Authentication Configuration

Overview

This runbook covers configuring and managing authentication for Everruns.

Authentication Modes

1. No Authentication (Development)

Use for local development when authentication isn’t needed:

export AUTH_MODE=none

All requests will be allowed with full admin access.

2. Admin Mode (Simple Development)

Use for local development with basic access control:

export AUTH_MODE=admin
export AUTH_ADMIN_EMAIL=admin@example.com
export AUTH_ADMIN_PASSWORD=your-secure-password
export AUTH_JWT_SECRET=$(openssl rand -hex 32)

Only the admin user can authenticate.

3. Full Authentication (Production)

Use for production deployments:

export AUTH_MODE=full
export AUTH_BASE_URL=https://your-domain.com
export AUTH_JWT_SECRET=$(openssl rand -hex 32)

# Optional: Configure OAuth
export AUTH_GOOGLE_CLIENT_ID=your-google-client-id
export AUTH_GOOGLE_CLIENT_SECRET=your-google-client-secret
export AUTH_GITHUB_CLIENT_ID=your-github-client-id
export AUTH_GITHUB_CLIENT_SECRET=your-github-client-secret

AUTH_JWT_REFRESH_TOKEN_LIFETIME	No	Refresh token lifetime in seconds (default: 2592000)

Feature Toggles

Variable	Required	Description
AUTH_DISABLE_PASSWORD	No	Set to true to disable password login

GitHub OAuth

Variable	Required	Description
AUTH_GITHUB_CLIENT_ID	For GitHub OAuth	GitHub OAuth client ID
AUTH_GITHUB_CLIENT_SECRET	For GitHub OAuth	GitHub OAuth client secret
AUTH_GITHUB_REDIRECT_URI	No	Custom redirect URI

Common Tasks

Generate JWT Secret

# Using OpenSSL
openssl rand -hex 32

# Using Python
python3 -c "import secrets; print(secrets.token_hex(32))"

Verify Authentication is Working

# Check auth config endpoint
curl http://localhost:9000/v1/auth/config

# Should return:
# {"mode":"none","password_auth_enabled":false,"oauth_providers":[],"signup_enabled":false}

# For admin mode:
curl -X POST http://localhost:9000/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"admin@example.com","password":"your-password"}'

Create API Key

# Login first to get access token
TOKEN=$(curl -s -X POST http://localhost:9000/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"user@example.com","password":"password"}' | jq -r '.access_token')

# Create API key
curl -X POST http://localhost:9000/v1/auth/api-keys \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name":"my-api-key"}'

# Response includes full key - save it, it's shown only once

Revoke API Key

curl -X DELETE http://localhost:9000/v1/auth/api-keys/{key_id} \
  -H "Authorization: Bearer $TOKEN"

Force Logout User

Delete their refresh tokens from database:

DELETE FROM refresh_tokens WHERE user_id = 'user-uuid-here';

Troubleshooting

”Authentication required” when AUTH_MODE=none

• Verify AUTH_MODE environment variable is set correctly
• Restart the server after changing environment variables

JWT Validation Fails

• Ensure AUTH_JWT_SECRET hasn’t changed
• Check token hasn’t expired
• Verify the token is for the correct environment

OAuth Redirect Fails

• Verify AUTH_BASE_URL matches the OAuth app configuration
• Check that redirect URI in provider matches {AUTH_BASE_URL}{API_PREFIX}/v1/auth/callback/{provider}
• If using API_PREFIX, ensure it’s included in OAuth provider redirect URI configuration
• Ensure client ID and secret are correct

Password Login Returns Unauthorized

• In admin mode: check AUTH_ADMIN_EMAIL and AUTH_ADMIN_PASSWORD match
• In full mode with password disabled: check AUTH_DISABLE_PASSWORD isn’t set
• Verify user exists and password is correct

Database Migration

Authentication requires migration 003_authentication.sql:

# Run migrations
sqlx migrate run

# Or via the dev script
./scripts/dev.sh migrate

Health Check

The /health endpoint shows current auth mode:

curl http://localhost:9000/health
# {"status":"ok","version":"0.2.0","auth_mode":"None"}

Security Best Practices

1. Never commit secrets: Use environment variables or secret management
2. Rotate JWT secret: Change AUTH_JWT_SECRET periodically (invalidates all tokens)
3. Use HTTPS: Always use HTTPS in production for OAuth callbacks
4. Limit OAuth domains: Use AUTH_GOOGLE_ALLOWED_DOMAINS to restrict access
5. Monitor API key usage: Track last_used_at for suspicious activity
6. Set token expiration: Use shorter AUTH_JWT_ACCESS_TOKEN_LIFETIME for higher security
