+The plugin forwards all requests under `/api/v1/auth/*` directly to better-auth's universal handler. Better-auth provides the following endpoints:
+
+### Email/Password Authentication
+- `POST /api/v1/auth/sign-in/email` - Sign in with email and password
+- `POST /api/v1/auth/sign-up/email` - Register new user with email and password
+- `POST /api/v1/auth/sign-out` - Sign out current user
+
+### Session Management
+- `GET /api/v1/auth/get-session` - Get current user session
+
+### Password Management
+- `POST /api/v1/auth/forget-password` - Request password reset email
+- `POST /api/v1/auth/reset-password` - Reset password with token
+
+### Email Verification
+- `POST /api/v1/auth/send-verification-email` - Send verification email
+- `GET /api/v1/auth/verify-email` - Verify email with token
+
+### OAuth (when providers configured)
+- `GET /api/v1/auth/authorize/[provider]` - Start OAuth flow
+- `GET /api/v1/auth/callback/[provider]` - OAuth callback
+
+### 2FA (when enabled)
+- `POST /api/v1/auth/two-factor/enable` - Enable 2FA
+- `POST /api/v1/auth/two-factor/verify` - Verify 2FA code
 
-- `POST /api/v1/auth/login` - User login with email/password
-- `POST /api/v1/auth/register` - User registration
-- `POST /api/v1/auth/logout` - User logout
-- `GET /api/v1/auth/session` - Get current session
+### Passkeys (when enabled)
+- `POST /api/v1/auth/passkey/register` - Register a passkey
+- `POST /api/v1/auth/passkey/authenticate` - Authenticate with passkey
 
-**Note:** Routes are currently wired up and returning placeholder responses while better-auth API integration is completed. OAuth provider routes will be added in upcoming releases.
+### Magic Links (when enabled)
+- `POST /api/v1/auth/magic-link/send` - Send magic link email
+- `GET /api/v1/auth/magic-link/verify` - Verify magic link

+
+### Architecture
+
+The plugin uses a **direct forwarding** approach:
+
+```typescript
+// All requests under /api/v1/auth/* are forwarded to better-auth
+rawApp.all('/api/v1/auth/*', async (c) => {
+  const request = c.req.raw; // Web standard Request
+  const response = await authManager.handleRequest(request);
+  return response; // Web standard Response
+});
+```
+
+This architecture provides:
+- ✅ **Minimal code** - No custom route implementations
+- ✅ **Full compatibility** - All better-auth features work automatically
+- ✅ **Easy updates** - Better-auth updates don't require code changes
+- ✅ **Type safety** - Full TypeScript support from better-auth
+- ✅ **Programmatic API** - Access auth methods via `authManager.api`
