Is the Mobile Passport app secure?

Yes.

Set up a PIN and/or TouchID to open the app on your device. Your personal data is saved on your mobile device and transmitted securely to U.S. Customs and Border Protection (U.S. CBP) for review, just as if you were using an Automated Passport Control kiosk. The Mobile Passport app does not share your personal data with third parties nor is your personal data saved on a virtual system. If you set up your passport on the app and decide to transmit it securely to U.S. CBP for review, your digital receipt in the form of an encrypted QR code will expire four (4) hours after submission. The Mobile Passport app gives you the option of storing your data on your device or deleting it after your trip. We welcome you to read through our Privacy Policy here.
