#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault

##Steps

This is how to resolve the following command line error message when pushing your app to Heroku:

~/Desktop/appname git push heroku master
fatal: 'heroku' does not appear to be a git repository
fatal: Could not read from remote repository.
fatal: 'heroku' does not appear to be a git repository
Please make sure you have the correct access rights and the repository exists.

The above error message appears because there's no remote named heroku. When you do a heroku create, if the git remote doesn't already exist, Heroku automatically creates one assuming you're in a git repo.
