You can sign-in to the iPhone TapeTrack app using either a 4 digit Passcode, or your iPhone's Touch-ID sensor (if supported).

In the event you have forgotten your Passcode, you can reset the pin using the Reset PIN button on the Sign-in Settings screen. If you select this option your adapter settings (including credentials) will be erased. Please note that as the adapter data is hosted remotely this will not be erased.

The List screen will display your Libraries and their contents.
