title: Signing iOS application when publishing an update to an existing app on the app store
body: <p>I'm a mobile developer and I'm trying to update a App which is already exist on the App store. My company CTO added me as admin on Appstore iTunes connect. I'm very confused of all the details regarding certificates &amp; provisioning profiles. So my question is: Do I have to create a new certificate and/or new provisioning profile associated with my apple ID? Can't I use the already existing distribution provisioning profile?
  So can someone specify what do I need in order to successfully sign &amp; archive my iOS application.</p>
