The login prompt stares back, waiting for your credentials. You don’t type a password. Instead, Hashicorp Boundary hands the job to OAuth 2.0. Authentication flows silently. Roles, policies, and tokens line up. Access is granted without exposing secrets.
Hashicorp Boundary is built to control secure access to systems and services at scale. With OAuth 2.0, it becomes a streamlined gate. Boundary uses identity providers—Okta, Auth0, Azure AD, Google Workspace—to authenticate users. The result: central identity, federated logins, and no static credentials in your infrastructure.
Configuring OAuth 2.0 in Boundary starts with an auth method. From the Boundary UI or CLI, you define an OIDC auth method that points to your provider. You set the client ID, client secret, authorization and token endpoints, scopes, and callback URLs. Boundary stores nothing except the data it needs to verify identities. OAuth handles the rest.
When a user attempts access, Boundary redirects them to the identity provider’s login page. OAuth 2.0 negotiates authorization via secure tokens. Once authenticated, Boundary applies its own policies—mapping users into roles for controlled access. This separation of authentication and authorization hardens your security model.
