Features That Enhance Security
Multi-Use Authentication
The immurok Auth Key extends its functionality beyond basic screen unlocking, offering a comprehensive suite of authentication features. These include:
- Authorizing sudo commands for administrative tasks.
- Generating Time-Based One-Time Passwords (TOTP) for secure logins.
- Managing API keys and securely storing SSH private keys.
- Requiring fingerprint approval for high-risk commands in AI systems.
These capabilities provide an additional layer of control and accountability, making the device suitable for both personal and professional applications.
Offline Data Storage
Sensitive data, such as TOTP secrets, API keys and SSH keys, is securely stored offline within the device. This design minimizes exposure to threats like malware, phishing and network-based attacks. Additionally, the device incorporates tamper detection technology. If tampering is detected, it automatically wipes all stored data, making sure your information remains secure even in the event of physical compromise.
