Create and manage domains for your Organization

Authorization policies in Astro are based on email domains, which ensures that all users with an approved email domain authenticate with a specific authentication method. Domains can be mapped to single sign-on (SSO) methods so that users who have an email with a domain are automatically directed to your SSO platform when they sign in to Astro.

You can only configure a single domain for an SSO connection. However, if you have multiple managed domains, then you can set up multiple different SSO connections, with a separate SSO connection for each domain.

Create a domain

1. In the Astro UI, click Organization Settings, then click Authentication.
2. In the Managed Domains menu, click Managed Domain.
3. In the Domain field, enter the domain that you want to map.
4. Click Create. The domain is added to your Managed Domains and marked as Unverified.
5. In the entry for your domain, click Verify. A new window appears with steps to verify your domain.
6. Follow the steps to verify your domain. If you can’t complete the steps yourself, contact the administrator for your domain and ask them to complete the steps instead.
7. Click Verify to notify Astro to check your DNS record.

After your domain is verified, you can map the domain to an SSO connection. Mapping a domain ensures that all users with the same email address domain have the same authentication experience when they sign in to Astro. You can later use this mapping to enforce specific sign in methods for users with emails from a specific domain. See Configure SSO.

Delete a domain

1. In the Astro UI, click Organization Settings, then click Authentication.
2. In the Managed Domains menu, click the trash bin next to the domain you want to delete.
3. Follow the prompts to confirm the deletion.
