Passkeys are emerging as a popular passwordless authentication method, supported by major tech companies like Google, Apple, and Microsoft, and are gaining traction in identity management. Auth0 users can integrate passkey authentication using Descope as their OpenID Connect (OIDC) Provider without needing to overhaul existing systems. Passkeys, which utilize device-based biometrics like fingerprints or face scans, enhance security and user experience by eliminating the need for traditional passwords and the associated risks of credential theft. The integration process involves configuring Descope within Auth0 as an Enterprise OIDC connection, allowing seamless passkey authentication while maintaining user management through Auth0. This setup supports a smooth transition for existing users and offers compatibility across multiple devices and modern browsers. By adopting passkeys, developers can offer a secure, efficient login method that aligns with contemporary authentication standards.
