The Passwordless Future: Effectiveness and Adoption in Enterprise Security Systems

Abstract. The heavy use of password-based authentication has created serious weaknesses in security systems for businesses. This has led to increasing threats from phishing, credential theft, and identity breaches. As organizations move online and adopt hybrid or remote work, they need secure, easy-to-use, and flexible authentication methods. This paper looks at how passwordless authentication systems can change how identities are managed in businesses. By examining different models, strategies to reduce threats, and user experiences, the study claims that passwordless authentication, which uses technologies like FIDO2, biometrics, and cryptographic tokens, provides better protection and efficiency than traditional credentials. The paper also offers a practical framework for implementation and a hypothetical case study to show how to adopt this approach in phases, outline technical issues, and highlight long-term benefits. Finally, the research talks about new trends, including decentralized identity and AI-based biometric systems, placing passwordless authentication as a key part of future-proof, zero-trust business security.
