Answer 1

Add the :rememberable option in your User model

class User < ActiveRecord::Base

  devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable,
         :validatable, :token_authenticatable, :lockable, :omniauthable

  # ...

end

Create a migration to add the remember_created_at column in the table of users

class AddRememberCreatedAtToUsers < ActiveRecord::Migration
  def change
    add_column :users, :remember_created_at, :datetime
  end
end

If you're not using the Devise default views, add the checkbox to your view:

<%= f.check_box :remember_me %> <%= f.label :remember_me %>

I think that's all you need...

And un-comment in devise.rb: config.remember_for = 2.weeks – Embonpoint

Answer 2

You may encounter issues with rememberable if you write your own authentication strategies. The resource object (e.g. User) returned by your authenticate! method needs to be responsible for setting the resource.remember_me from the form data. This is normally handled by the parent Authenticable's validate method. If you don't use this method, you'll have to set it yourself.
