Your application assumes the identity of the service account to call Google APIs, so that the users aren't directly involved.
Service account credentials are used to temporarily assume the identity of the service account. Supported credential types include OAuth 2.0 access tokens, OpenID Connect ID tokens, self-signed JSON Web Tokens (JWTs), and more.
