Django Email 发送 SMTP 错误，无法发送邮件

Question

I am trying to send email within my Django project:

# settings.py
EMAIL_HOST_USER = os.getenv('EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = os.getenv('EMAIL_HOST_PASSWORD')
EMAIL_PORT = 587
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_USE_TLS = True

def notify_user(email_address, subject='Subject', message='Some message!') -> None:
    send_mail(
        subject,
        message,
        settings.EMAIL_HOST_USER,
        [email_address],
        fail_silently=False
    )

As I know I need to disable this option ( Gmail Security ), but Gmail don't let me do it.

As a result I got this error:

raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted. Learn more at\n5.7.8  https://support.google.com/mail/?p=BadCredentials f14-20020a056512360e00b00492bbf7db8asm320697lfs.85 - gsmtp')

What can I do? How to disable that option?

Answer 1

Google disabled/discontinued the Less Secure App feature as of May 30th, 2022.

As recommended by @MeL, you could use an alternative but you can still use Gmail to send emails using Django . You can read this blog Mail setup on django using Gmail to help with guiding the setup if you're unfamiliar with setting up Google App Passwords .

In addition to that, you'll need to do one last thing to activate the app password to be used by Django . You should visit the site https://accounts.google.com/DisplayUnlockCaptcha , select continue and you're all set.
