Passwordless Authentication
Passwordless authentication removes the password as the primary secret and replaces it with stronger authentication methods.
Definition
Passwordless authentication is an authentication model that removes the password as the primary secret and instead uses stronger, often phishing-resistant methods such as device-bound cryptographic authenticators, passkeys, biometrics combined with secure hardware, or certificate-based mechanisms. The goal is not merely user convenience, but a structural reduction in credential theft risk, password reuse, helpdesk reset costs, and phishing exposure.
Why it matters
Passwordless authentication is a major shift in enterprise IAM because it reduces dependency on shared secrets and improves phishing resistance.
The Ariovis perspective
Authentication strength should match the risk of the journey rather than impose the same friction everywhere. Ariovis looks for a balance between security, maintainability and user experience.
