MFA

If each application were allowed to define its own token issuance rules or MFA requirements, the attack surface would grow linearly with the number of applications, and auditing would become difficult.

Authentication protocol configuration (such as OAuth client credentials, redirect URI whitelists, session and token validity periods, and multi-factor authentication policies) is usually bound at the environment level because it directly relates to the cross-application identity trust boundary.

Chuvakin believes the core argument is not "do basic controls" but "comprehensively verify that basic controls are truly everywhere," using AI or agents to continuously assess configuration management and MFA coverage in every corner.

Multi-factor authentication (MFA) requires users to provide two or more credentials of different natures, typically combining something you know, something you have, and something you are.

In the onboarding scenario, MFA binding should be completed before the first login, and a common practice is to generate temporary credentials at the account creation stage and force MFA registration and password change at first login.

Attacks against real-time phishing proxies (such as Evilginx) can intercept session tokens, so MFA is not a panacea.

Party staff often work remotely using personal devices, and the coverage and enforcement of MFA deployment are often weak points.

Multi-factor authentication (MFA), device binding and federated login through an organizational identity provider (IdP) can be layered on top of RBAC, making it technically difficult to use an account outside its originating organizational environment.

PayPal supports enabling MFA (multi-factor authentication) via SMS, an authenticator app, or a security key.

MFA splits identity verification into a combination of at least two categories of credentials: something you know (password), something you have (phone, hardware key), and something you are (fingerprint, facial recognition).

Security experts generally recommend prioritizing authenticator apps or hardware keys, because SMS verification codes may be subject to SIM-swap attacks.

Traditional MFA based on TOTP codes or push notifications can be bypassed when attackers set up reverse-proxy phishing pages to forward codes in real time or induce users to approve.

The proposed rule would convert multi-factor authentication and encryption from addressable to required controls.

If service accounts or app registrations with Graph API access lack MFA protection, attackers can programmatically read or modify tenant data at scale after credential leakage.

If MFA is only recommended rather than enforced, attackers only need to steal a password to bypass the verification step.

Multi-Factor Authentication (MFA) is one of the core lines of defense in the Microsoft 365 security framework, requiring users to verify their identity through a second method beyond a password.

The Agent proactively distinguishes between two different security states: 'no MFA error' and 'MFA was never enforced'.

Multi-factor authentication cannot block Device Code phishing attacks because the victim actively completes authentication within a legitimate flow.

JP believes that in an era of AI acceleration, the first step for security leaders should be to solidify the fundamentals, including CVE patch management, endpoint protection, MFA covering all identity infrastructure, strong network segmentation, and robust security operations procedures

SMS verification codes are relatively weak in security due to the risk of SIM card hijacking, and authenticator apps or hardware keys should be preferred
