TL;DR: Weak second factors can still let phishing, SIM swapping, and approval abuse defeat 2FA, according to 1Kosmos. Sensitive access paths need assurance that resists those attacks instead of relying on a second step alone.
Editorial analysis by NHI Mgmt Group, based on content published by 1Kosmos: “2FA vs MFA: Understanding the Layers of Modern Authentication”.
Key questions
Q: Why do phishing-resistant factors matter more than stronger passwords?
A: Because they change the attack model.
Q: What are the signs that MFA is failing in practice?
A: Repeated prompt approvals, rising help desk complaints about login fatigue, unexpected approvals from unusual locations, and successful phishing relays all indicate that the control is being treated as a ritual rather than a safeguard.
Q: When does basic 2FA become too weak for production access?
A: Basic 2FA becomes too weak when the account can reach sensitive data, administrative controls, remote access, or regulated systems.
Practitioner guidance
- Deprecate SMS-based 2FA Replace SMS codes with app-based authenticators or hardware-backed methods for any account that can reach sensitive data, administrative consoles, or remote access paths.
- Require phishing-resistant MFA for privileged access Make hardware-backed keys or verified identity factors mandatory for administrators, break-glass accounts, and regulated workloads that would expand blast radius if compromised.
- Implement adaptive step-up policies Use device trust, location, and behavioural context to increase challenge only when the session risk rises, rather than forcing the same prompt pattern for every login.
Bottom line: 2FA improves over passwords alone, but weak second factors such as SMS can still be bypassed by phishing, SIM swapping, and approval abuse.

Basic 2FA is a transitional control, not an end state. It improves on passwords alone, but it does not erase the trust assumptions that make phishing, SIM swapping, and push fatigue successful. The stronger the threat model and the more sensitive the system, the faster basic 2FA loses architectural relevance. Practitioners should treat it as a stepping stone, not a stable governance endpoint.
A few things that frame the scale:
- Across one million observed logins, 1 in 4 were password-based rather than SSO, 2 in 5 were not protected by MFA and 1 in 5 used a weak, breached or reused password.
A question worth separating out:
Q: Should organisations use the same authentication method for all users and use cases?
A: No, but they should use the same assurance standard where the risk is similar. Privileged access, sensitive applications, and remote access should share a phishing-resistant baseline, even if the form factor differs. Consistency matters more than one branded method, because fragmented exceptions create governance drift and a larger attack surface.
