Digital IDs are a contentious concept primarily because of the concentration of – eventually – the entirety of people's sensitive private information in centralized databases controlled by the government, and on people's phones, "client-side."

That in turn brings up the issues of technical security, but also privacy, and the potential for dystopian-style mass surveillance.

Proponents, on the other hand, like to focus on the "convenience" that such a shift from physical to digital personal documents is promised to bring.

In the US, some states have started this process via digital driver's licenses, and the executive order is urging ("strongly encouraging") both federal and state authorities to accelerate this, as well as other types of digital ID.
