Django SmtpLib SMTPAuthenticationError 535 B 5 7 8: When Username and Password Won’t Cut It

When working with Django’s built-in email backend, you might encounter a frustrating error that prevents your application from sending emails successfully. The dreaded SMTPAuthenticationError with code 535 has become all too familiar for many developers. At its core, this error indicates that the SMTP server has rejected the username and password provided during authentication.

In this case, we’re dealing with a Gmail account and Django’s SmtpLib library.

The error message itself is quite explicit: “Username and Password not accepted.” It seems like a straightforward issue, but the reality is often more complex. After all, you’ve double-checked your email address and password – what else could be going wrong?

Let’s dive into some possible causes of this error. First, ensure that less secure app access is enabled in your Google Account settings. This feature allows apps to use your Gmail account credentials for authentication.

If you’re using 2-Step Verification, generate an App Password and use that instead.

Another potential culprit is the SMTP server configuration. Verify that your Django application is configured correctly. Check the SMTP host, port, username, and password in your settings file.

Make sure they match the exact credentials used to set up your Gmail account.

If you’ve checked all these boxes and are still experiencing issues, it might be worth exploring alternative solutions. Consider using a more secure method of authentication, such as OAuth 2.0, or switching to a different email service provider.

By understanding the underlying causes of the SMTPAuthenticationError and taking targeted steps to resolve the issue, you’ll be well on your way to successfully sending emails with your Django application.

In conclusion, tackling the Django SmtpLib SMTPAuthenticationError 535 B 5 7 8 ‘Username and Password not accepted’ error requires a systematic approach and attention to detail.
