# ADR-021: IndieAuth Provider Strategy
## Status
Accepted
## Context
StarPunk currently uses IndieLogin.com for authentication (ADR-005), but there is a critical misunderstanding about how IndieAuth works that needs to be addressed.
### The Problem
The user reported that IndieLogin.com requires manual client_id registration, making it unsuitable for self-hosted software where each installation has a different domain. This concern is based on a fundamental misunderstanding of how IndieAuth differs from traditional OAuth2.
### How IndieAuth Actually Works
Unlike traditional OAuth2 providers (GitHub, Google, etc.), **IndieAuth does not require pre-registration**:
1. **DNS-Based Client Identification**: IndieAuth uses DNS as a replacement for client registration. A client application identifies itself using its own URL (e.g., `https://starpunk.example.com`), which serves as a unique identifier.
2. **No Secrets Required**: All clients are public clients. There are no client secrets to manage or register.
3. **Dynamic Redirect URI Verification**: Instead of pre-registered redirect URIs, applications publish their valid redirect URLs at their client_id URL, which authorization servers can discover.
4. **Client Metadata Discovery**: Authorization servers can optionally fetch the client_id URL to display application information (name, logo) to users during authorization.
### StarPunk's Authentication Architecture
It is critical to understand that StarPunk has **two distinct authentication flows**:
#### Flow 1: Admin Authentication (Current Misunderstanding)
**Purpose**: Authenticate the StarPunk admin user to access the admin interface
**Current Implementation**: Uses IndieLogin.com as described in ADR-005
**How it works**:
1. Admin visits `/admin/login`
2. StarPunk redirects to IndieLogin.com with its own URL as `client_id`
3. IndieLogin.com verifies the admin's identity
4. Admin receives session cookie to access StarPunk admin
**Registration Required?** NO - IndieAuth never requires registration
#### Flow 2: Micropub Client Authorization (The Real Architecture)
**Purpose**: Allow external Micropub clients to publish to StarPunk
**How it works**:
1. User configures their personal website (e.g., `https://alice.com`) with links to StarPunk's Micropub endpoint
2. User opens Micropub client (Quill, Indigenous, etc.)
3. Client discovers authorization/token endpoints from `https://alice.com` (NOT from StarPunk)
4. Client gets access token from the discovered authorization server
5. Client uses token to POST to StarPunk's Micropub endpoint
6. StarPunk verifies the token
**Who Provides Authorization?** The USER's chosen authorization server, not StarPunk
### The Real Question
StarPunk faces two architectural decisions:
1. **Admin Authentication**: How should StarPunk administrators authenticate to the admin interface?
2. **User Authorization**: Should StarPunk provide authorization/token endpoints for its users, or should users bring their own?
## Research Findings
### Alternative IndieAuth Services
**IndieLogin.com** (Current)
- Actively maintained by Aaron Parecki (IndieAuth spec editor)
- Supports multiple auth methods: RelMeAuth, email, PGP, BlueSky OAuth (added 2025)
- **No registration required** - this was the key misunderstanding
- Free, community service
- High availability
**tokens.indieauth.com**
- Provides token endpoint functionality
- Separate from authorization endpoint
- Also maintained by IndieWeb community
- Also requires no registration
**Other Services**
- No other widely-used public IndieAuth providers found
- Most implementations are self-hosted (see below)
### Self-Hosted IndieAuth Implementations
**Taproot/IndieAuth** (PHP)
- Complexity: Moderate (7/10)
- Full-featured: Authorization + token endpoints
- PSR-7 compatible, well-tested (100% coverage)
- Lightweight dependencies (Guzzle, mf2)
- Production-ready since v0.1.0
**Selfauth** (PHP)
- Complexity: Low (3/10)
- **Limitation**: Authorization endpoint ONLY (no token endpoint)
- Cannot be used for Micropub (requires token endpoint)
- Suitable only for simple authentication use cases
**hacdias/indieauth** (Go)
- Complexity: Moderate (6/10)
- Provides both server and client libraries
- Modern Go implementation
- Used in production by author
**Custom Implementation** (Python)
- Complexity: High (8/10)
- Must implement IndieAuth spec 1.1
- Required endpoints:
- Authorization endpoint (authentication + code generation)
- Token endpoint (token issuance + verification)
- Metadata endpoint (server discovery)
- Introspection endpoint (token verification)
- Must support:
- PKCE (required by spec)
- Client metadata discovery
- Profile URL validation
- Scope-based permissions
- Token revocation
- Estimated effort: 40-60 hours for full implementation
- Ongoing maintenance burden for security updates
## Decision
**Recommendation: Continue Using IndieLogin.com with Clarified Architecture**
StarPunk should:
1. **For Admin Authentication**: Continue using IndieLogin.com (no changes needed)
- No registration required
- Works out of the box for self-hosted installations
- Each StarPunk instance uses its own domain as client_id
- Zero maintenance burden
2. **For Micropub Authorization**: Document that users must provide their own authorization server
- User configures their personal domain with IndieAuth endpoints
- User can choose:
- IndieLogin.com (easiest)
- Self-hosted IndieAuth server (advanced)
- Any other IndieAuth-compliant service
- StarPunk only verifies tokens, doesn't issue them
3. **For V2 Consideration**: Optionally provide built-in authorization server
- Would allow StarPunk to be a complete standalone solution
- Users could use StarPunk's domain as their identity
- Requires implementing full IndieAuth server (40-60 hours)
- Only pursue if there is strong user demand
## Rationale
### Why Continue with IndieLogin.com
**Simplicity Score: 10/10**
- Zero configuration required
- No registration process
- Works immediately for any domain
- Battle-tested by IndieWeb community
- The original concern (manual registration) does not exist
**Fitness Score: 10/10**
- Perfect for single-user CMS
- Aligns with IndieWeb principles
- User controls their identity
- No lock-in (user can switch authorization servers)
**Maintenance Score: 10/10**
- Externally maintained
- Security updates handled by community
- No code to maintain in StarPunk
- Proven reliability and uptime
**Standards Compliance: Pass**
- Full IndieAuth spec compliance
- OAuth 2.0 compatible
- Supports modern extensions (PKCE, client metadata)
### Why Not Self-Host (for V1)
**Complexity vs Benefit**
- Self-hosting adds 40-60 hours of development
- Ongoing security maintenance burden
- Solves a problem that doesn't exist (no registration required)
- Violates "every line of code must justify its existence"
**User Perspective**
- Users already need a domain for IndieWeb
- Most users will use IndieLogin.com or similar service
- Advanced users can self-host their own IndieAuth server
- StarPunk doesn't need to solve this problem
**Alternative Philosophy**
- StarPunk is a Micropub SERVER, not an authorization server
- Separation of concerns: publishing vs identity
- Users should control their own identity infrastructure
- StarPunk focuses on doing one thing well: publishing notes

### What StarPunk Implements
**Currently Implemented** (ADR-005):
- Session-based admin authentication via IndieLogin.com
- CSRF protection (state tokens)
- Session management
- Admin route protection
**Must Be Implemented** (for Micropub):
- Token verification endpoint (query user's token endpoint)
- Bearer token extraction from Authorization header
- Scope verification (check token has "create" permission)
- Token storage/caching (optional, for performance)
**Does NOT Implement** (users provide these):
- Authorization endpoint (users use IndieLogin.com or self-hosted)
- Token endpoint (users use tokens.indieauth.com or self-hosted)
- User identity management (users own their domains)
## Implementation Outline
### No Changes Needed for Admin Auth
The current IndieLogin.com integration (ADR-005) is correct and requires no changes. Each self-hosted StarPunk installation uses its own domain as `client_id` without any registration.
### Required for Micropub Support
#### 1. Token Verification
```python
def verify_micropub_token(bearer_token, expected_me):
"""
Verify access token by querying the token endpoint
Args:
bearer_token: Token from Authorization header
expected_me: Expected user identity (from StarPunk config)
Returns:
dict: Token info (me, client_id, scope) if valid
None: If token is invalid
"""
# Discover token endpoint from expected_me domain
token_endpoint = discover_token_endpoint(expected_me)
# Verify token
response = httpx.get(
token_endpoint,
headers={'Authorization': f'Bearer {bearer_token}'},
params={'token': bearer_token}
)
if response.status_code != 200:
return None
data = response.json()
# Verify token is for expected user
if data.get('me') != expected_me:
return None
# Verify token has required scope
scope = data.get('scope', '')
if 'create' not in scope:
return None
return data
```
#### 2. Endpoint Discovery
```python
def discover_token_endpoint(me_url):
"""
Discover token endpoint from user's profile URL
Checks for:
1. indieauth-metadata endpoint
2. Fallback to direct token_endpoint link
"""
response = httpx.get(me_url)
# Check HTTP Link header
link_header = response.headers.get('Link', '')
# Parse link header for indieauth-metadata
# Check HTML <link> tags
# Parse HTML for <link rel="indieauth-metadata">
# Fetch metadata endpoint
# Return token_endpoint URL
```
#### 3. Micropub Endpoint Protection
```python
@app.route('/api/micropub', methods=['POST'])
def micropub_endpoint():
# Extract bearer token
auth_header = request.headers.get('Authorization', '')
if not auth_header.startswith('Bearer '):
return {'error': 'unauthorized'}, 401
bearer_token = auth_header[7:] # Remove "Bearer "
# Verify token
token_info = verify_micropub_token(bearer_token, ADMIN_ME)
if not token_info:
return {'error': 'forbidden'}, 403
# Process Micropub request
# Create note
# Return 201 with Location header
```
### Documentation Updates
#### For Users (Setup Guide)
```markdown
# Setting Up Your IndieWeb Identity
To publish to StarPunk via Micropub clients:
1. **Add Links to Your Website**
Add these to your personal website's <head>:
```html
<link rel="authorization_endpoint" href="https://indielogin.com/auth">
<link rel="token_endpoint" href="https://tokens.indieauth.com/token">
<link rel="micropub" href="https://your-starpunk.example.com/api/micropub">
```
2. **Configure StarPunk**
Set your website URL in StarPunk configuration:
```
ADMIN_ME=https://your-website.com
```
3. **Use a Micropub Client**
- Quill: https://quill.p3k.io
- Indigenous (mobile app)
- Or any Micropub-compatible client
4. **Advanced: Self-Host Authorization**
Instead of IndieLogin.com, you can run your own IndieAuth server.
See: https://indieweb.org/IndieAuth#Software
```
#### For Developers (Architecture Docs)
Update `/home/phil/Projects/starpunk/docs/architecture/overview.md` to clarify the two authentication flows and explain that StarPunk is a Micropub server, not an authorization server.
## Consequences
### Positive
- **No development needed**: Current architecture is correct
- **No registration required**: Works for self-hosted installations out of the box
- **User control**: Users choose their own authorization provider
- **Standards compliant**: Proper separation of Micropub server and authorization server
- **Simple**: StarPunk focuses on publishing, not identity management
- **Flexible**: Users can switch authorization providers without affecting StarPunk
### Negative
- **User education required**: Must explain that they need to configure their domain
- **Not standalone**: StarPunk cannot function completely independently (requires external auth)
- **Dependency**: Relies on external services (mitigated: user chooses service)
### Neutral
- **Architectural purity**: Follows IndieWeb principle of separation of concerns
- **Complexity distribution**: Moves authorization complexity to where it belongs (identity provider)
## V2 Considerations
If there is user demand for a more integrated solution, V2 could add:
### Option A: Embedded IndieAuth Server
**Pros**:
- StarPunk becomes completely standalone
- Users can use StarPunk domain as their identity
- One-step setup for non-technical users
**Cons**:
- 40-60 hours development effort
- Ongoing security maintenance
- Adds complexity to codebase
- May violate simplicity principle
**Decision**: Only implement if users request it
### Option B: Hybrid Mode
**Pros**:
- Advanced users can use external auth (current behavior)
- Simple users can use built-in auth
- Best of both worlds
**Cons**:
- Even more complexity
- Two codepaths to maintain
- Configuration complexity
**Decision**: Defer until V2 user feedback
### Option C: StarPunk-Hosted Service
**Pros**:
- One StarPunk authorization server for all installations
- Users register their StarPunk instance once
- Simple for end users
**Cons**:
- Centralized service (not indie)
- Single point of failure
- Hosting/maintenance burden
- Violates IndieWeb principles
**Decision**: Rejected - not aligned with IndieWeb values
## Alternatives Considered
### Alternative 1: Self-Host IndieAuth (Taproot/PHP)
**Evaluation**:
- Complexity: Would require running PHP alongside Python
- Deployment: Two separate applications to manage
- Maintenance: Security updates for both Python and PHP
- Verdict: **Rejected** - adds unnecessary complexity
### Alternative 2: Port Taproot to Python
**Evaluation**:
- Effort: 40-60 hours development
- Maintenance: Full responsibility for security
- Value: Solves a non-existent problem (no registration needed)
- Verdict: **Rejected** - violates simplicity principle
### Alternative 3: Use OAuth2 Service (GitHub, Google)
**Evaluation**:
- Simplicity: Very simple to implement
- IndieWeb Compliance: **FAIL** - not IndieWeb compatible
- User Ownership: **FAIL** - users don't own their identity
- Verdict: **Rejected** - violates core requirements
### Alternative 4: Password Authentication
**Evaluation**:
- Simplicity: Moderate (password hashing, reset flows)
- IndieWeb Compliance: **FAIL** - not IndieWeb authentication
- Security: Must implement password best practices
- Verdict: **Rejected** - not aligned with IndieWeb principles
### Alternative 5: Use IndieAuth as Library (Client Side)
**Evaluation**:
- Would make StarPunk act as IndieAuth client to discover user's auth server
- Current architecture already does this for Micropub
- Admin interface uses simpler session-based auth
- Verdict: **Already implemented** for Micropub flow
## Migration Plan
### From Current Broken Understanding → Correct Understanding
**No Code Changes Required**
1. **Update Documentation**
- Clarify that no registration is needed
- Explain the two authentication flows
- Document Micropub setup for users
2. **Complete Micropub Implementation**
- Implement token verification
- Implement endpoint discovery
- Add Bearer token authentication
3. **User Education**
- Create setup guide explaining domain configuration
- Provide example HTML snippets
- Link to IndieWeb resources
### Timeline
- Documentation updates: 2 hours
- Micropub token verification: 8 hours
- Testing with real Micropub clients: 4 hours
- Total: ~14 hours
