This article addresses an issue where emails are being sent from the default <root@auth0.com> address after an attempt to configure a custom email provider with a custom email address. This guide provides the steps to configure the email passwordless connection correctly and applies to all custom email providers.

• Universal Login
• Passwordless Authentication
• Email Provider

When a custom email provider has been set up in Auth0 but does not have an email defined in the From section of the passwordless email connection, and wishes to have their emails sent from their custom email address instead of the default Auth0 address. For Auth0 to use a custom email provider, in this case, the From address must not be the default one ( <root@auth0.com> ) but the email address of the custom provider (<yourappname@customemailprovider.com>).

To resolve this issue, the From value in the passwordless email settings must be changed to an email address that does not use the auth0.com domain.

1. Navigate to Auth0 Dashboard > Authentication > Passwordless.
2. Select Email, and press Configure to open the configuration window.
3. Select the Settings view.
4. Enter the custom email address in the From field.
5. Enter the custom text for the Subject and Message.
6. Press Save.
