1. Welcome

Thank you for choosing Blentity (also known as SAMURAI Key in Japan). Blentity is designed to provide high-strength, comprehensive protection for personal data, whether it's data stored on your computer, offline data on USB drives, or securing your account logins for frequently used services. Blentity ensures thorough protection in all cases.

Hardware-level encryption and key protection for data security

Traditional encryption software often stores encryption keys in unsecured environments, making all encrypted data vulnerable if the key is compromised, rendering encryption ineffective. Blentity, however, uses a CCEAL5+ high-standard security chip specifically designed to protect your encryption keys. This ensures that even in the face of physical tampering or side-channel attacks, your keys remain secure, keeping your data safe at all times.

Loss of hardware is no longer a threat

To address concerns over the misuse or loss of physical keys, Blentity employs a PIN protection mechanism. After 8 consecutive incorrect PIN entries, the device will automatically lock, preventing brute-force attacks. Additionally, with the mnemonic recovery mechanism, you can easily restore your encrypted data on any Blentity device, ensuring that your data is never lost.

Enhance login security and user experience across everyday services

Blentity can also serve as a physical security key for two-factor authentication, supporting hundreds of websites such as Google, Microsoft, Facebook, Dropbox, X (formerly Twitter), and Github (with a limit of 25 websites per key). This reduces the risks of password leaks from social engineering or phishing attacks. For websites that support passwordless protocols, Blentity also provides a seamless password-free login experience.

This document provides detailed usage instructions for the product. Before using Blentity, please read this document (please check for the latest version at https://wisecure-tech.jp/samurai_key/support) and the Terms of Use thoroughly to ensure proper and safe usage.

Appendix A ：FAQ

Q: How Does Blentity Protects My Files?

Blentity provides secure encrypted storage space and file encryption functionality through built-in hardware encryption technology. Its embedded CCEAL5+ security chip specifically protects encryption keys, avoiding storing keys in insecure computers as with software encryption. Even if subjected to physical intrusion or side-channel attacks, the chip can still effectively defend against them, ensuring the safety of your files

Q: How Does Blentity Protects My Account?

Blentity uses FIDO security key technology, ensuring through asymmetric encryption that only those possessing the hardware key can authenticate their identity. Even if the password is leaked, attackers cannot log into your account, effectively preventing phishing attacks and password theft, providing the highest level of security protection for your account.

Q：What Are the Risks If I Lost My Blentity?

Blentity uses a PIN code protection mechanism, and after 8 consecutive incorrect PIN entries, the device will automatically lock to prevent brute force attacks. You don't need to worry about others misusing your device. Additionally, Blentity provides a recovery phrase mechanism, allowing you to easily restore your data on any Blentity device, ensuring that your data won't be lost. Please be sure to store your recovery phrase securely and regularly back up your encrypted data.

Q: If the Device Is Lost, Is There a Way to Recover My Encrypted Files Stored on Blentity?

Yes, as long as you've previously used the backup function to export encrypted files, you can use that device's recovery phrase to import and restore your encrypted files on another Blentity device."

Q: If the Device Is Lost, Is There a Way to Decrypt My Encrypted Files on the Computer?

Yes, you can use that device's recovery phrase to restore your keys on another Blentity device. You can then use that Blentity to decrypt the originally encrypted files.

Q: If the Device Is Lost, Is There Still a Way to Log Into My Bound Services?

It depends on the support status of the services. Services that support FIDO usually provide their own account recovery processes. For example, some services may allow you to log back into your account using a backup security key or other identity verification processes. Please refer to the official instructions of the services you have bound to understand the specific account recovery steps.

Q: Can I change the PIN?

Yes, you can change the PIN in [settings > change PIN] without affecting stored data. 

Q: What If the PIN Gets Locked?

If an incorrect PIN is entered 8 times, or if the PIN is changed using a management tool not specific to this product, the PIN will automatically lock. At this time, the status LED will show a solid red light. Please open Blentity Manager and use the recovery phrase to unlock and reset the PIN.

Q: What should I do if I forget my PIN?

If you forget the PIN, you can unlock it using the 12-word Passphrase generated during initialization. If the Passphrase is also lost, data loss will result, so it's very important to back up data regularly and store the Passphrase securely.

Q: In What Situations Would the Recovery Phrase Be Used?

1. Unlocking a Locked PIN

   When the number of incorrect PIN entries exceeds the limit, or when the PIN is changed using a third-party tool other than Blentity Manager, the PIN will be locked. In this case, you need to enter this recovery phrase in Blentity Manager to unlock and reset the PIN.

2. Restoring Keys and Backup Files

   If you lose your device, you can use this recovery phrase to restore your device on a new one. This feature allows you to easily recover your encrypted backup files and File Encryptor encryption keys on other devices.

Q: What Should I Do If I Forget the Recovery Phrase?

Losing the recovery phrase will result in the inability to restore backup data in the future. Therefore, please be sure to keep the recovery phrase in a safe place. If you forget or lose the recovery phrase, it is strongly recommended that you first back up your data, then restore factory settings to re-establish and save a new recovery phrase. This prevents a situation where you can't unlock the device if the PIN gets locked, which would force a factory reset and result in data deletion."

Q: Does the Blentity Used for Data Restoration Have to Be Brand New?"

You can restore your encrypted backup files and related disk volume settings on any Blentity device using the recovery phrase. However, please note that the Blentity will first be reset to factory settings, and its internal data will be cleared. Be sure to back up any important data separately. Additionally, authentication services previously bound to that Blentity will no longer be accessible and will need to be re-bound. Therefore, it is recommended to perform the restoration on a new Blentity

Q: Is mobile device support, Windows Server, or Linux OS available?

These operating systems are not within our support range. If you use this product with these systems, you do so at your own risk. For supported operating systems and browsers, please refer to "Appendix B：Specifications and Supported Environments"

Q: Is software installation required?

The full-featured management tool must be installed for initialization. After initialization, the secure partition can be accessed through the Blentity Manager Lite. The product can be used on computers where the tool is not installed.

Q: Why is the number set different from the number displayed?

The disk space set may be "larger" than the space displayed on the security partition. This is because 1GB equals 1024MB, and if your set value is not divisible by 1024, this remainder will not be accounted for during the setting but will eventually be allocated to the secure partition. Therefore, the secure partition will be larger than the set value after configuration.

Q: Is it a concern that Blentity is categorized as Passkeys in certain browsers when utilized as a sign-in method for a Google account?

When registering Blentity on Edge and Chrome, it is identified as Passkeys, while on Firefox, it is recognized as a FIDO2 security key. However, you can successfully sign in regardless of the browser used for registration. User experience remains consistent across all platforms.
