# Update Tenant hostnames

You can change the hostname of child accounts of your Tenant account. This feature is useful if, for example, your company rebrands and changes its company name, you can update the hostname to reflect the rebranding.

To update a Tenant hostname:

1. Log in to a Service Provider Tenant account.

2. Click Menu icon **>** **Service Provider > Tenants**. The **Tenants List** page appears.

3. Click Ellipsis Vertical icon next to the account you want to update.

4. Click **Supported Hostnames**. The **Supported Hostnames** dialog box appears.

5. Click **Edit**. The **Edit Supported Hostnames** dialog box appears.

note
Edit is available only if you have the option of changing the child tenant hostname.

6. Enter the **New Subdomain**.

7. Under **Select other hostname to continue supporting**, do the following as required:

   - Select an existing hostname if you want to continue to support that hostname. If you select that option, users can either access their account from the new hostname URL or the old one. If you select this option, the hostname appears in the **Other Supported Hostname** field.
   - Select **Do not support an additional hostname** if you do not want to support an existing hostname.

8. Click **Next**. The **Confirm Supported Hostnames** dialog box appears.

9. Review the information on the dialog box to ensure the changes are as expected.

- Email template variables
- Soft tokens and Smart Credentials

10. Enter your **Company Name** to confirm the changes.

11. Click **Save**. You are returned to the **Tenants List** page.
