The official Meteor Accounts packages are stored and officially supported via the main Meteor repository where they can be found in their respective accounts-<service> folders.
If you have an issue with Meteor Accounts, you should make a reproduction and report it to Meteor Issues.
This project was an attempt to decouple Meteor accounts but is not completed and still a work-in-progress (though currently stalled). One of the goals was to decouple the view layer, which has already been done on the main Meteor repository.
