Sending and email using python - Problem causes by last Google policy update-CodePudding

First of all I am a beginner in python and I am trying to learn how to send an email using python. All the tutorials on the web that i have red explain how to do it using Gmail. But, from 30/05/2022 (despite the fact that everybody is free to do whatever he wants with his account) google has a new politic that states:

To help keep your account secure, starting May 30, 2022 , Google will no longer support the use of third-party apps or devices that only ask for your username and password for you. sign in to your Google account.

So my question is there any other way to send an email using python (include to an email account belonging to an other company)?

Btw here my function to send an email:

def send_email_fct(filename, filepath, fromaddr, mdpfrom, toaddr):
"""" filename: file name to be sent with extension
     filepath: file path of the file to be sent
     fromaddr: sender email address
     mdpfrom: password of sender email address
     toaddr: receiver email address"""

msg = MIMEMultipart()  # instance of MIMEMultipart
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "data file"

body_email = "Body_of_the_mail"
msg.attach(MIMEText(body_email, 'plain'))

attachment = open(filepath, 'rb')  # open the file to be sent

p = MIMEBase('application', 'octet-stream')  # instance of MIMEBase
p.set_payload(attachment.read())
encoders.encode_base64(p)
p.add_header('Content-Disposition', "attachment; filename= %s" % filename)

msg.attach(p)  # attach the instance 'p' to instance 'msg'

s = smtplib.SMTP('smtp.gmail.com', 587)  # SMTP
s.starttls()
s.login(fromaddr, mdpfrom)

text = msg.as_string()

s.sendmail(from_email_addr, toaddr, text)  # sending the email

s.quit()  # terminating the session

And I get this error:

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 c12-20020aa7d60c000000b0042be14040c1sm2612116edr.86 - gsmtp')

To fix this problem, i think that the only line that need to be change is this one:

s = smtplib.SMTP('smtp.gmail.com', 587)

If you know by what i can change it or if you see any other error, it will help me a lot! :-)

Thank you for your help

Solved it by creating App password. You must got to Google account. Security tab, active 2 Step Verification. After this new option under "Signing in to Google" the "App passwords" option will be actived. Just create one app password and use as password to authenticate
