frankly an evil client application can do
many more usefully evil things than simply being naughty with an OAuth token,
and in some situations might make it impossible for that app to operate in
a useful sense. (Think of all the little Twitter bots that are basically
curl and a shell script, but still do useful monitoring work.)

However, it *is* much more useful to make a 3rd party standalone web app do
it, and that's why Twitter is going to offer it.

If you're storing the password securely and only using HTTPS, I'd say
you're doing right by your users. In the absence of OAuth, that's
basically best practice. It's also a pattern that's been deemed
adequate by companies like Amazon, who collect and store financial
information from their customers.

Christopher St John's comments above accurately reflect my own
concerns. OAuth is not a security magic bullet, and it only encourages
phishing attacks. I feel bad for users that have given their
credentials to a phishing site, and we'll do everything we can to
educate them, but token-based authentication systems are not going to
fix this particular security problem.

Getting worked up into hysterics about boycotts is just, as security
expert Bruce Schenier is fond of saying, "security theater". It's the
equivalent of an apartment building's tenants telling their landlord
they refuse to use keys because someone's place got broken into.

Because your app could be evil[1], and, right now, a Twitter password
is a non-expiring full-access read/write token. And somebody could
tweet something evil while masquerading as you. Of course, you
can always just change your password, but that's inconvenient. And
there's a chance you use the same password for Twitter and
your bank account.

Logically, it's just as risky to give your password to an evil desktop
app as it is to an evil web app (since the desktop app can always
transmit the password to a remote server) However, most of the
discussion has been about web apps.

To be fair, an evil app could just as easily say (and even do)
that.

Cameron, Alex: Thanks for responding. I just wanted to make sure I
hadn't missed some major technical issue. I see that I haven't. I do
agree with Alex in regards to the "security theater" comments he
made. It doesn't appear that OAuth will make things any better, even
if all Twitter apps are required to support it.

Christopher,

I agree with your points. As someone else on the list asked, what is
the solution to this issue? It doesn't really seem to be a technical
issue at all, but rather a trust issue.

Unless I have missed something you need the users password to post an
update to their personal timeline. If the application doesn't ask for
this information then how will their timeline get updated? Perhaps
someone has already provided that answer. I'll dig through the
archives tomorrow.

And with it being a trust issue you can extend that to a multitude of
things in terms of computer applications (desktop and web based).
Actually the real issue is the reputation of the entity that wrote the
application. It all comes down to public relations.

For my own self, or rather for my application, I feel pretty
comfortable asking users to enter their user name and password combo.
Can I prove I won't be doing anything evil with it? Yes, if I release
the source code (which is currently under consideration). If I don't
though then obviously I can't prove I'm not doing bad things with it.

Don't you just love moral dilemmas brought up by technology? :D

Thanks to all three of you for providing answers that were free of
scare mongering.

Dale

Alex, sorry, but this is more than just security - this is getting ready to put a whole lot of businesses out of business, thanks to the lack of such a mechanism.  Regardless of whether it's the solution or not (I still argue it would have helped), if users boycott, our apps don't get used.  If our apps stop getting used, Twitter stops getting used.  There are entire groups of users out there right now asking what apps could be the culprit.  I've heard some mention my app.  I've heard others mention TweetDeck.  I've heard some mention Twhirl.  All these apps, whether they have any chance of being the culprit (I realize they don't, but your users don't have any way of knowing - all these apps collected their passwords), all have the chance of getting cut off of Twitter here real soon by the users if something isn't done.  Didn't you guys say at one point the majority of your traffic comes from the API?  This is more than just not using keys - this is about telling the landlord you won't pay them for the month because they refuse to install locks.

This issue is huge for us as developers, and I don't sense that urgency from Twitter.

I wholeheartedly agree with Jesse. IF users spread misinformation
about 3rd party apps that request passwords ALL being evil then we are
all in the same sinking boat.

Oauth is one part of the solution enabling serivce authentication. It
made me wonder will twitter also add in support for openid for better
user authentication? Better still will twitter offer a "Twitter
Connect" service like Facebook Connect an Google Friend Connect? As a
3rd party developer we could support Twitter Connect to authenticate
the user and then use Oauth for the service(s).

Personally I would like to offer my users the option to authenticate
with their preferred ID service - see http://www.janrain.com/products/rpx
- and then use oauth to request access to their services. The one
thing that prevents me using RPX or creating my own version of the
service is the lack of twitter support for openid.

Scenario: User logins in via Google Friend Connect to our service. I
now have an authenticated user but how do I associate them to their
twitter account? Today I would still need them to give me their
username/password but when/if oauth via twitter existed I could
request authorisation to their twitter account and any other services
they use that supports oauth.

Ah, but what people _should_ refuse to do is give out copies of their
keys to those who are essentially complete strangers just to water their
houseplants or feed their cat while on vacation.

You should only give your key to someone trusted who then acts on behalf
of the stranger to let them in, watch them water the plants or feed the
cat, then ensure they exit your apartment without doing anything else.

Yes, tenants should tell their landlord that having to give out a copy
of their key is not acceptable, especially when the break-ins occured
using a copied key that was handed out.

Still, why do we care? It's just a Twitter account being compromised -
what, do you exchange trade secrets in DMs that you wouldn't want
someone else to read? Hint: Twitter isn't a confidential and secure
messaging transport. Don't try to pretend it is.

You say this like it's a bad thing. If we want to see a solution from
Twitter, there has to be a real business reason for them to fund it.

What better business reason than "our API traffic dropped by 80% in one
month and has remained at that low level for the past three months."

Let the panic continue. Either we'll see a workable solution to the
problem, or folks will just stop using the API - either way, we'll
finally have some clarity on the situation.

Cameron's comment shows why a system like Oauth is important:
Making it easy for third party developpers.
Making it easier for users to build trust.

Btw business idea, as it did work with summize:
Build an oauth service between third apps and twitter,
gain the trust from the users, "force" devs to use it. As
this can be switched on by twitter any moment:
take a small amount of money from the users
in the meantime until twitter implements it.

I'd probably pay 10 dollars a year for such an intermediary
service (so make that 5 for six months)

Business idea 2 for you so you don't canibalise yourself:
Let's use a pledge drive to put up money for you and
implement these.

Alex:
Christopher St John's comments above accurately reflect my own
concerns. OAuth is not a security magic bullet, and it only encourages
phishing attacks. I feel bad for users that have given their
credentials to a phishing site, and we'll do everything we can to

fix this particular security problem.

Of course it is not a magic bullet but let's not forget that having to provide my
login data on third party apps because nothing else exists is really stupid.
It may not be the magic bullet but in comparison that is miles between those
too.
 
Getting worked up into hysterics about boycotts is just, as security
expert Bruce Schenier is fond of saying, "security theater". It's the
equivalent of an apartment building's tenants telling their landlord
they refuse to use keys because someone's place got broken into.

The equivilant you are looking  for is that in order to have operations
done in my appartment all I can do is hand out my keys instead of
being able to use the trusted third party service which will watch
them just for a bit.

Are users stupid and dont know what they do? Of course. Basically
it surprises me to see it took them phishers so long to go for it.

But you can see a clear correlation with some of the recent news
with twitter news popping up on sites like digitalpoint and co.
 
The ecosystem is one of the reasons why Twitter is succeeding,
interviews with users show that over and over again.

Twitblogs-

There is no reason why any Twitter user should simply trust an app because *you* created it. Though I inherently trust you and there's no reason to believe you would create a malicious app, no one can *verify* that. Trust yet verify.

That's all we are asking for. Until there is a verify mechanism, yes, no app at all ever on the planet, including my favorite TweetDeck, should be trusted. Ever.

I think that's what is being said here. And if that hurts business, well... blame Twitter. Or Bush. Or both.

Use an open source application, then. You can verify the source yourself.

But, but, but...  People have been entrusting their email account usernames and passwords to desktop clients and even web clients for years; the same sorts of problems are theoretically possible there and, in the myriad cases of Outlook being attacked by viruses that spam everyone in your address book, quite feasible.  Yet I've never heard anyone suggest "securing" your email program by forcing it in some way to not remember your password, making you type it in every time.  Why this uproar over twitter authentication, when the open problem of mail authentication has been worked around for decades?
