Multi-Factor Authentication

MFA adds another verification factor beyond a password. It reduces the impact of a stolen password.

Why it matters

A second factor makes account takeover harder when a password is exposed.

How it works

Password/credential → additional factor → identity is authenticated → permitted actions are evaluated.

Real-world example: Use MFA on the root identity and other privileged access according to your security policy.

Core Concept

MFA combines something you know with something you have or another approved factor.

Enable MFA for the root user and privileged identities.

Real-world example

Use a realistic cloud workload and focus on the responsibility of this AWS service.

User → AWS service → application → data / response

Choose the service that matches the responsibility instead of forcing every workload into one resource.

# Conceptual workflow aws-service --resource example # Verify configuration → test → monitor → clean up
Practice tip: Build the smallest possible lab, verify the result, then remove resources you no longer need.
