Consumers are increasingly targeted by cybercriminals that use various techniques in account takeover (ATO) attacks. These attacks threaten the security of their online accounts and personal data. The article details what consumers can do to prevent attacks including; W3C’s Web Authentication standard, otherwise known as WebAuthn. WebAuthn is part of a standard set of protocols called Fast Identity Online, or FIDO. Most modern mobile phones support FIDO today, along with an increasing number of tablets, laptops, and desktops. FIDO is mainstream, allowing for broad adoption in consumer-oriented use cases (i.e., Consumer Identity & Access Management, or CIAM).
