Your AWS or GCP root account has unlimited access: billing changes, account closure, unrestricted resource modification. A compromised root account doesn’t just mean a data breach—it means potential business extinction. Yet the question of how to secure it with multi-factor authentication remains surprisingly contentious: physical YubiKeys or virtual authenticator apps?

This decision matters more than most security choices because root accounts sit outside normal guardrails. You can’t delegate root account access to IAM roles, you can’t easily test disaster recovery, and mistakes are catastrophic. The traditional security playbook says “use hardware MFA”—but that advice predates the reality of distributed teams, remote-first companies, and the operational complexity of managing physical devices across continents.
