Organization owners can require organization members, outside collaborators, and billing managers to enable two-factor authentication for their personal accounts, making it harder for malicious actors to access an organization's repositories and settings.

Requirements for enforcing two-factor authentication

Before you can require organization members, outside collaborators, and billing managers to use 2FA, you must enable two-factor authentication for your own personal account.

Warnings:

  • When you require use of two-factor authentication for your organization, members, outside collaborators, and billing managers (including bot accounts) who do not use 2FA will be removed from the organization and lose access to its repositories. They will also lose access to their forks of the organization's private repositories. You can reinstate their access privileges and settings if they enable two-factor authentication for their personal account within three months of their removal from your organization.
  • If an organization owner, member, billing manager, or outside collaborator disables 2FA for their personal account after you've enabled required two-factor authentication, they will automatically be removed from the organization.
  • If you're the sole owner of an organization that requires two-factor authentication, you won't be able to disable 2FA for your personal account without disabling required two-factor authentication for the organization.

Before you require use of two-factor authentication, we recommend notifying organization members, outside collaborators, and billing managers and asking them to set up 2FA for their accounts. You can see if members and outside collaborators already use 2FA on your organization's People page.

  1. In the top right corner of GitHub, click your profile photo, then click Your profile. Profile photo

  2. On the left side of your profile page, under "Organizations", click the icon for your organization. organization icons

  3. Under your organization name, click Settings. Organization settings button

  4. In the organization settings sidebar, click Security. Security settings

  5. Under "Authentication", select Require two-factor authentication for all members, then click Save. Require 2FA checkbox

  6. If prompted, read the information about members and outside collaborators who will be removed from the organization. Type your organization's name to confirm the change, then click Remove members & require two-factor authentication. Confirm two-factor enforcement box

  7. If any members or outside collaborators are removed from the organization, we recommend sending them an invitation that can reinstate their former privileges and access to your organization. They must enable two-factor authentication before they can accept your invitation.

Viewing people who were removed from your organization

To view people who were automatically removed from your organization for non-compliance when you required two-factor authentication, you can search your organization's audit log for people removed from your organization. The audit log event will show if a person was removed for 2FA non-compliance.

    You can also view people who were removed from your organization by using a time frame in your search.

Helping removed members and outside collaborators rejoin your organization

If any members or outside collaborators are removed from the organization when you enable required use of two-factor authentication, they'll receive an email notifying them that they've been removed. They should then enable 2FA for their personal account, and contact an organization owner to request access to your organization.
