FIDO Authentication

FIDO (Fast Identity Online) Authentication is an open standard designed to replace password-based logins with stronger, phishing-resistant authentication methods. Developed by the FIDO Alliance, it enables secure sign-ins using public key cryptography, where a private key is stored on the user’s device and a corresponding public key is registered with the service. Instead of relying on shared secrets like passwords, FIDO verifies identity through possession (device), biometrics, or hardware security keys.For banks, fintechs, e-commerce platforms, healthcare providers, and enterprises, FIDO Authentication reduces the risk of credential theft, phishing, and account takeover attacks while providing a seamless user experience. It supports multi-factor authentication (MFA) and passwordless workflows, making it widely adopted in high-security industries. With increasing regulatory emphasis on strong customer authentication, FIDO is emerging as a global standard for balancing convenience, compliance, and robust digital security.
