Hardware Security Keys
Hardware security keys are physical devices that provide strong authentication for accessing systems, applications, or data, typically using public-key cryptography and standards like FIDO2/WebAuthn. They offer a more secure alternative to passwords by requiring physical possession of the key for authentication, often combined with a PIN or biometric verification. These keys are commonly used for multi-factor authentication (MFA) to protect against phishing, credential theft, and unauthorized access.
Developers should learn about and use hardware security keys when building or securing applications that require high levels of authentication security, such as in finance, healthcare, or enterprise environments. They are essential for implementing phishing-resistant MFA, complying with security standards like NIST guidelines, and protecting sensitive user accounts from attacks like credential stuffing. Use cases include securing developer accounts (e.g., GitHub, AWS), enabling passwordless login flows, and enhancing security for critical infrastructure.
