One-Time Password Generation and Two-Factor Authentication Using Molecules and Light.

Area of Science:

• Molecular chemistry
• Cybersecurity
• Authentication technologies

Background:

• One-time passwords (OTP) enhance security by providing single-use credentials.
• Two-factor authentication (2FA) adds a layer of security beyond traditional passwords.
• Current OTP generation methods often rely on electronic devices.

Purpose of the Study:

• To demonstrate the first molecular approach for generating one-time passwords (OTP).
• To develop a molecular system for two-factor authentication (2FA).
• To leverage photochromic molecular properties for secure authentication.

Main Methods:

• Utilized a photochromic molecular triad system.
• Explored the dependence of fluorescence on the initial isomeric state of the triad.
• Investigated optical inputs for OTP generation and authentication.

Main Results:

• Successfully demonstrated OTP generation using a molecular system.
• Showcased the potential for 2FA through molecular state manipulation.
• Confirmed that optical input requirements vary based on the molecular triad's isomeric state.

Conclusions:

• Molecular systems can be engineered for advanced security applications like OTP generation.
• Photochromic molecular triads offer a novel platform for developing secure authentication methods.
• This work presents a paradigm shift towards molecular-based cybersecurity solutions.
