The Digital Agency already appears to have begun its analysis.

One major change seems to be the removal of the equity perspective. It also replaces “user” with “customer.”

On June 2025, the Trump administration reversed major parts of the digital ID policies advanced by the previous administration. This effectively abolished measures promoting nationwide use of digital IDs and mobile driver’s licenses. The administration cited “preventing fraudulent receipt of public benefits by illegal immigrants” as its main reason, but the decision sent shock waves through the digital ID industry.
