Auth Package

This package provides OAuth 2.0 authentication for Lesser, enabling secure access to local user accounts.

Overview

The auth package implements:

  • OAuth 2.0 with PKCE (Proof Key for Code Exchange) for enhanced security
  • JWT (JSON Web Token) based access tokens
  • Refresh token support for long-lived sessions
  • Middleware for protecting endpoints
  • Scope-based authorization

Lesser is passwordless by design: users authenticate via WebAuthn/passkeys and/or wallet signatures. OAuth tokens are still presented as Authorization: Bearer …, but Lesser does not support password-based login or password grant flows.

Components

OAuthService

The main OAuth service that handles:

  • Client validation
  • Authorization code generation
  • PKCE verification
  • Token generation and validation
  • JWT signing and verification
Middleware

Authentication middleware that:

  • Extracts and validates JWT tokens from requests
  • Provides user context to handlers
  • Enforces scope requirements
  • Validates user ownership of resources

Usage

Basic Setup
import "github.com/equaltoai/lesser/pkg/auth"

// Create OAuth service
oauthSvc := auth.NewOAuthService("your-jwt-secret")

// Register a client
oauthSvc.RegisterClient(&auth.Client{
    ID:          "my-app",
    Secret:      "client-secret",
    Name:        "My Application",
    RedirectURI: "https://myapp.com/callback",
})
Protecting Endpoints
// Create middleware
authMiddleware := auth.NewMiddleware()

// In your Lambda handler
func handler(ctx context.Context, request events.APIGatewayProxyRequest) (events.APIGatewayProxyResponse, error) {
    // Verify authentication
    claims, err := authMiddleware.RequireAuth(ctx, request)
    if err != nil {
        return common.Unauthorized(err), nil
    }
    
    // Check user matches resource owner
    if err := authMiddleware.RequireUser(claims, username); err != nil {
        return common.Forbidden(err), nil
    }
    
    // Check required scope
    if err := authMiddleware.RequireScope(claims, auth.ScopeWrite); err != nil {
        return common.Forbidden(err), nil
    }
    
    // User is authenticated and authorized
    // ... handle request ...
}
OAuth Flow

  1. Authorization Request

    GET /oauth/authorize?
  response_type=code&
  client_id=my-app&
  redirect_uri=https://myapp.com/callback&
  code_challenge=CHALLENGE&
  code_challenge_method=S256&
  scope=read write&
  state=RANDOM_STATE

  2. User Authorization

    • Users authenticate via the passwordless auth UI (WebAuthn/passkeys and/or wallet challenge + signature).
    • See docs/architecture/auth/PASSWORDLESS_OAUTH.md for the end-to-end flow and endpoints.

  3. Authorization Code Response

    HTTP/1.1 302 Found
Location: https://myapp.com/callback?code=AUTH_CODE&state=RANDOM_STATE

  4. Token Exchange

    POST /oauth/token
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&
code=AUTH_CODE&
client_id=my-app&
client_secret=client-secret&
code_verifier=VERIFIER&
redirect_uri=https://myapp.com/callback

  5. Token Response

    {
  "access_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
  "token_type": "Bearer",
  "expires_in": 3600,
  "refresh_token": "REFRESH_TOKEN",
  "scope": "read write"
}

Security Considerations

PKCE Required

All authorization requests must include PKCE parameters:

  • code_challenge: Base64URL encoded SHA256 hash of the code verifier
  • code_challenge_method: Must be "S256"
  • code_verifier: Random string used in token exchange
Token Expiration
  • Access tokens expire after 1 hour
  • Refresh tokens expire after 30 days
  • Authorization codes expire after 10 minutes
JWT Claims

Access tokens include:

{
  "sub": "username",
  "username": "username",
  "client_id": "my-app",
  "scopes": ["read", "write"],
  "iat": 1234567890,
  "exp": 1234571490
}

Scopes

  • read: Read access to user data
  • write: Write access to create/update activities

Storage

OAuth data is stored in DynamoDB:

  • Authorization codes: PK=AUTHCODE#{code}, SK=CODE
  • Refresh tokens: PK=REFRESHTOKEN#{token}, SK=TOKEN

Both include automatic expiration handling.

Configuration

Environment variables:

  • JWT_SECRET: Secret key for signing JWT tokens (required in production)

Testing

# Run OAuth package tests
go test ./pkg/auth/...

# Run OAuth storage tests
GO_ENV=test go test ./pkg/storage/dynamodb/... -run OAuth

Future Enhancements

  1. User Authentication

    • Expand passwordless login UI (passkeys/wallets)
    • Account recovery UX (recovery codes / social recovery)
    • Multi-factor authentication (passwordless-friendly)

  2. Client Management

    • Dynamic client registration
    • Client credentials from database
    • Multiple redirect URIs per client

  3. Advanced OAuth Features

    • OpenID Connect support
    • Token introspection endpoint
    • Token revocation endpoint
    • Client credentials grant type

  4. Security Enhancements

    • Rate limiting
    • Brute force protection
    • Token rotation on refresh
    • Encrypted token storage
