Enable authenticator manually

Currently my client authenticates request only on case of 401 response:

this.client.authenticator(new okhttp3.Authenticator() {

      public Request authenticate(Route route, Response response) throws IOException {
      String credentials = authenticator.getCredentials();
      if (credentials.equals(response.request().header("Authorization"))) {
            throw new TraversonException(401, "Unauthorized", response.request().url().toString());
      } else {
            defaultHeader("Authorization", credentials);

            Request.Builder newRequest = response.request().newBuilder()
                                .headers(Headers.of(defaultHeaders));

             return newRequest.build();
         }
});

But I'd like to change this behavior and be able to call it either manually or auto per first call? Is it possible somehow?

If the authentication is predictably required and not related to a proxy, then the solution is to implement an Interceptor instead of Authenticator.

OkHttpClient.Builder clientBuilder = ...;
clientBuilder.networkInterceptors().add(0, myInterceptor);
client = clientBuilder.build();

Example Interceptor https://github.com/yschimke/oksocial/blob/48e0ca53b85e608443eab614829cb0361c79aa47/src/main/java/com/baulsupp/oksocial/uber/UberAuthInterceptor.java

n.b. There is discussion around possible support for this usecase in https://github.com/square/okhttp/pull/2458. One issue with current Authenticator API is that it assumes a Response from the failed (401) request.
