🎯 Latar Belakang & Masalah

Masalah Awal

1. Token Sanctum bersifat permanent (expiration = null)

   • Credential yang bocor valid selamanya sampai dihapus manual
   • Tidak ada mekanisme rotasi/revoke yang proper

2. Dampak Security

   • Unauthorized access bisa terjadi lama sekali bila token bocor
   • Tidak comply dengan best practice dan compliance requirements
   • Tidak ada tracking penggunaan token (IP, device)

3. Tidak Ada Refresh Token

   • User harus login ulang jika token expired
   • Poor user experience untuk aplikasi mobile/SPA

Kebutuhan

• Token otomatis expired setelah waktu tertentu
• Mekanisme refresh token untuk UX yang lebih baik
• Tracking metadata (IP, user agent) untuk anomaly detection
• API untuk revoke/rotate token

---

✅ Solusi yang Diimplementasikan

1. Token Expiration

• Access token expired setelah 24 jam (configurable)
• Refresh token valid selama 30 hari (configurable)

2. Refresh Token Mechanism

• Single-use refresh token (otomatis revoked setelah dipakai)
• Refresh token baru issued setiap kali refresh
• Support logout single device atau all devices

3. Token Metadata Tracking

• IP address tracking
• User agent tracking
• Last used timestamp

4. Anomaly Detection

• Deteksi perubahan IP address
• Deteksi perubahan user agent (device berbeda)
• Activity logging untuk security audit

5. Token Management API

• List tokens
• Revoke specific token
• Rotate token
• Revoke all tokens

⚙️ Perubahan Konfigurasi

config/sanctum.php

'expiration' => 1440, // Token expired dalam 24 jam (1440 menit)

Sebelum: 'expiration' => null (tidak pernah expired)
Sesudah: 'expiration' => 1440 (24 jam)

config/auth.php

// Refresh Token Lifetime Configuration
'refresh_token_lifetime' => env('REFRESH_TOKEN_LIFETIME', 2592000), // 30 days
'refresh_token_lifetime_days' => env('REFRESH_TOKEN_LIFETIME_DAYS', 30),

.env (Optional - untuk override)

REFRESH_TOKEN_LIFETIME=2592000        # 30 hari dalam detik
REFRESH_TOKEN_LIFETIME_DAYS=30        # 30 hari

---

🗄️ Database Changes

Migration 1: Add Metadata to Personal Access Tokens

File: database/migrations/2026_03_12_085615_add_metadata_to_personal_access_tokens_table.php

Schema::table('personal_access_tokens', function (Blueprint $table) {
    $table->string('ip_address', 45)->nullable()->after('last_used_at');
    $table->text('user_agent')->nullable()->after('ip_address');
    $table->index(['tokenable_type', 'tokenable_id', 'name']);
});

Kolom Baru:

• ip_address (string, 45) - IP address saat token dibuat
• user_agent (text) - User agent browser/device

Migration 2: Create Refresh Tokens Table

File: database/migrations/2026_03_12_100843_create_refresh_tokens_table.php

Schema::create('refresh_tokens', function (Blueprint $table) {
    $table->id();
    $table->foreignId('user_id')->constrained()->onDelete('cascade');
    $table->string('refresh_token', 100)->unique();
    $table->string('access_token_id')->nullable();
    $table->string('ip_address', 45)->nullable();
    $table->text('user_agent')->nullable();
    $table->timestamp('expires_at');
    $table->boolean('is_revoked')->default(false);
    $table->timestamp('revoked_at')->nullable();
    $table->string('revoked_reason')->nullable();
    $table->timestamps();

    $table->index(['user_id', 'is_revoked']);
    $table->index('refresh_token');
    $table->index('expires_at');
});

Kolom:

• user_id - Foreign key ke users table
• refresh_token - Random string 100 karakter
• access_token_id - Reference ke personal_access_tokens
• ip_address - IP saat refresh token dibuat
• user_agent - User agent saat refresh token dibuat
• expires_at - Waktu expired (30 hari dari creation)
• is_revoked - Flag apakah token sudah dicabut
• revoked_at - Waktu pencabutan
• revoked_reason - Alasan pencabutan ('logout', 'token_refresh', 'security')

---

📦 New Models

app/Models/RefreshToken.php

class RefreshToken extends Model
{
    protected $fillable = [
        'user_id',
        'refresh_token',
        'access_token_id',
        'ip_address',
        'user_agent',
        'expires_at',
        'is_revoked',
        'revoked_at',
        'revoked_reason',
    ];

    protected $casts = [
        'expires_at' => 'datetime',
        'revoked_at' => 'datetime',
        'is_revoked' => 'boolean',
    ];

    // Methods
    public function user(): BelongsTo
    public function isExpired(): bool
    public function isValid(): bool
    public function revoke(string $reason = null): void
}

app/Models/User.php (Updated)

Tambah relasi refreshTokens:

public function refreshTokens()
{
    return $this->hasMany(RefreshToken::class);
}

---

🎮 Controllers Updates

app/Http/Controllers/Api/Auth/AuthController.php

Perubahan pada method login():

public function login(Request $request)
{
    // ... authentication logic ...
    
    // Revoke all existing tokens
    $user->tokens()->delete();
    $user->refreshTokens()->delete();

    // Create new access token
    $newToken = $user->createToken('auth_token');
    $tokenModel = PersonalAccessToken::find($newToken->accessToken->id);
    $tokenModel->forceFill([
        'ip_address' => $request->ip(),
        'user_agent' => $request->userAgent(),
        'expires_at' => now()->addMinutes(config('sanctum.expiration')),
    ]);
    $tokenModel->save();

    // Create refresh token
    $refreshToken = RefreshToken::create([
        'user_id' => $user->id,
        'refresh_token' => Str::random(100),
        'access_token_id' => $tokenModel->id,
        'ip_address' => $request->ip(),
        'user_agent' => $request->userAgent(),
        'expires_at' => now()->addDays(config('auth.refresh_token_lifetime_days', 30)),
    ]);

    return response()->json([
        'message' => 'Login Success',
        'access_token' => $token,
        'refresh_token' => $refreshToken->refresh_token,
        'token_type' => 'Bearer',
        'expires_in' => config('sanctum.expiration') * 60,
        'refresh_expires_in' => config('auth.refresh_token_lifetime', 2592000),
    ]);
}

Response Login Baru:

{
  "message": "Login Success",
  "access_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
  "refresh_token": "random_100_char_string_xyz",
  "token_type": "Bearer",
  "expires_in": 86400,
  "refresh_expires_in": 2592000
}

app/Http/Controllers/Api/TokenController.php (New)

Endpoints:

• index() - List all user tokens
• show($tokenId) - Get token details
• revoke() - Revoke specific token
• rotate() - Rotate token (revoke + create new)
• revokeAll() - Revoke all except current
• revokeAllIncludingCurrent() - Revoke all tokens

Contoh method rotate():

public function rotate(RotateTokenRequest $request): JsonResponse
{
    $user = $request->user();
    $validated = $request->validated();
    $tokenId = $validated['token_id'];
    $tokenName = $validated['token_name'] ?? 'rotated_token';

    $oldToken = $user->tokens()->find($tokenId);
    $abilities = $oldToken->abilities ?? ['*'];

    // Create new token
    $newToken = $user->createToken($tokenName, $abilities);
    $newTokenModel = PersonalAccessToken::find($newToken->accessToken->id);
    $newTokenModel->forceFill([
        'ip_address' => $request->ip(),
        'user_agent' => $request->userAgent(),
        'expires_at' => now()->addMinutes(config('sanctum.expiration')),
    ]);
    $newTokenModel->save();

    // Revoke old token
    $oldToken->delete();

    return response()->json([
        'message' => 'Token berhasil dirotasi',
        'data' => [
            'access_token' => $newToken->plainTextToken,
            'token_type' => 'Bearer',
            'expires_in' => config('sanctum.expiration') * 60,
        ],
    ]);
}

app/Http/Controllers/Api/RefreshTokenController.php (New)

Endpoints:

• refresh() - Refresh access token using refresh token
• revoke() - Logout single device
• revokeAll() - Logout all devices

Method refresh():

public function refresh(RefreshTokenRequest $request): JsonResponse
{
    $refreshToken = RefreshToken::where('refresh_token', $refreshTokenString)->first();

    // Validate refresh token
    if (! $refreshToken->isValid()) {
        return response()->json([
            'message' => 'Refresh token telah expired/dicabut',
        ], 403);
    }

    $user = $refreshToken->user;

    // Revoke old tokens (single use)
    $refreshToken->revoke('token_refresh');
    if ($refreshToken->access_token_id) {
        PersonalAccessToken::find($refreshToken->access_token_id)?->delete();
    }

    // Create new access token
    $newAccessToken = $user->createToken('auth_token');
    // ... update metadata ...

    // Create new refresh token
    $newRefreshToken = $this->createRefreshToken($user, $newAccessTokenModel->id, $request);

    return response()->json([
        'message' => 'Token berhasil di-refresh',
        'data' => [
            'access_token' => $newAccessToken->plainTextToken,
            'refresh_token' => $newRefreshToken->refresh_token,
            'token_type' => 'Bearer',
            'expires_in' => 86400,
            'refresh_expires_in' => 2592000,
        ],
    ]);
}

🛡️ Middleware

app/Http/Middleware/DetectTokenAnomaly.php (New)

Fungsi: Deteksi anomali penggunaan token (IP/device berubah)

Logic:

public function handle(Request $request, Closure $next): Response
{
    $user = $request->user();
    $currentToken = $user->currentAccessToken();

    $currentIp = $request->ip();
    $currentUserAgent = $request->userAgent();
    $storedIp = $currentToken->ip_address;
    $storedUserAgent = $currentToken->user_agent;

    $anomalies = [];

    // Check IP change
    if ($storedIp && $storedIp !== $currentIp) {
        $anomalies[] = 'ip_address_changed';
        Log::warning('Token IP anomaly detected', [...]);
    }

    // Check User Agent change
    if ($storedUserAgent && $storedUserAgent !== $currentUserAgent) {
        $anomalies[] = 'user_agent_changed';
        Log::warning('Token User Agent anomaly detected', [...]);
    }

    // Update metadata if anomalies detected
    if (! empty($anomalies)) {
        $currentToken->forceFill([
            'ip_address' => $currentIp,
            'user_agent' => $currentUserAgent,
        ]);
        $currentToken->save();

        // Log to activity log
        activity('token_anomaly')
            ->causedBy($user)
            ->withProperties([...])
            ->log('Anomali penggunaan token terdeteksi');
    }

    return $next($request);
}

app/Http/Middleware/AuthApiOptional.php (New)

Fungsi: Middleware hybrid untuk API yang bisa diakses via session ATAU token

Use Case: Dashboard admin yang mengakses API endpoint

public function handle(Request $request, Closure $next): Response
{
    // Try session auth first (admin dashboard)
    if (Auth::check()) {
        return $next($request);
    }

    // Try Sanctum token auth (API clients)
    if ($request->bearerToken()) {
        $user = Auth::guard('sanctum')->user();
        if ($user) {
            return $next($request);
        }
    }

    return response()->json(['message' => 'Unauthenticated'], 401);
}

app/Http/Kernel.php (Updated)

Tambah middleware aliases:

protected $routeMiddleware = [
    // ... existing middleware ...
    'token.anomaly' => Middleware\DetectTokenAnomaly::class,    
];

---

🛣️ Routes

routes/apiv1.php (Updated)

// Token Management (requires auth:sanctum)
Route::middleware(['auth:sanctum', 'token.anomaly'])->group(function () {
    Route::get('/user', function (Request $request) {
        return $request->user();
    });

    // Token Management
    Route::prefix('tokens')->group(function () {
        Route::get('/', [TokenController::class, 'index']);
        Route::get('/{tokenId}', [TokenController::class, 'show']);
        Route::post('/revoke', [TokenController::class, 'revoke']);
        Route::post('/rotate', [TokenController::class, 'rotate']);

        Route::post('/revoke-all-including-current', [TokenController::class, 'revokeAllIncludingCurrent']);
    });        
});

// Refresh Token Management
    Route::prefix('refresh-token')->group(function () {
        Route::post('/refresh', [RefreshTokenController::class, 'refresh']);
        Route::post('/revoke', [RefreshTokenController::class, 'revoke']);
        Route::post('/revoke-all', [RefreshTokenController::class, 'revokeAll'])
            ->middleware('auth:sanctum');
    });

📊 Impact Analysis

Admin Dashboard

• ✅ NO IMPACT - Admin dashboard menggunakan session auth (auth middleware)
• ✅ Session lifetime tetap mengikuti SESSION_LIFETIME (120 menit default)
• ✅ API calls dari dashboard menggunakan auth.api middleware (hybrid)

API Clients (Mobile/External)

• ⚠️ IMPACT - Access token expired setelah 24 jam
• ✅ SOLUTION - Gunakan refresh token untuk dapat access token baru
• ✅ BETTER UX - Tidak perlu login ulang selama 30 hari

Existing Tokens

• ⚠️ WILL BE INVALIDATED - Semua token existing akan dihapus saat user login pertama kali setelah deploy
• ✅ AUTO MIGRATE - User akan dapat token baru dengan expiration otomatis

---

🔧 Troubleshooting

Issue: Refresh token tidak bekerja

Check:

# Verify refresh_tokens table exists
php artisan tinker
>>> App\Models\RefreshToken::count()

Solution: Run migration

php artisan migrate

Issue: Token tidak expired setelah 24 jam

Check:

php artisan tinker
>>> config('sanctum.expiration')

Solution: Clear config cache

php artisan config:clear

Issue: Anomaly detection tidak log

Check: storage/logs/laravel.log

Solution: Verify middleware registered

php artisan route:list --path=api/v1/user
# Should show middleware: auth:sanctum,token.anomaly

---
