What is it?

Devise is an authentication library for Ruby on Rails. It is built on Warden, a Rack-based authentication framework, and ships as a Rails engine that provides the controllers, views and routes needed for a complete sign-in system.

Functionality is split into modules that you enable per model, so you only include what you need. Available modules cover database-backed password login, OmniAuth social login, email confirmation, password recovery, user registration, remember-me cookies, activity tracking, session timeouts, validations, and locking accounts after repeated failed sign-ins. Multiple models, such as User and Admin, can be signed in at the same time.

Devise supports ActiveRecord by default and Mongoid as an alternative ORM. Its generators install a configuration initializer and create the model and routes, and helpers like authenticate_user! and current_user are available in controllers and views.

Key features

  • 01Modular authentication features you enable per model.
  • 02Database-backed password login with HTTP Basic Authentication support.
  • 03OmniAuth integration for third-party sign-in providers.
  • 04Email confirmation, password recovery and account unlock flows.
  • 05Multiple user models signed in at the same time.
  • 06Customizable controllers, views and strong parameter sanitization.

Use cases

  • Adding sign-up and sign-in to a new or existing Rails application.
  • Separating admin and end-user logins with different models.
  • Adding social login alongside email and password accounts.
  • Protecting API endpoints with HTTP Basic authentication in Rails API mode.

Quick start

  1. 1

    Add Devise to your Rails Gemfile

    bundle add devise
  2. 2

    Run the Devise install generator

    rails generate devise:install
  3. 3

    Generate a user model with Devise modules

    rails generate devise MODEL
  4. 4

    Run the database migrations

    rails db:migrate

Things to know

  • Requires a solid understanding of Rails; the README advises beginners to learn authentication from scratch first.
  • Targets Rails 7 onwards for version 5, so older Rails apps need an older Devise release.
