OpenID Connect (OIDC)

OIDC (OpenID Connect) is a standard for secure authentication that enables the exchange of authentication and authorization data between identity providers (IdPs) and client applications. It is an open, standards-based protocol for secure, single sign-on (SSO) authentication that is built on top of OAuth 2.0.

OIDC provides a secure and standardized way for users to log into client applications using their existing identity provider accounts. The user logs into the IdP, which then generates a signed token containing the user's identity information, which is then passed to the client application. The client application can then use this token to authenticate the user and provide access to protected resources.

Pros:

1. Single Sign-On (SSO): OIDC allows users to log into multiple websites and applications with a single set of credentials, providing a convenient and user-friendly SSO experience.

2. User Experience: OIDC enables a seamless user experience, as users do not need to remember multiple sets of login credentials or manually enter their information each time they log in.

3. Interoperability: OIDC is based on open standards and is supported by many organizations and service providers, making it easier for applications and services to integrate with one another.

4. Increased Security: OIDC provides a secure way to authenticate users, reducing the risk of account takeovers, phishing attacks, and other types of fraud.

Cons:

1. Complexity: Implementing OIDC can be complex, particularly for organizations that need to integrate with multiple identity providers and service providers. Organizations are encouraged to be careful when implementing OIDC.

2. Reliance on Third-Party Identity Providers: OIDC relies on third-party identity providers to manage user credentials and authentication, which can introduce security risks and operational complexities.

3. Increased Dependency on Network Connectivity: OIDC requires a reliable and secure network connection, which can limit its use in low-bandwidth or offline environments.

4. Potential for Privacy Concerns: OIDC requires users to share personal information with identity providers and service providers, which can raise privacy and security concerns.

Pomerium enables OIDC for any application.
