MFA Won't Save You From OAuth Consent Abuse

Multifactor authentication (MFA) alone cannot defend against OAuth consent abuse, which exploits the authorization framework to grant applications excessive permissions. Organizations need to combine MFA with OAuth governance, least-privilege scope assignment, consent monitoring, and rapid revocation capabilities.

Why it matters: Development and security teams relying solely on MFA for OAuth security face risk from compromised or malicious applications gaining broad access to user data and systems; implementing OAuth governance and scope controls provides essential defense today.
