Get Consumer oauthtocken and oauthtockensecret for clients


I am working on an application to post tweets for employees and trying to make the process simple for them.

I have an app. registered with Twitter.

Ideally, I’d like to just attempt to connect to their account, then the next time the employee logs into twitter, they approve my app and see the PIN number, which they copy/paste and send to me, and later I enter in my software to get their oauthtocken and oauthtockensecret, which will be encrypted and saved for later recall as needed.

Can someone give me guidance as to how to trigger the application permission on Twitter? Can it be done as above? Do I need their password and just give permission to my app. myself? I’d rather not do that, if I can.

Thanks in advance!
