Python SMTPLIB , SSL Library Error --> smtplib.SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted)

Question

我的 python 程序有问题。我在程序中输入了正确的电子邮件和密码信息，错误如下所示

import smtplib, SSL 

email="belginjarosh46@gmail.com"
password="my password"
port = 465

context = ssl.create_default_context()

server =smtplib.SMTP_SSL("smtp.gmail.com",port,context=context) 
server.login(email,password)
message=" Hi I Am Belgin Android "
sender_mail=email,
receiver_email="belginjarosh46@gmail.com"
server.sendmail(sender_mail,receiver_email,message)

错误：

总结一下 - 我猜问题是 Google 不允许您使用默认用户密码登录，尤其是（但不仅限于）在使用第二因素身份验证时。 因此，对于使用 3rd 方应用程序的密码，它 requires creating app specific passwords。
