I have a question about the newly announced [non-unique email](https://auth0.com/changelog#62W58bGFJRK1LQNqINDgW) feature. It’s unclear to me from the announcement what the default configuration for new connections will be and if any changes need to happen if you use the Management API to create new connections. The application I work on requires unique email addresses for accounts, so will this continue to be the default configuration and will any changes be required if you use the Management API to create connections?

Hi @sarah.allen,

Welcome to the Auth0 Community!

Thanks @animesh-sonkar_ukg for the documentation provided, since that is indeed the right place to look.

Your configuration requires unique email addresses, and that will still be the standard way of creating a new connection, while changes will be needed only when setting [Flexible Identifiers](https://auth0.com/docs/authenticate/database-connections/flexible-identifiers-and-attributes). The default way of [Creating a new connection](https://auth0.com/docs/api/management/v2/connections/post-connections) via the Management API still has the `options.attributes.email` object set with the **identifier.active: true** , as that will keep the **email** as the Primary Identifier.

Best regards,

Remus
