## ❗ Important Notes

1. **Password Hashing**: Semua passwords di database sudah di-hash dengan Bcrypt
2. **Authentication Guard**: Default guard adalah 'web' (session-based)
3. **User Model**: Config menggunakan UserDosen sebagai default auth model
4. **Attendance Table**: Kosong saat awal, data akan ter-populate saat user check-in/check-out
5. **Remember Token**: Diperlukan jika menggunakan "Remember Me" feature

---

## 🔧 Troubleshooting

### Login Gagal dengan Error "NIP atau password tidak sesuai"
- Pastikan NIP benar (case-sensitive)
- Pastikan password sesuai dengan yang di-hash di database
- Gunakan command `php artisan app:reset-password` untuk reset password

### "Class not found" Error
- Jalankan `php artisan config:cache && php artisan config:clear`
- Pastikan semua migrations sudah di-run: `php artisan migrate`

### Welcome Page Tidak Bisa Diakses
- Pastikan user sudah login (check session cookie)
- Pastikan middleware 'auth' aktif pada route
