# Create a DNS entry

<Note>This document covers step one of the [Single sign-on (SSO) setup](/docs/administration/single-sign-on) process, and shouldn't be completed independently.</Note>

For security and ownership verification, all domains associated with an SSO connection must have a DNS TXT entry added.

If your users span multiple domains and all are required to sign in using SSO, this process must be completed for each domain.

<Note>This step must be completed before Matillion can start any configuration.</Note>

The specific steps to create a DNS entry vary by provider, but the following generic steps should be followed:

1. Sign in to your DNS provider, such as Cloudflare, Route 53, or GoDaddy.

2. Open the DNS management page, look for a section labelled **DNS**, **DNS Management**, **Zone Editor**, or **Advanced DNS Settings**.

3. Add a new TXT record, using the following values:
   * **Name/Host/:** Enter `@` to apply to the root domain.
   * **Value:** `matillion:[domain]-sso` replacing `[domain]` with your primary email domain, and converting any special characters to dashes. For instance, `example.com` would become `matillion:example-com-sso`.
   * **TTL**: If editable, use the default value or set it to 1 hour.

4. Save the record.

5. Continue the steps in [Single sign-on (SSO) setup](/docs/administration/single-sign-on).
