> Organizations are shared accounts where businesses and open-source projects can collaborate across many projects at once, with sophisticated security and administrative features.
Once these fields are populated, you can use the `Test SAML configuration` button to test the authentication flow. If the flow completes successfully, you will see a green tick next to the Test button.
This enables SAML as an authentication _option_. If you want to _require_ SAML for your organization, visit your SSO url at `https://github.com/orgs/foo/sso` and sign in. Once signed in, you can navigate back to the `Authentication security` page and check `Require SAML SSO authentication for all members of the foo organization.`
