Adding a Domain Name for Your User Pool


The Domain name tab appears only when you're editing an existing user pool.

On the Domain name tab, you can enter your own prefix domain name. The domain for your app is https://<domain_prefix>.auth.<region>

The full URL for your app will look like this example:<client_id_value>

For more information, see Configuring a User Pool Domain.


Before you can access the URL for your app, you must specify app client settings such as callback and redirect URLs. For more information, see Configuring App Client Settings.
