1. Describe your incident:
I have setup the server.conf file to send emails using gmail service. However, when I test an alert I get the error below:

# Email transport
transport_email_enabled = true

transport_email_port = 587
transport_email_use_auth = true

transport_email_auth_username = xxxxxx@gmail.com
transport_email_auth_password = xxxxxxxxxxxxx
transport_email_subject_prefix = [graylog]

Ok, this is odd. I didn’t realize the System tab would give me more info. It’s stating “Username and Password not accepted”, but I can use the creds I have entered manually to log into gmail…

And the answer is use an App Password.

I don’t know if someone should delete this or leave it up for someone like me fumbling through all of this in the future.
