@waprin How new is the ADC command? Are our users likely to be using older gcloud CLI without it?

It came out in late March. I would say most users should be updating their gcloud frequently enough that they should have it. Our official auth docs recommend it instead of gcloud auth login.

It is still in beta and it's a confusing change so I don't blame you if you want to hold off. However I asked the PM responsible for auth on the platform and he told me I should recommend the change (with apologies for the confusion). And again, sooner or later this change will be necessary since gcloud auth login will stop writing the credentials.

Maybe the last graph should add a sentence pointing to the docs for updating the gcloud CLI? Something like:

Previously, gcloud auth login was used for both use cases. If your gcloud installation does not support the new commend, please update it: see {URL HERE}.

The CLI can update itself so I just added the command to do that.

@waprin Thanks for the patch!
