MFA reduces account takeover by requiring another proof of identity, limiting damage from stolen passwords; protect fallback and recovery paths too.

Background for this topic.
MFA requires a user to prove identity with at least two different factor types: something they know, have, or are. It limits account takeover when a password is exposed, but protection depends on the factors and their implementation; two passwords are not independent factors, and a one-time code delivered by SMS is generally weaker than a phishing-resistant credential.
Attackers may steal or relay one-time codes through phishing, trigger repeated push prompts to induce approval, exploit weak enrollment or account-recovery processes, or hijack an authenticated session after MFA succeeds. Prefer phishing-resistant methods such as FIDO2/WebAuthn security keys or platform credentials for sensitive access, protect enrollment and recovery as strongly as login, restrict weaker fallbacks, and monitor unusual authentication activity. MFA reduces risk but does not replace endpoint, session, or privileged-access controls.
Using WebAuthn, physical keys, and biometrics, organizations can adopt more advanced passwordless MFA and true passwordless systems. (Part 2 of 2)
We as industry leaders should be building on what individual platforms like GitHub are doing in two critical ways: demanding third parties improve security and creating more interoperable architectures.
While there's an immediate need to improve MFA adoption, it's also critical to move to more advanced and secure passwordless frameworks, including biometrics. (Part 1 of 2)
