Is it possible to log into gmail via Python without the "Access for dubious applications" checkbox?

Question

Python

I tried using smtplib to log into gmail mail, but I wrote an error:
smtplib.SMTPServerDisconnected: Connection unexpectedly closed

Later, in my account settings, I turned on the Access for dubious applications checkbox. And it worked, but in the future I will need to go to a different account. Can I log into my account without this checkbox?

Maybe I didn't explain well, but I'll be glad to answer
