Attackers have learned how to evade traditional MFA, SSO, and Identity and Access Management (IAM). So we redefined the category to include end-to-end phishing resistance. This means you can offer your clients a level of protection that other solutions simply can’t match.

Same assurance as FIDO2.

How Duo locks phishers out

Proximity verification
