You mean the demand for proof of vaccination? That's a city thing.

The passport apps are issued by the states. You download the app and it pulls your state vaccination records. Also, everyone has a vaccination card they got at the time of their first shot that was filled in and signed by the healthcare workers as they administered the first and second shots. Most of the apps are different, but some states use the same platform. Mine is called "Docket". There's also "Excelsior" and "NYC Covid Safe". Mine was very easy to set up, just download the app, enter your phone number and date of birth and that's it.
