devise.rb

devise.setup |config|   config.secret_key = 'e8406bef31a2c5607f3ab4eb0d165f5745a03fca20a9fa7baedd70bc3ffdec638376dda3ac58efb35dbcbaa955b897dcd5519d7458527955af6e9e8d6c9fafb6'    config.mailer_sender = 'please-change-me-at-config-initializers-devise@example.com'    require 'devise/orm/active_record'    config.authentication_keys = [:phone_number] 

user.rb

class user < activerecord::base   # include default devise modules. others available are:   # :confirmable, :lockable, :timeoutable , :omniauthable   devise :database_authenticatable, :registerable,          :recoverable, :rememberable, :trackable, :validatable          has_many :shipments          has_many :comments           def full_name           first_name + " " + last_name         end          def email_required?           false         end      end 

registration_controller

class registrationscontroller < devise::registrationscontroller  private    def sign_up_params     params.require(:user).permit(:first_name, :last_name, :phone_number, :password, :password_confirmation)   end    def account_update_params     params.require(:user).permit(:first_name, :last_name, :phone_number, :password, :password_confirmation, :current_password)   end end 

this how can it. need add following code in config/initializers/devise.rb:

devise.setup |config|   config.secret_key = "whatever secret key"   config.authentication_keys = [ :phone_number ] end 

in login views have add following text_field instead of email field -

<%= f.text_field :phone_number, :class => 'name of class', :placeholder => "phone number" %>   

after step follow how disable email validation in rails device .

add registration_controller instead of have written:

before_filter :configure_permitted_parameters  protected  def configure_permitted_parameters   devise_parameter_sanitizer.for(:sign_up) |u|     u.permit(:first_name, :last_name, :phone_number, :password, :password_confirmation)   end    devise_parameter_sanitizer.for(:account_update) |u|     u.permit(:first_name, :last_name, :phone_number, :password, :password_confirmation)   end end 

that's it
