CloudDesk EDU supports passwordless authentication using WebAuthn passkeys. Users can sign in using biometrics (Face ID, Touch ID, Windows Hello) or security keys (YubiKey, Titan Key).
- Standalone Passkey Login: Sign in using only a passkey without Google OAuth
- 2FA Mode: Require passkey verification after Google login for enhanced security
- Multiple Authenticators: Users can register multiple passkeys (platform and cross-platform)
- Passkey Management: Enroll, rename, and delete passkeys from profile settings
- Phishing-Resistant: Public key cryptography prevents credential theft and phishing
WebAuthn requires three environment variables in server/.env:
# Relying Party ID - must match your domain
RP_ID=localhost # Development
# RP_ID=example.com # Production
# Relying Party Name - shown to users
RP_NAME=CloudDesk
# Expected Origin - complete URL with protocol
ORIGIN=http://localhost:5173 # Development
# ORIGIN=https://example.com # Production (MUST use HTTPS)RP_ID (Relying Party ID):
- Must match your domain name (without protocol or port)
- Development:
localhost - Production:
example.comorapp.example.com - Cannot include
http://,https://, or port numbers - CRITICAL: Changing this value invalidates all existing passkeys
ORIGIN (Expected Origin):
- Must be the complete URL where users access your application
- Must include protocol (
http://orhttps://) - Must include port for non-standard ports (e.g.,
:5173) - Production MUST use HTTPS (WebAuthn requires secure context)
- Must match exactly what appears in the browser address bar
RP_NAME (Relying Party Name):
- Human-readable name displayed to users during passkey enrollment
- Shown in browser prompts and authenticator interfaces
- Should be your application or company name
Development Setup:
RP_ID=localhost
RP_NAME=CloudDesk Dev
ORIGIN=http://localhost:5173Production Setup (Root Domain):
RP_ID=example.com
RP_NAME=CloudDesk
ORIGIN=https://example.comProduction Setup (Subdomain):
RP_ID=app.example.com
RP_NAME=CloudDesk
ORIGIN=https://app.example.comPasskey authentication requires additional database tables. Run migrations to create them:
cd server
npm run migrateThis creates:
passkeystable - Stores user credentials and metadatawebauthn_challengestable - Temporary challenge storage (5-minute expiration)passkey_2fa_enabledcolumn inapproved_userstable
WebAuthn is supported in:
- ✅ Chrome/Edge 67+
- ✅ Firefox 60+
- ✅ Safari 13+
- ✅ iOS Safari 14+
- ✅ Android Chrome 70+
The application automatically detects WebAuthn support and gracefully hides passkey options in unsupported browsers.
- Challenge-Response: Cryptographically random challenges prevent replay attacks
- Counter Validation: Detects cloned authenticators by tracking signature counters
- Origin Verification: Prevents cross-origin and phishing attacks
- Signature Validation: Cryptographic proof that user possesses the private key
- User Verification: Requires biometric or PIN for authentication
- 5-Minute Challenge Expiration: Prevents stale challenge reuse
"WebAuthn not supported" error:
- Ensure you're using HTTPS in production (required by WebAuthn spec)
- Check browser compatibility (see Browser Compatibility Guide)
- Verify you're in a secure context (localhost or HTTPS)
- Update to a modern browser: Chrome 67+, Firefox 60+, Safari 13+
"Origin mismatch" error:
- Verify
ORIGINenvironment variable matches browser URL exactly - Include protocol (
http://orhttps://) - Include port if non-standard (e.g.,
:5173) - Check for trailing slashes (should not be included)
"RP_ID mismatch" error:
- Ensure
RP_IDmatches your domain without protocol - Cannot use IP addresses in production
- Subdomains must match exactly (e.g.,
app.example.comnotexample.com)
"Challenge expired" error:
- Challenges expire after 5 minutes for security
- User must complete authentication promptly
- Check server time synchronization (NTP)
Passkeys not working after deployment:
- Verify all three environment variables are set correctly
- Ensure production uses HTTPS
- Check that
RP_IDmatches your production domain - Review server logs for detailed error messages
For more details, see the WebAuthn section in server/README.md.
CloudDesk EDU uses Indonesian Rupiah (IDR) for all pricing. If you have existing billing data in USD, use the migration scripts:
cd server
# Step 1: Test migration (safe, no real data changed)
npm run migrate:currency:test
# Step 2: Run migration (converts USD to IDR at 1 USD = 16,600 IDR)
npm run migrate:currency
# Step 3: Verify results
npm run migrate:currency:verifyFeatures:
- ✅ Automatic backup creation before migration
- ✅ Interactive confirmation prompts
- ✅ Comprehensive verification
- ✅ Idempotent (safe to run multiple times)
- ✅ Rollback instructions provided
Note: If you're starting fresh with no existing billing data, you don't need to run the migration. The application is already configured for IDR.
For detailed instructions, see MIGRATION-GUIDE.md.
CloudDesk EDU supports real Google Cloud Platform VM provisioning for production deployments. When enabled, the system provisions actual Windows-based virtual machines in GCP instead of using demo mode.
-
Google Cloud Platform Account
- Active GCP project with billing enabled
- gcloud SDK installed on the server
- Service account with appropriate permissions
-
Required GCP APIs
Enable the following APIs in your GCP project:
gcloud services enable compute.googleapis.com gcloud services enable cloudresourcemanager.googleapis.com
-
Install gcloud SDK
Follow the official installation guide for your operating system:
# Verify installation gcloud --version # Authenticate with service account gcloud auth activate-service-account --key-file=/path/to/service-account-key.json # Set default project gcloud config set project YOUR_PROJECT_ID
Create a service account with the following IAM roles:
Compute Engine Permissions:
compute.instances.create- Create VM instancescompute.instances.delete- Delete VM instancescompute.instances.get- Query instance status and detailscompute.instances.list- List instances in projectcompute.instances.start- Start stopped instancescompute.instances.stop- Stop running instancescompute.instances.setMetadata- Required for Windows password resetcompute.disks.create- Create boot disks for instancescompute.images.useReadOnly- Use Windows Server imagescompute.zones.get- Access zone information
Recommended IAM Role:
The easiest approach is to assign the Compute Instance Admin (v1) role (roles/compute.instanceAdmin.v1) to your service account:
# Create service account
gcloud iam service-accounts create clouddesk-compute \
--display-name="CloudDesk Compute Service Account"
# Grant Compute Instance Admin role
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
--member="serviceAccount:clouddesk-compute@YOUR_PROJECT_ID.iam.gserviceaccount.com" \
--role="roles/compute.instanceAdmin.v1"
# Create and download service account key
gcloud iam service-accounts keys create ~/clouddesk-sa-key.json \
--iam-account=clouddesk-compute@YOUR_PROJECT_ID.iam.gserviceaccount.comCustom Role (Advanced):
For fine-grained control, create a custom role with only the required permissions:
# Create custom role
gcloud iam roles create cloudDeskComputeRole \
--project=YOUR_PROJECT_ID \
--title="CloudDesk Compute Role" \
--description="Custom role for CloudDesk VM management" \
--permissions=compute.instances.create,compute.instances.delete,compute.instances.get,compute.instances.list,compute.instances.start,compute.instances.stop,compute.instances.setMetadata,compute.disks.create,compute.images.useReadOnly,compute.zones.get
# Assign custom role to service account
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
--member="serviceAccount:clouddesk-compute@YOUR_PROJECT_ID.iam.gserviceaccount.com" \
--role="projects/YOUR_PROJECT_ID/roles/cloudDeskComputeRole"-
Set Environment Variables
Update
server/.env:GCP_PROJECT_ID=your-gcp-project-id GCP_ENABLED=true
-
Authenticate gcloud SDK
On your server, authenticate using the service account:
gcloud auth activate-service-account \ --key-file=/path/to/clouddesk-sa-key.json
-
Verify Configuration
Test that gcloud is properly configured:
# List available zones gcloud compute zones list # Verify authentication gcloud auth list # Check project configuration gcloud config get-value project
-
Start the Server
The server will automatically detect GCP configuration on startup:
cd server npm startLook for the log message:
✓ GCP Compute Engine integration enabled ✓ Project: your-gcp-project-id
CloudDesk currently supports VM provisioning in two GCP regions:
| CloudDesk Region | GCP Region | GCP Zone | Location |
|---|---|---|---|
| SINGAPORE | asia-southeast1 | asia-southeast1-a | Singapore |
| IOWA | us-central1 | us-central1-a | Iowa, USA |
When GCP integration is enabled:
- ✅ Real VM Provisioning: Creates actual Windows Server VMs in GCP
- ✅ Windows Password Reset: Generate and retrieve Windows administrator passwords
- ✅ Instance Lifecycle Management: Start, stop, and delete VMs
- ✅ Status Synchronization: Real-time status updates from GCP
- ✅ External IP Assignment: Automatic public IP allocation
- ✅ Error Handling: Comprehensive error messages for GCP operations
- ✅ Audit Logging: All GCP operations logged with context
Demo Mode (GCP_ENABLED=false):
- Uses database-only instance management
- No actual VMs provisioned
- Instant operations (no waiting)
- No GCP costs
- Perfect for development and testing
Production Mode (GCP_ENABLED=true):
- Provisions real Windows Server VMs in GCP
- 5-10 minute provisioning time
- Actual compute costs apply
- Full Windows desktop functionality
- Requires GCP credentials
"gcloud command not found"
- Ensure gcloud SDK is installed and in your PATH
- Restart your terminal after installation
"Authentication failed"
- Verify service account key is valid
- Check that service account has required permissions
- Re-authenticate:
gcloud auth activate-service-account --key-file=...
"Quota exceeded"
- Check your GCP project quotas in the console
- Request quota increases if needed
- Try a different region
"Permission denied"
- Verify service account has Compute Instance Admin role
- Check that required APIs are enabled
- Review IAM policy bindings
"Instance creation timeout"
- GCP VM provisioning can take 5-10 minutes
- Check GCP Console for instance status
- Review server logs for detailed error messages
GCP charges apply for:
- Compute: Per-second billing for VM instances
- Storage: Boot disk storage (minimum 50GB for Windows)
- Network: Egress traffic (ingress is free)
- Licensing: Windows Server license included in machine cost
Estimate costs using the GCP Pricing Calculator.
Cost Optimization Tips:
- Stop instances when not in use (storage costs only)
- Use preemptible VMs for non-critical workloads (not yet supported)
- Choose appropriate machine types (don't over-provision)
- Monitor usage with CloudDesk analytics
