Google为什么拒绝我的Ruby on Rails应用中的电子邮件？

Question

I'm using ruby on rails to send some emails:

I wanted to test ActionMailer with my personal gmail account, from my console. however google is displaying the following errors:

Sign-in attempt was blocked

Someone just used your password to try to sign in to your account from a non-Google app. Google blocked them, but you should check what happened. Review your account activity to make sure no one else has access. Check

I used to be able to just use any of the answers from these questions:

Can't send email using Gmail on Heroku

Can't send mail with gmail stmp server (in discourse)

why is devise not sending email via gmail smtp?

But now I just can't send emails using my google account.

What changed? How do I configure my gmail to be able to do this?

This is the code I run from my console:

ActionMailer::Base.delivery_method = :smtp 
ActionMailer::Base.smtp_settings = {
  address:              'smtp.gmail.com', 
  port:                 587, 
  domain:               'gmail.com',
  authentication:       'plain', 
  enable_starttls_auto: true, 
  user_name:            'some@gmail.com',
  password:             '********'
}

mailer = ActionMailer::Base.new

# send mail:
mailer.mail(from: 'some@gmail.com', to: 'some_other@gmail.com', subject: 'test', body: "Hello, you've got mail!").deliver

您可以使用您的Google帐户启用两要素身份验证，并写下他们给您的代码（上次我检查了他们给了您的密码中的大约10个），然后在发送电子邮件时使用这些代码之一对您的Rails应用程序进行身份验证您的帐户密码。
