🛠️ Install and Set Up Devise

Add the devise gem to your Gemfile to bring in authentication functionality, then install it and generate the initial configuration. This step creates an initializer and gives you guidance onsetting up mailer options, which Devise uses for password resets and confirmations.

bundle add devise
rails generate devise:install

After installation, configure the default URL options so Devise can generate proper links in emails:

# config/environments/development.rb
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
