Authentication Protocols
Authentication protocols are standardized methods and rules that define how entities (such as users, devices, or applications) verify their identity in a secure manner. They establish the process for exchanging credentials, such as passwords, tokens, or certificates, to grant access to systems, networks, or resources. These protocols are fundamental to cybersecurity, ensuring that only authorized parties can interact with protected data or services.
Developers should learn authentication protocols to implement secure access control in applications, APIs, and networks, preventing unauthorized breaches and data theft. They are essential for use cases like user login systems, single sign-on (SSO) in enterprise environments, and securing API endpoints in web and mobile apps. Understanding protocols like OAuth 2.0 or SAML helps integrate with third-party services and comply with security standards.
