On the one hand I'd say, yes build your own simple authentication system
to learn how it all works. However, if you are thinking this is going to
be easier to create than implementing OmniAuth I really think you'll be
disappointed.

OmniAuth is the easiest authentication system I've ever worked with.

If you want excellent, and detailed, help on how to set it up I'd highly
recommend Ryan Bates' screencasts on the subject:

http://railscasts.com/episodes/304-omniauth-identity?autoplay=true

Can OmniAuth be used for simple authentication except of 3rd party system? For example, can I implement basic signup/logging in functionality (with the users saved in my database) with OmniAuth? I want to have login w/ facebook,twitter etc but also I want to give users that don't have an account on these sites to be able to signup on my site. I'm almost sure that OmniAuth is capable of doing that but just to be sure...

Thing is, I would like to write an authentication system (basically, I already did from the railstutorial.org site) just for practicing, and maybe later I will refactor it to use OmniAuth. Isn't that a good idea?
