  * An authentication mechanism that verifies the OIDC token.

  * <p>Currently, two flavors are supported: one that checks for the OIDC token as a regular bearer
- * token, and another that checks for the OIDC token passed by IAP. In both cases, the {@link
- * AuthResult} with the highest {@link AuthLevel} possible is returned. So, if the email address for
- * which the token is minted exists both as a {@link User} and as a service account, the returned
- * {@link AuthResult} is at {@link AuthLevel#USER}.
