Learners will receive a Certificate of Completion from Uplatz, validating their expertise in Passkeys and WebAuthn. This certification demonstrates readiness for roles in application security, identity management, and authentication engineering.

Passkeys and WebAuthn expertise prepares learners for roles such as:

• Application Security Engineer

• Identity & Access Management Specialist

• Full-Stack Developer (with security focus)

• Cybersecurity Engineer

• Enterprise Architect (IAM & SSO)

With global adoption by Apple, Google, and Microsoft, passwordless authentication is the future of login systems, making this a highly in-demand skill.

1. What is WebAuthn?
   A W3C standard for passwordless authentication using public-key cryptography.

2. What are Passkeys?
   Cross-device credentials that allow passwordless login managed by platforms like Apple and Google.

3. How does WebAuthn improve security?
   By replacing passwords with public-key cryptography, resistant to phishing and replay attacks.

4. What role does FIDO2 play?
   FIDO2 combines WebAuthn (web API) and CTAP (authenticator protocol) for strong authentication.

5. How do Passkeys sync across devices?
   They use cloud keychains (iCloud, Google Password Manager, etc.) for secure synchronization.

6. What’s the difference between authentication and authorization?

• Authentication → verifying identity.

• Authorization → verifying access rights.

7. What are common use cases of WebAuthn?
   Passwordless login, MFA, and enterprise identity solutions.

8. Which platforms support Passkeys?
   Apple (iOS, macOS), Google (Android, Chrome), Microsoft (Windows, Edge).

9. What are challenges with Passkey adoption?
   Cross-device compatibility, user education, and legacy system integration.

10. Where is WebAuthn commonly used today?
    In tech, finance, e-commerce, and SaaS platforms requiring strong security.
