Signet High-Capacity Thumbdrive Supports 2FA, Password & Secure Data Storage (Crowdfunding)

Signet HC Crowdfunding Started

The latest version of the Signet thumbdrive is the Signet HC. The HC has a number of enhanced features and a lower price point, making it an attractive alternative to other high-security flash drives.  The drive is high capacity storage, with secure storage technology, 2 Factor Authentication (2FA) token and encryption.  It also has a password manager and enhanced database features.  The company has started its crowdfunding campaign and there are several device quantity options and peripherals.

Features of the Signet HC

The Nth Dimension has announced the Signet HC recently, bringing to the forefront of its latest device, the all-in-one aspects of the drive’s capabilities. The  Signet HC is certainly positioned to be one of the top featured, encrypted password protected, and 2FA storage devices of its size. The data on the drive is encrypted, and password protected and can be accessed through cross-platform client application available on Windows, macOS, GNU/Linux, and Android.  There is no need for a software download because the client software is stored right on the device.

Other Extended Features

There is physical security for malware protection, Signet HC implements FIDO U2F and FIDO2 two-factor authentication protocols used by many websites. Again, once a compatible transaction or login occurs the device will flash, indicating a physical interaction to complete the authentication. A press of the button on the device and the 2FA is completed. There are advanced mass storage security features including

    • Read Only volumes
    • Encrypted Volumes
    • One-time-use volumes
    • Physically-secured volumes
    • Unencrypted volumes

Personal and Password Management is a development from the original Signet drive. Access is through a secure database and can be viewed in the client and utilized directly for logins at websites. Flexible data storage, encryption key storage, and processing and multi-profile support round out the features of the drive.
