Troubleshooting

Gmail

Instead of using your normal Google password, use an App password.

1. Enable 2-Step Verification.. This is needed to create an App password.
2. Create an App password for Mail.

Unauthenticated login (username/password fields)

The parameters username and password are set as optional to support self-hosted runners access to on-premise infrastructure. If you are accessing public email servers make sure you provide a username/password authentication through GitHub Secrets to make the email delivery secure.
