It is very strange type error I have user and want to sign in through devise but I am facing strange error. I sign up successfully but when I try to login it through and error of invalid email or password here is may some code.

class ApplicationController < ActionController::Base
    before_filter :update_sanitized_params, if: :devise_controller?
    protected
    def update_sanitized_params

     devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:email,   :password, :password_confirmation, :role)}
     devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password) }
   end   


 end

My form is

<h2>Sign in</h2>

<%= form_for(resource, :as => resource_name, :url => user_session_path(resource_name)) do |f| %>
  <div><%= f.label :email %><br />
  <%= f.email_field :email, :autofocus => true %></div>

  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>

  <% if devise_mapping.rememberable? -%>
    <div><%= f.check_box :remember_me %> <%= f.label :remember_me %></div>
  <% end -%>

   <div><%= f.submit "Sign in" %></div>
<% end %>

<%= render "devise/shared/links" %>

 config.authentication_keys = [ :email ]
 config.case_insensitive_keys = [ :email ]
 config.strip_whitespace_keys = [ :email ]
 config.reconfirmable = true
 config.password_length = 8..128

I have resolve the problem. The problem was with encrypt password there was a before save call back which encrypts the password but devise already have feature so password was encrypted twice. Thanks guys for help.
