Download the Moss mobile app for iOS or Android, or scan the QR code to open up the app/play store on your phone.

Login with the same login information you use for the Moss web-app.

After entering your login info, you should get an SMS code to the phone number that you connected with Moss. Take that code and enter it into the app.

You will receive an email with a code. Take the code and enter it into the app.

Now you have to enter a 4 digit passcode which will replace the SMS security code in the future. Enter it twice and make sure to remember the passcode for the future.
