Email Authentication

If you wish to use email authentication, you must configure your Rails application to send email. Read here for more information.

I recommend using mailcatcher for development.

mailcatcher development example configuration:

# config/environments/development.rb
Rails.application.configure do
  config.action_mailer.default_url_options = { host: '' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = { address: '', port: 1025 }

You also may want to configure mail_sender at devise initializer if you don't use your own mailer class

devise configuration:

# config/initializers/devise.rb
Devise.setup do |config|
  config.mailer_sender = ""

If you wish to send custom e-mails instead of using the default devise templates, you can do that too.
