# Remove a custom domain

> Disconnect a custom domain so the portal falls back to its default address without locking partners out.

> For partner ops cleaning up a domain that is changing or retiring.

When you rebrand or move to a new hostname, you remove the old domain so the portal stops serving there. After removal the portal falls back to the default subdomain, so partners are never locked out entirely, just moved. This guide removes the domain and confirms the fallback.

## What you'll achieve

A removed custom domain, with the portal back on its default address (or a new domain you set up), and a plan to point partners at the new location.

## Before you start

<Steps>
  <Step title="Plan the communication">
    Partners using the old domain will need the new address, so plan to tell them before or right after you remove it.
  </Step>

  <Step title="Confirm admin access">
    You need admin access to portal settings to remove a domain.
  </Step>
</Steps>

## Steps

<Steps>
  <Step title="Open domain settings">
    Go to [Portal settings](https://app.introw.io/settings/portal) and open the custom domain configuration.
  </Step>

  <Step title="Remove the domain">
    Remove the custom domain you no longer want to serve. The portal stops responding on that hostname and falls back to the default subdomain, so it stays reachable.
  </Step>

  <Step title="Confirm the fallback">
    Confirm the portal loads on the default subdomain, or on a new custom domain if you set one up, and clean up the old DNS records at your provider once nothing depends on them.
  </Step>
</Steps>

## Verify it worked

The removed domain no longer serves the portal, and the portal loads on its fallback address so partners can still get in.
