+# Enforce two-factor authentication (2FA)
+
+Two-factor authentication can be enforced for the whole organization to ensure that all users who access
+the organization have two-factor authentication enabled.
+
+## Before enforcing two-factor authentication
+
+Before you enforce two-factor authentication for your organization, consider
+users without 2FA enabled will immediately lose access to the organization and
+subsequent pipelines.
+
+Users can set up two-factor authentication by following this [tutorial].
+
+## Steps to enforce two-factor authentication
+
+To enforce two-factor authentication:
+
+- You must be logged in as an Administrator
+- Visit the Organization's [security settings]
+- Check **Enforce two-factor authentication**
+- Click **Update Access Control**
+
+## Programmatically enforcing two-factor authentication
+
+Please review the GraphQL [cookbook] for instructions on how to enable
+enforced 2fa via the GraphQL API.

-Currently, it's not possible to enforce 2FA in Buildkite for members of an organization. However, you can check the current 2FA status using the [User Settings](https://buildkite.com/user/settings) page for your organization. You'll see a 2FA badge next to the users who have it enabled.

-If conducting a regular audit is not enough, many SSO providers can enforce 2FA. In turn, Buildkite can enforce SSO for members of an organization. If you're already using an SSO provider this may be a solution. Read more about [using SSO with Buildkite](/docs/integrations/sso).
