Want to know the difference between OIDC vs Saml vs Oauth? As the digital landscape continues to evolve, the need for secure and seamless authentication and authorization processes has become increasingly crucial. Three of the most prominent standards in this space are OpenID Connect (OIDC), Security Assertion Markup Language (SAML), and OAuth. Let’s explore the key differences between these protocols:
OIDC vs Saml:
OpenID Connect (OIDC) and Security Assertion Markup Language (SAML) are both authentication standards that support single sign-on (SSO), but they have some key differences:
OIDC vs Saml
What is SAML?
- Purpose:
- OIDC is primarily used for user authentication on consumer websites and mobile apps.
- SAML is more commonly used for enterprise users to sign in to multiple applications.
- Technology:
- OIDC uses JSON Web Tokens (JWTs) and RESTful HTTP endpoints.
- SAML uses XML documents and HTTP or SOAP for data transport.
- Ease of Use:
- OIDC is generally easier to implement and integrate into modern applications due to its use of more popular technologies.
- SAML can be more difficult to implement, especially for those unfamiliar with XML and XML Digital Signatures.
- Security:
- Both OIDC and SAML support strong security mechanisms, but SAML is considered a more mature standard that’s better suited for large enterprises that require a higher level of security.
- History:
- SAML is an older standard that dates back to 2005 and is still trusted by many organizations, including government entities.
- OIDC is built on the OAuth 2.0 protocol and takes into account improvements in modern web browsers.
OIDC is more suitable for consumer-facing applications, while SAML is more commonly used in enterprise environments that require a higher level of security and a more established standard.
Difference Between Saml and OIDC
SAML is older, uses XML, and is commonly used for enterprise applications. OIDC, with its JSON format, is favored for consumer websites and mobile apps. Choose the one that aligns best with your organization’s needs! Let’s explore the differences between (OIDC vs Saml) SAML (Security Access Markup Language) and OIDC (OpenID Connect):
- Data Format:
- SAML: Transmits user data in XML format.
- OIDC: Transmits user data in JSON format.
- Terminology:
- SAML:
- Refers to the application or system the user is trying to access as the Service Provider (SP).
- Calls the data it sends from the Identity Provider (IdP) to the SP an assertion.
- OIDC:
- Refers to the application or system as the Relying Party.
- Calls the data it sends Claims.
- SAML:
- Popularity:
- SAML has been around since 2005 and remains one of the most popular SSO protocols.
- OIDC is built on the OAuth 2.0 protocol and is well-suited for mobile and single-page web applications.
Similarities Between OIDC vs SAML
SAML and OIDC are both authentication protocols that enable single sign-on experiences for users. They share similarities in being highly secure standards that can be customized to protect user privacy by controlling shared attributes (claims). Additionally, both leverage a third-party identity provider to handle authentication.
OIDC vs Saml
SAML and OIDC are the key protocols used in SSO solutions because their purpose is to facilitate this trust relationship. The goal of an SSO system is to allow users to authenticate once with the IdP, and then be able to access any applications that have been configured to trust that IdP’s authentication.
OIDC vs SAML Use Cases

OIDC vs Saml
OIDC is more suitable for consumer-facing applications, SAML is more commonly used in enterprise environments, and OAuth is an authorization protocol that can be useful for mobile applications.
OIDC (OpenID Connect):
- OIDC is an authentication protocol built on top of the OAuth 2.0 authorization protocol.
- It uses JSON Web Tokens (JWTs) to standardize areas that OAuth leaves open to choice.
- OIDC is commonly used for user authentication in mobile apps and consumer-facing websites.
- It’s useful when an application needs temporary access or when all the authentication work needs to be done by the application itself.
SAML (Security Assertion Markup Language):
- SAML is an authentication protocol based on XML.
- It can exchange authentication and authorization information between multiple security domains.
- SAML is often used to help enterprise users sign in to multiple applications using a single login.
- It’s suitable for identity management because of its strong encryption capabilities, which can help keep important information secure.
OAuth:
- OAuth is an authorization protocol that can provide authorization to a protected resource, such as a set of files.
- OAuth does not authenticate the user; it only allows the user to access certain parts of an application.
- OAuth is often recommended when you need to enforce security practices for mobile applications with minimal hassles, such as when granting permission to add your Facebook contacts to your phone’s contacts.
OIDC is more suitable for consumer-facing applications, SAML is more commonly used in enterprise environments, and OAuth is an authorization protocol that can be useful for mobile applications. Understanding the strengths and use cases of each standard can help you make an informed decision when implementing authentication and authorization solutions for your organization.
Authorization Endpoint: OIDC vs Saml
The OIDC (OpenID Connect) authorization endpoint is the endpoint where users authenticate and authorize an application to access their information. It is part of the OIDC protocol, which is an identity layer on top of the OAuth 2.0 authorization framework.
The OIDC authorization endpoint is typically located at a specific URL on the identity provider’s server, such as https://example.com/authorize. When a client application wants to authenticate a user and obtain an access token, it sends the user to this endpoint with the appropriate request parameters, such as the client ID, requested scopes, and response type.
The user then authenticates at this endpoint, typically by entering their credentials. If the authentication is successful, the endpoint will redirect the user back to the client application with an authorization code or access token, which the client can then use to obtain additional user information or access protected resources.
The SAML (Security Assertion Markup Language) authorization endpoint is the endpoint where users authenticate and authorize an application to access their information. It is part of the SAML protocol, which is an XML-based framework for exchanging authentication and authorization data between security domains.
The SAML authorization endpoint is typically located at a specific URL on the identity provider’s server, such as https://example.com/saml/auth. When a client application wants to authenticate a user and obtain an access token, it sends the user to this endpoint with the appropriate request parameters, such as the service provider identifier, requested attributes, and response type.
The user then authenticates at this endpoint, typically by entering their credentials. If the authentication is successful, the endpoint will respond with a SAML assertion, which the client application can then use to obtain additional user information or access protected resources.
In summary in the context of OIDC vs Saml, the main difference between the SAML authorization endpoint and the OIDC authorization endpoint is the underlying protocol and data format used for the authentication and authorization process. SAML uses XML-based assertions, while OIDC uses JSON-based tokens.
The specific details of the OIDC authorization endpoint, such as the required request parameters and response types, are defined in the OIDC specification.
