Net::SMTPAuthenticationError in Devise::PasswordsController#create when working with devise mailers

Question

I am implementing devise mailers for my application where i have done the following steps:

in model:

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :confirmable,
         :recoverable, :rememberable, :trackable, :validatable
end

and then I added migrations of confirmation_token, confirmed_at, confirmation_sent_at

In devise.rb, I added:

  config.mailer_sender = '[email protected]'
  #config.mailer = 'Devise::Mailer'

In development.rb:

config.assets.raise_runtime_errors = true
config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.smtp_settings = {
      :address => "smtp.gmail.com",
      :port => 587,
      :domain => "mail.google.com",
      :user_name => "[email protected]",
      :password => "somepassword",
      :enable_starttls_auto => true
  }

everything working fine. But the email is not generated. In my console i am getting mail information and link..

my console:

<p>Hello [email protected]!</p>

<p>Someone has requested a link to change your password. You can do this through the link below.</p>

<p><a href="http://localhost:3000/users/password/edit?reset_password_token=M5os3tBYHQrsRaw4TtTt">Change my password</a></p>

<p>If you didn't request this, please ignore this email.</p>
<p>Your password won't change until you access the link above and create a new one.</p>

I haven't added any devise passwords controller / registartion controllers. I am getting a error when i click on Forgot password and enter email and click on "Send me reset password instructions" button. this is the error, i am getting:

After checking some options in google, this one works

Enable access for less secure apps here by logging in with the email address you have provided in smtp configuration.
