The surest way to protect your customer’s data and your intellectual property from cybersecurity breaches is with multi-factor authentication. As hackers develop more sophisticated social engineering techniques, phishing-resistant MFA in particular is becoming a crucial investment.
of cybersecurity breaches are due to compromised credentials, costing on average $4.37M per breach.

What types of MFA does Stytch support?

We support both conventional MFA (SMS one-time passcodes, email verification, and TOTP authenticator apps like Google Authenticator) as well as phishing-resistant MFA such as those built upon WebAuthn (device-based biometrics and hardware keys like YubiKey)

What exactly does phishing-resistant MFA mean? I thought MFA was phishing-resistant…

You’re not alone! But unfortunately, certain MFA factors like SMS passcodes can still be vulnerable to certain kinds of attacks, mostly based on hackers’ ability to prey on peoples’ emotions. The best way to prevent this is through auth factors that leverage biometrics – a type of credential that’s much more unique and harder to steal given its device-tied nature. For a deeper dive on what this can look like, check out our blog on unphishable MFA, or our WebAuthn or Native Mobile Biometrics products.

If I am interested in going passwordless, do I still need something like MFA?

While a company’s auth flow should always be tailored based on their specific user needs and data sensitivity, we generally recommend using MFA for situations where higher assurance is required, even if you’ve done away with passwords. Because of the phishability of many different auth methods (not just passwords), the best way you can secure your users and company is by requiring at least two authentication factors.
