Allow less secure apps: ON Some apps and devices use less secure sign-in technology, which could leave your account vulnerable. You can turn off access for these apps (which we recommend) or choose to use them despite the risks.

Answer 2

None of the less-secure options worked for me. What worked in the end was setting up 2-factor authentication, and then generating an app-specific password. Instructions here: https://support.google.com/domains/answer/9437157

Answer 3

I had exactly the same problem. Yes, it worked. By enabling your gmail account security setting -> Allow less secure app, I was able to send a simple email from one gmail to another gmail account.

WARNING: Allowing low security for apps accessing your Google account is not recommended by google. It can be a security threat. Turn it OFF after the experiment.

Answer 4

Go to Google's Account Security Settings: www.google.com/settings/security

Find the field "Access for less secure apps". Set it to "Allowed".

Try your script again, changing server.sendemail() to server.sendmail()
