Uncomment the line 3 as above in your configuration.

Generally speaking, Rails does not provide authentication by itself. However, most developers using Rails leverage libraries such as Devise or AuthLogic to provide authentication.

To enable authentication it is possible to use Devise gem.

Install it using:
```

Then install it to the user model:
```

rails generate devise:install

Next, specify which resources (routes) require authenticated access in routes:
```

Rails.application.routes.draw do authenticate :user do resources :something do # these resource require authentication ... end end

devise_for :users # sign-up/-in/out routes

root to: 'static#home' # no authentication required end

To enforce password complexity, it is possible to use [zxcvbn gem](https://github.com/bitzesty/devise_zxcvbn). Configure your user model with it:
```

class User &lt; ApplicationRecord devise :database_authenticatable, # other devise features, then :zxcvbnable end

And configure the required password complexity:
