Goth: Multi-Provider Authentication for Go

Package goth provides a simple, clean, and idiomatic way to write authentication packages for Go web applications.

Unlike other similar packages, Goth, lets you write OAuth, OAuth2, or any other protocol providers, as long as they implement the Provider and Session interfaces.

This package was inspired by https://github.com/intridea/omniauth.

Installation

$ go get github.com/markbates/goth

Examples

See the examples folder for a working application that lets users authenticate through Twitter, Facebook, Google Plus etc.

To run the example either clone the source from GitHub

$ git clone git@github.com:markbates/goth.git

or use

$ go get github.com/markbates/goth

$ cd goth/examples
$ go get -v
$ go build
$ ./examples

Now open up your browser and go to http://localhost:3000 to see the example.

To actually use the different providers, please make sure you set environment variables. Example given in the examples/main.go file

Security Notes

By default, gothic uses a CookieStore from the gorilla/sessions package to store session data.

As configured, this default store (gothic.Store) will generate cookies with Options:

&Options{
   Path:   "/",
   Domain: "",
   MaxAge: 86400 * 30,
   HttpOnly: true,
   Secure: false,
 }

To tailor these fields for your application, you can override the gothic.Store variable at startup.

The following snippet shows one way to do this:

key := ""             // Replace with your SESSION_SECRET or similar
maxAge := 86400 * 30  // 30 days
isProd := false       // Set to true when serving over https

store := sessions.NewCookieStore([]byte(key))
store.MaxAge(maxAge)
store.Options.Path = "/"
store.Options.HttpOnly = true   // HttpOnly should always be enabled
store.Options.Secure = isProd

gothic.Store = store
