Aikotoba

Aikotoba meaning password in Japanese.

Aikotoba is a Rails engine that makes it easy to implement simple email and password authentication.

Motivation

  • Simple implementation using the Rails engine.
  • Modern hashing algorithm.
  • Separate the authentication logic from User.
  • Implementation for multiple DB.
  • Encrypting tokens using Active Record Encryption.

Features

  • Authenticatable : Authenticate account using email and password.
  • Registrable(optional) : Register an account using your email address and password.
  • Confirmable(optional) : After registration, send an email with a token to confirm account.
  • Lockable(optional) : Lock account if make a mistake with password more than a certain number of times.
  • Recoverable(optional) : Recover account by resetting password.

Installation

Add this line to your application's Gemfile:

gem 'aikotoba'

Usage

Getting Start

Aikotoba use Aikotoba::Account for authentication. Add it to the migration for Aikotoba::Account.

$ bin/rails aikotoba:install:migrations

Mount Aikotoba::Engine your application.

Rails.application.routes.draw do
  mount Aikotoba::Engine => "/"
end

Aikotoba enabled routes for registration(/sign_up) and authentication(/sign_in).

include Aikotoba::Authenticatable to the controller(ex. ApplicationController) use authentication.

class ApplicationController < ActionController::Base
  include Aikotoba::Authenticatable

  # NOTE: You can implement the get authenticated account process as follows.
  alias_method :current_account, :aikotoba_current_account
  helper_method :current_account

  # NOTE: You can implement the authorization process as follows
  def authenticate_account!
    return if current_account
    redirect_to aikotoba.new_session_path, flash: {alert: "Oops. You need to Signed up or Signed in." }
  end
end

Features

Authenticatable

Authenticate an account using email and password.

HTTP Verb Path Overview
GET /sign_in Display sign in page.
POST /sign_in Create a login session by authenticating.
DELETE /sign_out Clear aikotoba login session.

Aikotoba enable helper methods for authentication. The method name can be changed by alias_method.

  • aikotoba_current_account : Returns the logged in instance of Aikotoba::Account.

Registrable

To enable it, set Aikotoba.registerable to true. (It is enabled by default.)

Aikotoba.registerable = true

Register an account using email and password.

HTTP Verb Path Overview
GET /sign_up Display sign up page.
POST /sign_up Create an account.

The password is stored as a hash in Argon2.

Confirmable

To enable it, set Aikotoba.confirmable to true.

Aikotoba.confirmable = true

Aikotoba enable routes for confirmation account. Also, when account registers, a confirmation email is sent to the email address. Only accounts that are confirmed will be authenticated.

HTTP Verb Path Overview
GET /confirm Display page for create confirm token.
POST /confirm Create a confirm token to account.
GET /confirm/:token Confirm account by token.

Lockable

To enable it, set Aikotoba.lockable to true.

Aikotoba.lockable = true

Aikotoba enables a route to unlock an account. Also, if the authentication fails a certain number of times, the account will be locked. Only accounts that are not locked will be authenticated.

HTTP Verb Path Overview
GET /unlock Display page for create unlock token.
POST /unlock Create a unlock token to account.
GET /unlock/:token Unlock account by token.

Recoverable

To enable it, set Aikotoba.recoverable to true.

Aikotoba.recoverable = true

Aikotoba enables a route to recover an account by password reset.

HTTP Verb Path Overview
GET /recover Display page for create recover token.
POST /recover Create a recover token to account.
GET /recover/:token Display page for recover account by password reset.
PATCH /recover/:token Recover account by password reset.

Configuration

The following configuration parameters are supported. You can override it. (ex. initializers/aikotoba.rb)

require 'aikotoba'

Aikotoba.parent_controller = "ApplicationController"
Aikotoba.parent_mailer = "ActionMailer::Base"
Aikotoba.mailer_sender = "from@example.com"
Aikotoba.email_format = /\A[^\s]+@[^\s]+\z/
Aikotoba.password_pepper = "aikotoba-default-pepper"
Aikotoba.password_length_range = 8..100
Aikotoba.sign_in_path = "/sign_in"
Aikotoba.sign_out_path = "/sign_out"
Aikotoba.after_sign_in_path = "/"
Aikotoba.after_sign_out_path = "/sign_in"

# for registerable
Aikotoba.registerable = true
Aikotoba.sign_up_path = "/sign_up"

# for confirmable
Aikotoba.confirmable = false
Aikotoba.confirm_path = "/confirm"
Aikotoba.confirmation_token_expiry = 1.day

# for lockable
Aikotoba.lockable = false
Aikotoba.unlock_path = "/unlock"
Aikotoba.max_failed_attempts = 10
Aikotoba.unlock_token_expiry = 1.day

# for Recoverable
Aikotoba.recoverable = false
Aikotoba.recover_path = "/recover"
Aikotoba.recovery_token_expiry = 4.hours

Tips

Customize Message

All Messages are managed by i18n and can be freely overridden.

Manually create an Aikotoba::Account for authentication.

By running the following script, you can hash and store passwords.

Aikotoba::Account.create!(email: "sample@example.com", password: "password")
Aikotoba::Account.authenticate_by(attributes: {email: "sample@example.com", password: "password"})
# => created account instance.

Create other model with Aikotoba::Account.

You can override Aikotoba::AccountsController#after_create_account_process to create the other models together.

require 'aikotoba'

Rails.application.config.to_prepare do
  Aikotoba::AccountsController.class_eval do
    def after_create_account_process
      profile = Profile.new(nickname: "foo")
      profile.save!
      @account.update!(authenticate_target: profile)
    end
  end
end

class Profile < ApplicationRecord
  has_one :account, class_name: 'Aikotoba::Account', as: :authenticate_target
end

current_account.profile #=> Profile instance
profile.account #=> Aikotoba::Account instance

Do something on before, after, failure.

Controllers provides methods to execute the overridden process.

For example, if you want to record an error log when the account creation fails, you can do the following.

require 'aikotoba'

Rails.application.config.to_prepare do
  Aikotoba::AccountsController.class_eval do
    def failed_create_account_process(e)
      logger.error(e)
    end
  end
end

Using encrypted token

Tokens can be encrypted using Active Record Encryption, introduced in Active Record 7 and later. To use it, enable Aikotoba.encipted_token in the initializer.

Aikotoba.encypted_token = true

How to identify the controller provided.

The controller provided by Aikotoba is designed to inherit from Aikotoba::ApplicationController.

Therefore, when implementing authorization based on login status, you can disable only the controllers provided by Aikotoba as follows.

class ApplicationController < ApplicationController
  include Aikotoba::Authenticatable

  alias_method :current_account, :aikotoba_current_account

  before_action :authenticate_account!, unless: :aikotoba_controller?

  def authenticate_account!
    return if current_account
    redirect_to aikotoba.new_session_path, flash: {alert: "Oops. You need to Signed up or Signed in." }
  end

  private

  def aikotoba_controller?
    is_a?(::Aikotoba::ApplicationController)
  end
end

Testing

You can use a helper to login/logout by Aikotoba. :warning: It only supports rack testing.

require "aikotoba/test/authentication_helper"
require "test_helper"

class HelperTest < ActionDispatch::SystemTestCase
  include Aikotoba::Test::AuthenticationHelper::System
  driven_by :rack_test

  def setup
    email, password = ["email@example.com", "password"]
    @account = ::Aikotoba::Account.build_by(attributes: {email: email, password: password})
    @account.save
  end

  test "sign_in by helper" do
    aikotoba_sign_in(@account)
    visit "/sensitives"
    assert_selector "h1", text: "Sensitive Page"
    click_on "Sign out"
    assert_selector ".message", text: "Signed out."
  end

  test "sign_out by helper" do
    aikotoba_sign_in(@account)
    visit "/sensitives"
    aikotoba_sign_out
    visit "/sensitives"
    assert_selector "h1", text: "Sign in"
    assert_selector ".message", text: "Oops. You need to Signed up or Signed in."
  end
end
