Further troubleshooting of email

I was frustrated that SendGrid wasn't working, so I created a new Gmail account w/o 2fa turned on and tried to set that up to send, but I keep getting an error: (530, b'5.7.0 Authentication Required. Learn more at\n5.7.0 https://support.google.com/mail/?p=WantAuthError l19sm864187qkk.99 - gsmtp', '[redacted]@gmail.com') I'm pretty sure I set it up just like in the tutorial, but I can't get it to work. I even verified that I can see the environment variables from the command line. Anyway, I just set it to "try" to send the email and then to print the exception if it doesn't work. That way that product still seems to function. Again, this feature isn't even important to the functioning of the app.
