MFA solves a different problem
Multi-factor authentication was built to answer one question: does whoever is logging in also have access to a second factor, a phone, an authenticator app, a hardware key? That's valuable for account security. It says nothing about whether the specific instruction someone just sent is genuinely theirs, versus an account that's been compromised despite MFA being enabled.
MFA can be bypassed
SIM-swapping, where an attacker convinces a carrier to transfer a phone number to a new device, defeats SMS-based MFA directly. Phishing pages that relay a one-time code in real time defeat app-based MFA too. Neither of these is exotic; both are established, well-documented attack techniques, which means "we require MFA" isn't the airtight protection it can sound like.
The gap MFA leaves in a wire transaction
Even with MFA fully enforced, the underlying question in wire fraud is unchanged: is the party providing these instructions actually who they claim to be? MFA confirms access to a device or account. It doesn't confirm the identity of a human being on the other end of a transaction, which is precisely the thing that matters when money is about to move.
What biometric verification adds
A biometric check, matching a live face against a claimed identity, closes a different gap than MFA does. It doesn't matter whether an account was compromised, or whether a code was intercepted, if the actual person completing verification has to physically match who they claim to be. That's a check that phishing and SIM-swapping simply don't defeat. That verification, along with every other check in the process, is written to a private blockchain, so even the record of who was verified can't be quietly altered afterward.
Layered, not either-or
This isn't an argument against MFA, it's a case for adding a layer MFA was never designed to provide. Account security and identity verification solve different problems, and a wire verification process that only relies on one of them is missing the other.
- Isn't MFA already sufficient security for financial transactions?
- MFA is valuable, but it verifies access to a device or account, not the identity of the person behind a specific transaction. Those are different guarantees.
- How does biometric verification resist phishing?
- A biometric match requires the actual physical presence of the person being verified, which a phished code or intercepted SMS message can't replicate.
