> Organizations are shared accounts where businesses and open-source projects can collaborate across many projects at once, with sophisticated security and administrative features.
Under _Advanced protocol settings_, set a certificate for _Signing Certificate_.
Once the provider is created, it is advised to download the signing certificate as you will need it later.
## GitHub Configuration
Navigate to your organization settings by going to your organization page at https://github.com/foo, then click Settings.
In the left-hand navigation, scroll down to the Security section and click `Authentication security`
On this page:
- Select the `Enable SAML authentication` checkbox.
- In `sign-on URL`, type `https://authentik.company/application/saml/<authentik application slug>/sso/binding/redirect/`
- For `Issuer`, type `https://github.com/orgs/foo` or the `Audience` you set in authentik
- For `Public certificate`, paste the _full_ signing certificate into this field.
- Verify that the `Signature method` and `Digest method` match your SAML provider settings in authentik.
Once these fields are populated, you can use the `Test SAML configuation` 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.`
