Denmark Sets June 3 Launch for AltID Digital Identity App

Denmark’s Agency for Digital Government is preparing to make AltID available on June 3, giving eligible users access to an official digital identity app for identification and age proof on their smartphone. The app will be available to anyone over 13 who has a MitID account and a Danish personal identification number, known as a CPR number.

AltID is tied to MitID, the national digital identity system that Danish residents already use to log in to public and private services. In its first version, the app lets eligible users create two proofs: a digital legitimation card that can be used as proof of identity, and a separate age proof that confirms a holder meets an age threshold without disclosing broader identity details.

The age-proof feature is the more pointed of the two for the current policy moment. Rather than handing over a full identity document to prove age, a holder can present a credential that attests only to the relevant fact, an approach aligned with the selective-disclosure and data-minimization principles that European regulators have been pushing in age-assurance debates. The digital legitimation card, meanwhile, gives residents a phone-based way to prove who they are in situations that previously required a physical card.

The eligibility floor of 13 years old is notable given the age-verification context across Europe, since it places the app in the hands of teenagers who are themselves the subject of online age-gating rules. The dependency on MitID and a CPR number ties AltID to the existing national identity base, meaning the app extends credentials to people already enrolled in the Danish digital identity system rather than creating a new enrollment path.

AltID arrives as European governments build out mobile identity wallets and as age verification becomes a recurring regulatory requirement. The European Commission has sought a privacy-preserving age verification solution built around minimal disclosure, the same design principle behind AltID’s standalone age proof, and member states have been moving national eIDs toward wallet-based credential presentation ahead of the EU Digital Identity Wallet.

The Agency for Digital Government has positioned AltID as a first version, with the digital legitimation card and age proof as the initial proofs available to eligible residents.
