Plutonium Rodauth Authentication

Plutonium integrates with Rodauth via rodauth-rails for authentication. This provides a full-featured, secure authentication system.

Installation

Step 1: Install Rodauth Base

rails generate pu:rodauth:install

This installs:

• Required gems (

  rodauth-rails

  ,

  bcrypt

  ,

  sequel-activerecord_connection

  )

• app/rodauth/rodauth_app.rb

  - Main Roda app

• app/rodauth/rodauth_plugin.rb

  - Base plugin

• app/controllers/rodauth_controller.rb

  - Base controller

• config/initializers/rodauth.rb

  - Configuration

• app/views/layouts/rodauth.html.erb

  - Auth layout
• PostgreSQL extension migration (if using PostgreSQL)

Step 2: Create Account Type

Choose the appropriate generator for your use case:

# Basic user account
rails generate pu:rodauth:account user

# Admin with 2FA and security features
rails generate pu:rodauth:admin admin

# Customer with entity association
rails generate pu:rodauth:customer customer

Account Generators

Basic Account (

pu:rodauth:account

)

Creates a standard user account with configurable features:

rails generate pu:rodauth:account user [options]

Options:

--defaults

--kitchen_sink

--primary

--no-mails

--argon2

--api_only

Feature Options:

--login

--logout

--remember

--create_account

--verify_account

--reset_password

--change_password

--change_login

--verify_login_change

--otp

--webauthn

--recovery_codes

--lockout

--active_sessions

--audit_logging

--close_account

--email_auth

--sms_codes

--jwt

--jwt_refresh

Admin Account (

pu:rodauth:admin

)

Creates a secure admin account with:

• Multi-phase login (email first, then password)
• TOTP two-factor authentication (required)
• Recovery codes
• Account lockout
• Active sessions tracking
• Audit logging
• No public signup (accounts created via rake task)

rails generate pu:rodauth:admin admin

Creates rake task:

# Create admin account
rails rodauth_admin:create[admin@example.com,password123]

Customer Account (

pu:rodauth:customer

)

Creates a customer account with an associated entity (organization/company):

rails generate pu:rodauth:customer customer
rails generate pu:rodauth:customer customer --entity=Organization
rails generate pu:rodauth:customer customer --no-allow_signup

Options:

--entity=NAME

--no-allow_signup

This creates:

• Customer account model
• Entity model (Organization, Company, etc.)
• Membership join model
• Has-many-through associations

Connecting Auth to Controllers

Include in Resource Controller

# app/controllers/resource_controller.rb
class ResourceController < PlutoniumController
  include Plutonium::Resource::Controller
  include Plutonium::Auth::Rodauth(:user)  # Use :user account
end

Multiple Account Types

# app/controllers/admin_controller.rb
class AdminController < PlutoniumController
  include Plutonium::Resource::Controller
  include Plutonium::Auth::Rodauth(:admin)
end

# app/controllers/customer_controller.rb
class CustomerController < PlutoniumController
  include Plutonium::Resource::Controller
  include Plutonium::Auth::Rodauth(:customer)
end

What It Provides

Including

Plutonium::Auth::Rodauth(:name)

Plugin Configuration

# app/rodauth/user_rodauth_plugin.rb
class UserRodauthPlugin < RodauthPlugin
  configure do
    # Features enabled for this account
    enable :login, :logout, :remember, :create_account, ...

    # URL prefix (non-primary accounts)
    prefix "/users"

    # Password storage
    account_password_hash_column :password_hash

    # Controller for views
    rails_controller { Rodauth::UserController }

    # Model
    rails_account_model { User }

    # Redirects
    login_redirect "/"
    logout_redirect "/"

    # Session configuration
    session_key "_user_session"
    remember_cookie_key "_user_remember"
  end
end

Customization

Custom Login Redirect

# app/rodauth/user_rodauth_plugin.rb
configure do
  login_redirect { "/dashboard" }

  # Or dynamically based on user
  login_redirect do
    if rails_account.admin?
      "/admin"
    else
      "/dashboard"
    end
  end
end

Custom Validation

configure do
  # Add custom field validation
  before_create_account do
    throw_error_status(422, "name", "must be present") if param("name").empty?
  end

  # After account creation
  after_create_account do
    Profile.create!(account_id: account_id, name: param("name"))
  end
end

Password Requirements

configure do
  # Minimum length
  password_minimum_length 12

  # Custom complexity
  password_meets_requirements? do |password|
    super(password) && password.match?(/\d/) && password.match?(/[^a-zA-Z\d]/)
  end
end

Multi-Phase Login

configure do
  # Ask for email first, then password
  use_multi_phase_login? true
end

Prevent Public Signup

configure do
  before_create_account_route do
    request.halt unless internal_request?
  end
end

Email Configuration

Emails are sent via Action Mailer. Configure delivery in your environment:

# config/environments/production.rb
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address: "smtp.example.com",
  port: 587,
  user_name: ENV["SMTP_USER"],
  password: ENV["SMTP_PASSWORD"]
}

Custom Email Templates

Override templates in

app/views/rodauth/user_mailer/

<%# app/views/rodauth/user_mailer/reset_password.text.erb %>
Hi <%= @account.email %>,

Someone requested a password reset for your account.

Reset your password: <%= @reset_password_url %>

If you didn't request this, ignore this email.

Portal Integration

Selecting Auth for Portal

When generating a portal, select the Rodauth account:

rails generate pu:pkg:portal admin
# Select "Rodauth account" when prompted
# Choose "admin" account

Manual Portal Auth Setup

# packages/admin_portal/lib/engine.rb
module AdminPortal
  class Engine < Rails::Engine
    include Plutonium::Portal::Engine

    # Require authentication
    config.before_initialize do
      config.to_prepare do
        AdminPortal::ResourceController.class_eval do
          include Plutonium::Auth::Rodauth(:admin)

          before_action :require_authenticated

          private

          def require_authenticated
            redirect_to rodauth.login_path unless current_user
          end
        end
      end
    end
  end
end

API Authentication

For JSON API authentication:

rails generate pu:rodauth:account api_user --api_only --jwt --jwt_refresh

This enables:

• JWT token authentication
• Refresh tokens
• No session/cookie handling

Using JWT

# Login
POST /api_users/login
Content-Type: application/json

{"login": "user@example.com", "password": "secret"}

# Response includes JWT
{"access_token": "...", "refresh_token": "..."}

# Authenticated requests
GET /api/posts
Authorization: Bearer <access_token>

Internal Requests

Create accounts programmatically:

# Using internal request
Rodauth::Rails.app(:user).rodauth(:user).create_account(
  login: "user@example.com",
  password: "secure_password"
)

# Or via model (if allowed)
User.create!(
  email: "user@example.com",
  password_hash: BCrypt::Password.create("secure_password"),
  status: 2  # verified
)
