LOGIN SYSTEM

building login system

Implement a basic user login system in a Rails app
without using a high-level gem like devise. You may use gems to help you e.g. warden. You don't need to do password recovery or anything like that, just the basic "User with an existing account can login" flow.

  • Code clarity
  • Tests
  • clear Git commit messages

Don't spend more than a few hours on this code
the goal here isn't for you to fully finish the feature
(although you can if you want)
but to have a chunk of your code
to discuss at the interview.

60 to 90 minutes
