The field of authentication and biometric systems is experiencing a significant shift towards more secure and user-friendly solutions. Researchers are exploring alternative methods to traditional password-based authentication, such as leveraging Web Authentication APIs for passwordless login and utilizing mobile devices for token-based authentication. Additionally, there is a growing interest in biometric authentication systems that utilize novel signals such as ear-EEG and bio-impedance sensing for head pose estimation. These innovative approaches aim to address the limitations and vulnerabilities of existing authentication methods, providing stronger security guarantees and improved usability. Noteworthy papers in this area include:

• SSH-Passkeys: Leveraging Web Authentication for Passwordless SSH, which proposes a framework for integrating WebAuthn with SSH servers, offering protection for cryptographic material and resistance to key leaks.
• An Investigation of Ear-EEG Signals for a Novel Biometric Authentication System, which explores the feasibility of biometric authentication using ear-EEG signals, demonstrating promising performance with an average accuracy of 82% in a subject identification scenario.
