Password Security and Passwordless Authentication

Password Security and Passwordless Authentication is a practical Cybersecurity course for professionals who need to protect accounts, reduce credential-based attacks, and modernize authentication systems. Students will learn how passwords fail, how to harden password-based login, and how to plan a secure transition toward MFA, passkeys, and passwordless authentication.

Build Stronger Identity Defenses With Password Security And Passwordless Authentication

• Learn how attackers exploit weak passwords, reuse, credential stuffing, brute force, and password spraying.
• Apply secure implementation practices for password storage, reset flows, account recovery, and session protection.
• Compare MFA, phishing-resistant authentication, FIDO2, WebAuthn, CTAP, passkeys, and hardware security keys.
• Create a practical roadmap to Build stronger identity defenses with modern password practices, MFA, passkeys, and risk-aware authentication design.

This course teaches the Cybersecurity principles, technologies, and governance practices behind Password Security and Passwordless Authentication.

Students begin with the foundations of password security, including why authentication fails, how the modern threat landscape has changed, and why human behavior must be considered when designing effective policies. The course explains password reuse, weak credential habits, and policy choices that can either reduce risk or push users toward unsafe workarounds.

The secure implementation section covers the technical controls that make password systems more resilient. Students will study hashing, salts, peppers, work factors, brute force defenses, password spraying protections, breached password detection, secure reset processes, account recovery, and session security after login. These lessons help learners connect Cybersecurity theory to real-world authentication architecture.

The course then moves beyond passwords into MFA and passwordless authentication. Students will learn the strengths and tradeoffs of different MFA models, the principles of phishing-resistant authentication, and the role of public key cryptography in modern login systems. Lessons on FIDO2, WebAuthn, CTAP, passkeys, platform authenticators, and hardware security keys provide a clear technical foundation for Password Security and Passwordless Authentication strategy.

Finally, students examine adoption, governance, and long-term program maturity. They will learn how to design user-friendly passwordless flows, avoid weak account recovery patterns, migrate from passwords to passwordless authentication, measure authentication risk, and build a practical roadmap. By the end of the course, students will be able to evaluate authentication risks, improve credential hygiene, and design stronger identity defenses for modern Cybersecurity environments.
