Phishing-Resistant MFA
Phishing-resistant MFA is multi-factor authentication that cannot be defeated by phishing or social-engineering attacks. Unlike text-message codes or simple push approvals — which a victim can be tricked into handing to an attacker — phishing-resistant methods cryptographically bind the login to the legitimate website, so they fail safely on a fake one.
Why Standard MFA Can Still Be Phished
Attackers now run real-time phishing kits that sit between the victim and the real site, relaying credentials and one-time codes as the victim enters them. Push-approval fatigue attacks simply bombard a user until they tap “approve.” These techniques defeat SMS codes, authenticator codes, and basic push MFA — which is why those methods are no longer considered sufficient for high-value accounts.
How Phishing-Resistant MFA Works
Phishing-resistant MFA — hardware security keys and passkeys built on the FIDO2 and WebAuthn standards — uses public-key cryptography tied to the genuine website’s address. If the user lands on a look-alike phishing site, the credential simply will not work, because the cryptographic check fails. There is nothing for the user to type and nothing for an attacker to relay.
Why Phishing-Resistant MFA Matters for Investment & Professional Firms
For DFW registered investment advisers, law firms, and accounting firms, privileged accounts and accounts that can move client assets warrant the strongest available protection.
