--- description: "IODD Admin Manager is a specialized utility for managing multi-user passwords, disk permissions, and hardware encryption settings for IODD ST400 and MINI PRO devices." --- # IODD Admin Manager The **IODD Admin Manager** is a specialized Windows application and management framework designed to control the robust AES256 hardware encryption features of IODD devices. It allows administrators to manage encryption settings, user permissions, and device locking/unlocking directly. ## 📌 Supported Models * **IODD ST400** * **IODD MINI PRO** *(Note: ST300 does not support hardware encryption, and 2541 encryption formats are not compatible with ST400/LK100 series.)* ## 🚀 Key Features ### 1. Multi-User Management & Permissions Administrators can configure up to 4 individual user profiles, each with distinct access rights to the encrypted drive: * **Read Only**: The user can access files but cannot write, modify, or delete data on the drive. * **User Change**: Permits the user to change their own password. * **User Delete**: Allows the user to delete their own account from the device. ### 2. Administrator & User Password Structure The IODD login system uses a specific prefix structure to differentiate between the administrator and general users (Max password length is 38 digits): * **Admin Login**: `0` + `[Admin Password]` * **User Login**: `[User ID (1~4)]` + `[User Password]` ### 3. Advanced Encryption & Security * **Full Disk Encryption (FDE)**: Ensures the entire disk is protected on a hardware level. * **Random Keypad**: The number positions change every time the screen is activated to prevent fingerprint tracing. * **2nd Password Support**: Serves as the ultimate administrator key used during encryption initialization or when moving an encrypted disk to another enclosure. * **Keep 2 Min. PW**: Keeps the drive unlocked for 2 minutes after disconnection. ### 4. Preset Management & Reset * **Preset Management**: Save and manage all configurations as presets for easy and quick application across devices. * **Password Reset**: Includes a feature to completely reset passwords. ## ⚠️ Important Warnings * **Data Initialization**: Enabling, disabling, or resetting the encryption password will **completely initialize (erase) all data** on the disk. Always back up critical data first! * **No Third-Party Encryption**: Do not use IODD hardware encryption simultaneously with software solutions like BitLocker or VeraCrypt, as it may cause data corruption.
