Why Legacy MFA doesn’t work
Passwords are highly vulnerable
Passwords are easy to create and steal. Stolen credentials allow malicious actors to impersonate a compromised user, but can also be used to gain additional credentials and information.
SMS and other mobile MFA is also susceptible to phishing
SMS or mobile authentication is vulnerable to phishing. Phishing-resistant MFA is the modern and effective approach to keeping you and your data protected.
Modern MFA delivers
Stop phishing and prevent ransomware with modern MFA based on modern FIDO/WebAuthn authentication protocols.
