 <p>This is a very basic management page.  Please excuse the number of alert/prompts that will come up when you click on things as it was the quickest way to build it out.</p>
 <p>Please note: anything modifying data will require you to enter your PIN again as both the web view you are looking at and server behind it are completely stateless for simplicity.</p>
