How to Implement OAuth2 Flow in Go

Use the GOAUTH environment variable to configure authentication commands for the go command.

export GOAUTH="git /path/to/git/repo"
go get example.com/private/module

The go command executes the specified command (e.g., git credential fill) to retrieve credentials and attaches them to HTTP requests for module downloads.

OAuth2 Flow in Go implementation uses a helper program to automatically provide login credentials when downloading code, acting like a keychain so you never have to type your password again.
