Janole None, taken. I am a network sysadmin, developer and ultimately businessman so I do know a little bit about how they are all related.
I understand you are in a slightly different position having to deal with xAuth. However, xAuth is not a secure system in itself. Any system that passes a user and password through a third party cannot be secure. Yes you are "supposed" to discard the info after the initial tokens are exchanged and received back, but there is no proof that actually happens. A third party still had access to my username and password. >From a purely network and security standpoint xAuth should be done away with >in lieu of newer more secure methods where no one other than myself and the >service I am accessing know my password.

Your work around sounds like it will suffice and is no less potentially insecure than the existing if properly setup. You say you "know nothing" about your users under the current system, and that's the way it should be. But that is you in your specific case, being I'm sure an honest developer. Allowing insecure methods to continue though, lowers the security of the whole. It only takes one bad app to screw a bunch of users and ultimately it's Twitter who would have the proverbial egg on the face. The app developer would be banned and forgotten. I'm not happy about this change being forced down everyone's throat so quickly as much as the next developer. In my option more levels of privacy and security should have been rolled out all at once instead of this one change. This change fixes one minor problem when a more broad change to add finer-grained permissions could have been rolled out and affected third-party developers not much more than this current one. I also suspect as you hinted there may be other more selfish reasons partly behind such changes and have written several articles about the subject. http://bit.ly/lFZuZC But as I said... from a purely network and security standpoint the changes are sound. Economics and competition may be a different story. damonp On Thursday, May 19, 2011 at 11:14 AM, janole wrote: > Damon, > > with all due respect and in all politeness, have you even read what > this thread is about? > > Do you really think an xAuth application - that knows the users full > credentials - is getting more secure without the right to access > direct messages?
