Authentication protocols are essential for securing systems and ensuring the identity of users. Here's an overview of some common authentication protocols:

Common Authentication Protocols

  • Basic Authentication Basic Authentication is a simple method where the username and password are transmitted as plain text. This is not recommended for secure environments.

  • OAuth 2.0 OAuth 2.0 is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service.

  • OpenID Connect OpenID Connect is an identity layer on top of the OAuth 2.0 protocol. It provides an identity assertion to an application by which an end-user can prove their identity to the application.

  • SAML (Security Assertion Markup Language) SAML is an XML-based framework for exchanging authentication and authorization data between parties.

  • JWT (JSON Web Tokens) JWT is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

  • Two-Factor Authentication (2FA) Two-Factor Authentication adds an additional layer of security to your accounts by requiring two methods of authentication from independent categories of credentials.
