Later that day, Stephen receives a message from someone claiming to be on Team Pullman. He asks to establish a secure messaging connection with Stephen, which Stephen agrees to. The other person turns out to be Tom Duffy, campaign manager of Team Pullman, and he suspiciously suggests that Stephen ought to consider working for Team Pullman instead of Team Morris. Stephen does not like where the conversation is heading, and decides to end the conversation. He also erases any record of the conversation occurring and removes Tom as a contact, to ensure that no trace of the conversation can be found.

Task #1
First, in order to establish a secure connection, Stephan meets with Team Morris and shares his identity. He does this by going to his Contacts panel and clicking share.
This brings up a Stephan's QR code along with his key. Users can manually enter the key or take a picture of the QR code. In this scenario, Stephan prints out the ID page and passes it around to the other members of Team Morris (the lock button is provided in case the user wants to pass around his or her phone).
