Login to Ruby on Rails console with email and password

If you ever need to protect your rails console (or need to authenticate for any other reason) you can create a new file in config/initializers with code like this:

module Rails
  module ConsoleMethods
    def self.included(_base)
      puts 'Enter your email:'
      email = gets
      user = User.find_by(email: email.strip)
      unless user
        puts 'Email not found in database! Exiting...'
        exit
      end

      puts 'Enter your password:'
      pass = $stdin.noecho(&:gets)
      if user.valid_password?(pass.strip)
        puts "Welcome #{user.email}!"
      else
        puts 'Provided password is not correct! Exiting...'
        exit
      end
    end
  end
end

You can of course add condition so this code will be executed only on production and/or staging.

Note 1: If you are using devise for authentication as it is is done in my example above please make sure that your file is loaded after config/initializers/devise.rb which means that your file’s name should be “bigger” than devise.rb, for example: perform_authentication_in_console.rb

Note 2: with ruby version “2.3” or higher you are able to use IO::console.getpass instead of $stdin.noecho(&:gets)
