AltID Wallet

AltID is Denmark's official app for ID and proofs. It lets users create and present digital proof from their mobile device, including an identity card and age proof in the first version of the app.

The integration follows the standard eID Easy OIDC flow. This page covers only what is specific to AltID: prerequisites, the user-facing steps, the identity claims returned, and the current public app requirements.

Prerequisites

Before starting, ensure the following are in place:

1. You have a working OIDC client set up on test.eideasy.com with a registered redirect_uri.
2. AltID is enabled for your client in the eID Easy admin panel.
3. You have configured your JWK public key for private_key_jwt authentication. If not yet done, send us your client_id and your JWKs JSON or public JWKs URL so we can configure it for you.
4. You have access to the AltID sandbox.
5. The AltID app is installed and ready on your test device. See Setting up AltID below.

Testing in the playground

You can test this wallet through the eID Easy EUDI Wallet playground: http://eudiw-playground.eideasy.com/.

Running the flow

1. Start the authorization request

Follow Step 1 of the OIDC guide and include the pid scope to request verified identity claims:

scope=openid profile pid

2. Select the wallet on the authorization page

Once the eID Easy authorization page opens:

1. Select Denmark as the country
2. Choose AltID as the method

3. Complete the wallet authentication

On the AltID screen:

1. Scan the QR code with the AltID app, or open the wallet directly if you are using the same mobile device
2. Review the identity or age-proof attributes requested by the relying party
3. Approve the data sharing request in the wallet

Once approved, the wallet redirects back to eID Easy, which redirects your user to your redirect_uri with an authorization code.

4. Exchange the code and validate the ID token

Follow Steps 3-5 of the OIDC guide to exchange the code and validate the returned ID token.

The ID token is a signed JWS. Verify it using the public key published via the discovery document:

https://test.eideasy.com/.well-known/jwks.json

Identity claims returned

When the user successfully authenticates with AltID, the ID token includes a verified_claims object with government-issued identity data:

{
  "verified_claims": {
    "verification": {
      "trust_framework": "eidas",
      "time": "2026-03-11 12:29:34",
      "evidence": [
        {
          "type": "electronic_record",
          "document_details": {
            "type": "EudiPid"
          }
        }
      ]
    },
    "claims": {
      "given_name": "Sofie",
      "family_name": "Jensen",
      "birthdate": "1991-06-18",
      "nationalities": ["DK"],
      "birth_place": {
        "country": "DK",
        "locality": "Copenhagen"
      }
    }
  }
}

Field	Description
verification.trust_framework	Always eidas for EUDI Wallet credentials
verification.time	Timestamp of when the verification was performed
verification.evidence[].type	electronic_record for wallet-issued PID
verification.evidence[].document_details.type	EudiPid for EU Digital Identity PID credentials

TIP

Standard profile claims (name, given_name, family_name, birthdate) may also appear at the top level of the ID token payload alongside verified_claims.
