How to send emails from Gmail without turning off "allow less secure apps" setting?

Is there any way to send an email in a Django project without turning on the "allow less secure apps" feature? Is using OAuth2 a must or can I send it using Google's API?

So far, I just use:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = '587'
EMAIL_HOST_USER = 'myemailaddress'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False

But this gives me an SMTPAuthenticationError, which only works when I turn on "allow less secure apps" in Google. Is there any way to circumvent this without using OAuth2 and allow multiple users to login to that account easily?
