When it comes to authentication and authorization, there are two main protocols that are often used: SAML 2.0 and OIDC. Both of these protocols have their own advantages and disadvantages, so it's important to understand the difference between them in order to choose the best option for your needs.
SAML 2.0 is an XML-based standard for exchanging authentication and authorization data between parties. It is often used by enterprises as a way to federate identity across multiple systems and platforms. One of the main advantages of SAML 2.0 is that it is relatively easy to implement and deploy. Additionally, SAML 2.0 assertions are signed, which adds an extra layer of security.
