# Client Portals

Choose to create a portal for your clients, customers, or partners by selecting who will be using the app: **"My clients or customers (external users)"** when creating a new app.

This then becomes a portal - the main difference being the way your users login and offering a white labeled experience.&#x20;

**Login page example:**&#x20;

Your **Subdomain** is the given URL for your portal that your users will use to login until you set a [custom domain](/stacker-astra/workspace-portals-and-apps/portals/custom-domain.md) (if you wish to).&#x20;

Under **Appearance** you can set a custom logo and change the app color.&#x20;

{% hint style="info" %}
To share this app with your users you will need to add them under [Users](/stacker-astra/builder-agent-mode/share-with-your-users.md)

To control what your users see when they login, set up [permissions](/stacker-astra/manage-data-using-ai/add-user-permissions.md)

See more about the login flow [here](/stacker-astra/builder-agent-mode/share-with-your-users/log-in-flow.md#log-in-flow-for-portals).
