User Authentication in Ruby on Rails

I came across a post in www.codeproject.com. It was a pretty good explanation on how to create an elaborate authentication module in a Ruby on Rails website. I decided to implement it as a part of my first semester project after discussing the idea with K, I was able to understand it and do it successfully.

I wish to record what I learnt in implementing this module, in this blog post. I will update this whenever I get time. I will also put a link to my project once I fine tune it and upload it in github.
