Pre-build a Secure Authentication Layer with Authentication Zero for Ruby on Rails
Authentication is a critical element of any web application. The Ruby on Rails ecosystem has no shortage of solutions for this topic, as no authentication layer has been backed into the framework yet. Devise is a crowd favorite. Although it has ended up as the de-facto standard and sports many built-in features and great plugins (such as integrations with NoSQL databases, encryption, roles, and UID support), it works as a separate entity from your application.
