Basic bcrypt auth isn't that hard to learn for a Go net/http web app. Its true, but online forums are littered with desparate cries for a django-allauth equivalent in the Go ecosystem, which doesn't exist (in a way that is trivial to incorporate). These cries either come from beginners, or from time conscious individuals uninterested in reinventing wheels. Both are valid.

I made the decision to implement auth fitting this description. By creating a public package, I can import future fixes into my disjoint projects, open the global community to make security suggestions, and help someone in the future get started more quickly.
