When managing your cryptocurrency with the BitBox02 hardware wallet, it's essential to differentiate between the device password and the optional passphrase. Each serves a distinct purpose in safeguarding your assets.
Device password: your primary security layer
- Purpose: The device password protects your BitBox02 from unauthorized access. Each time you connect your BitBox02, you're prompted to enter this password.
- Functionality: It encrypts the device's contents, ensuring that without the correct password, the wallet remains inaccessible.
- Setup: During the initial configuration of your BitBox02, you're prompted to create this password. It's mandatory and cannot be deactivated.
Optional passphrase: an advanced security feature
- Purpose: The optional passphrase adds an additional layer of security by creating a hidden wallet. This feature is particularly useful if your recovery words are compromised.
- Functionality: When enabled, the passphrase combines with your recovery words to generate a completely new wallet. Each unique passphrase accesses a different wallet.
-
Setup: To enable the optional passphrase:
- Open the BitBoxApp with your BitBox02 connected.
- Navigate to “Device Settings.”
- Select "Enable optional passphrase" and follow the on-screen instructions.
Note: Ensure you remember your passphrase. Losing it means losing access to the funds in the associated hidden wallet.
Key differences between device password and optional passphrase
| Aspect | Device password | Optional passphrase |
|---|---|---|
| Purpose | Protects the BitBox02 device from unauthorized access. | Creates additional hidden wallets for enhanced security. |
| Usage frequency | Required each time the device is connected. | Entered after the device password when accessing a hidden wallet. |
| Relation to wallet | Does not alter the wallet; it's solely for device access. | Alters the wallet by generating a new one based on the passphrase used. |
| Recovery | Can be reset by restoring the device with recovery words. | Cannot be recovered if forgotten; funds in the hidden wallet will be inaccessible. |
Best practices
- Secure storage: Store both your recovery words and any passphrase securely and separately.
- Complexity: Choose a strong, unique passphrase to prevent brute-force attacks.
- Caution: Only enable the optional passphrase if you're confident in managing and remembering it. Mismanagement can lead to permanent loss of funds.
Conclusion
While the device password and optional passphrase both contribute to the security of your BitBox02, they serve different functions. Understanding and appropriately utilizing each ensures robust protection for your cryptocurrency assets.
