About organization invitations
When you invite someone to become a member of your organization, the person receives an email with an invitation link. To join the organization, the invitee clicks the invitation link in the email.
You can use a person's GitHub username or email address for the invitation.
Note: If you use an email address for the invitation, the invitee will only be able to accept the invitation if the email address matches with a verified email address associated with the invitee's personal account on GitHub. For more information, see "Verifying your email address."
If an invitee's personal account has been flagged, the invitee won't be able to accept any new or pending invitations to join organizations.
If your organization has a paid per-user subscription, an unused license must be available before you can invite a new member to join the organization or reinstate a former organization member. For more information, see "About per-user pricing."
If an invitee does not accept the invitation within seven days, the pending invitation expires automatically.
If your organization requires members to use two-factor authentication, users that you invite must enable two-factor authentication before accepting the invitation. For more information, see "Requiring two-factor authentication in your organization" and "Securing your account with two-factor authentication (2FA)."
Organizations that use GitHub Enterprise Cloud can implement SCIM to add, manage, and remove organization members' access to GitHub.com through an identity provider (IdP). For more information, see "About SCIM for organizations" in the GitHub Enterprise Cloud documentation.
