sending email from python 3.4 script, WITHOUT enabling 'less secure apps' in gmail

问题

i would like to send mail using a python 3.4 script, from my gmail address. i use the following code:

import smtplib  

def sendmail():  
    sender='myemail@gmail.com'  
    receiver=['someone@gmail.com']  
    message='text here'  
    try:  
        session=smtplib.SMTP('smtp.gmail.com',587)  
        session.ehlo()  
        session.starttls()  
        session.ehlo()  
        session.login(sender,'mypassword')  
        session.sendmail(sender,receiver,message)  
        session.quit()  
    except smtplib.SMTPException:  
        print('Error, can not send mail!')

if i 'allow less secure apps' in my gmail account, the script works fine. however, if i disable 'less secure apps', it doesn't works (i get a warning email from google, with 'sign-in attempt blocked') . i would like to modify my code, to be able to send mail without enabling this thing.

i have read all the questions and answers regarding similar problems, but did not find any useful answers or methods. someone has any solution for this?

From "Allowing less secure apps to access your account" support page

Google may block sign in attempts from some apps or devices that do not use modern security standards.

A login/password is not a modern mechanism to authenticate. You should implement SASL XOAuth2.
