Authenticate with BankID on First Login

On first login, the user selects BankID as their authentication method. The app launches an in-app browser that navigates to the BankID OIDC authorization endpoint. The user completes the BankID flow (national ID + one-time code or BankID app), after which the provider redirects back to the app with an authorization code. The BankID Integration Service exchanges this code for tokens via the BankID API Gateway using PKCE, validates the ID token, and establishes a Supabase session stored in the Auth Token Repository. The user is then directed to role selection or their home screen.

User Story

As a user
I want to log in to the app using my BankID
So that So that my identity is verified using Norway's trusted national e-ID, meeting regulatory requirements and giving organizations confidence in who is accessing sensitive data

Acceptance Criteria

  • Given a user on the login screen, when they tap 'Log in with BankID', then an in-app browser opens to the BankID authorization URL with a valid PKCE code challenge
  • Given a user who completes the BankID authentication flow, when the provider redirects with an authorization code, then the app exchanges the code for tokens and creates a valid Supabase session
  • Given a successful BankID authentication, when the session is established, then the authenticated user's name and verified identity are stored and the user is navigated to the appropriate home screen
  • Given a user who cancels the BankID flow in the browser, when the browser returns without a code, then the app returns to the login screen with a user-friendly cancellation message and no error crash
  • Given BankID provider unavailability, when the authorization endpoint returns an error, then the app displays a localized error message explaining the provider is temporarily unavailable and offers a retry action
  • Given a completed BankID login, when the app processes the ID token, then it validates the token signature, issuer, and expiry before accepting it as authentic

Business Value

BankID is the dominant national e-ID in Norway and is explicitly required by all three workshop organizations (NHF, Blindeforbundet, HLF). It provides verified identity assurance needed for regulatory compliance, protects sensitive volunteer and beneficiary data, and establishes user trust that the app is a professional-grade tool appropriate for handling personal information. Without BankID authentication, the app cannot be deployed in production for these organizations.
