+# Keycloak Configuration Issue
+
+## Problem
+
+The application is getting a `401 Unauthorized` error when trying to authenticate:
+
+```
+POST https://terminus.bluelake.cloud/realms/dalex-immo-dev/protocol/openid-connect/token 401 (Unauthorized)
+```
+
+## Root Cause
+
+The Keycloak client `dalex-proto` either:
+1. Does not exist in the `dalex-immo-dev` realm, OR
+2. Is not configured correctly for public client access
+
+## Solution
+
+You need to configure the Keycloak client on the server. Follow these steps:
+
+### Step 1: Access Keycloak Admin Console
+
+Go to: https://terminus.bluelake.cloud/admin/
+
+### Step 2: Select the Realm
+
+- Select the `dalex-immo-dev` realm from the realm dropdown
+
+### Step 3: Create or Configure the Client
+
+1. Navigate to **Clients** in the left sidebar
+2. Look for client ID `dalex-proto`
+3. If it doesn't exist, click **Create client**
+
+### Step 4: Client Configuration
+
+Configure the client with these settings:
+
+#### Basic Settings Tab
+```
+Client ID: dalex-proto
+Name: Dalex Todo Prototype
+Description: Todo application prototype
+Always display in UI: ON (optional)
+Enabled: ON
+```
+
+#### Capability Config
+```
+Client authentication: OFF (this is a public client)
+Authorization: OFF
+Authentication flow:
+  ☑ Standard flow (Authorization Code Flow)
+  ☐ Direct access grants
+  ☐ Implicit flow
+  ☐ Service accounts roles
+  ☐ OAuth 2.0 Device Authorization Grant
+```
+
+#### Access Settings
+```
+Root URL: http://localhost:3030
+Home URL: http://localhost:3030
+Valid redirect URIs: 
+  - http://localhost:3030/*
+  - http://localhost:3030
+Valid post logout redirect URIs:
+  - http://localhost:3030/*
+  - http://localhost:3030
+Web origins: 
+  - http://localhost:3030
+  - * (for development only)
+Admin URL: (leave empty)
+```
+
+#### Advanced Settings (Optional but Recommended)
+```
+Proof Key for Code Exchange Code Challenge Method: S256
+Access Token Lifespan: 5 Minutes (or as needed)
+```
+
+### Step 5: Save
+
+Click **Save** at the bottom of the page.
+
+### Step 6: Test
+
+1. Restart the application: `docker-compose restart frontend`
+2. Open http://localhost:3030
+3. You should be redirected to Keycloak login
+4. After login, you should see the todo application
+
+## Alternative: Use Existing Client
+
+If you don't have admin access to create a new client, you can use an existing public client that's typically available in Keycloak:
+
+### Option 1: Use 'account-console' client
+
+This client usually exists by default. Edit `frontend/src/keycloak.ts`:
+
+```typescript
+keycloak = new Keycloak({
+  url: 'https://terminus.bluelake.cloud/',
+  realm: 'dalex-immo-dev',
+  clientId: 'account-console'  // Changed from 'dalex-proto'
+})
+```
+
+Then rebuild: `docker-compose up --build -d`
+
+### Option 2: Use 'account' client
+
+Another default client. Edit `frontend/src/keycloak.ts`:
+
+```typescript
+keycloak = new Keycloak({
+  url: 'https://terminus.bluelake.cloud/',
+  realm: 'dalex-immo-dev',
+  clientId: 'account'  // Changed from 'dalex-proto'
+})
+```
+
+Then rebuild: `docker-compose up --build -d`
+
+## Backend Configuration
+
+Don't forget to update the backend `backend/Program.cs` to match the client ID:
+
+```csharp
+options.Audience = "dalex-proto"; // Or "account-console" or "account"
+```
+
+Then rebuild: `docker-compose up --build -d`
+
+## Verification
+
+After configuration, you should see in the browser console:
+
+```
+Initializing Keycloak...
+Keycloak config: {url: "...", realm: "dalex-immo-dev", clientId: "dalex-proto"}
+Keycloak initialized. Authenticated: true
+User authenticated successfully
+App.vue mounted, loading todos...
+```
+
+## Need Help?
+
+If you don't have admin access to Keycloak, contact your Keycloak administrator and share this document with the required client configuration.
