Authentication is the process of verifying the identity of a user, device, or application attempting to access a system or network.
Authentication is a critical component of security that helps to protect IoT devices and networks from unauthorized access and cyber attacks. IoT authentication methods can include traditional username and password combinations, as well as more advanced methods like two-factor authentication (2FA) or multi-factor authentication (MFA), biometrics, and digital certificates.In addition to ensuring that only authorized users are granted access to IoT devices and systems, authentication also helps to prevent impersonation attacks and the use of stolen credentials. As IoT devices and networks continue to grow in complexity and scale, effective authentication mechanisms are becoming increasingly important to ensure the security and integrity of IoT systems. Additionally, the use of strong authentication mechanisms can help organizations comply with industry regulations and data protection laws.
