When someone invites you (via e-mail) to a Terraform Cloud organization, the following error might appear on your screen:
The administrator for this organization requires MFA. Please setup MFA for this account or contact your administrator to regain access"
This is happening when you are invited to join a Terraform Organization which is set to require 2-factor authentication but you do not have MFA/2FA configured for your Terraform Cloud account
You need to configure MFA/2FA in your Terraform Cloud account but how it to be configured depends on the way your Terraform Cloud account is created/authenticating:
You have independent Terraform Cloud account (not created through the HCP account) - configure MFA/2FA by following this document: https://developer.hashicorp.com/terraform/cloud-docs/users-teams-organizations/2fa
- You have Terraform Cloud account created through HCP account - configure MFA/2FA for your HCP account by following this document: https://developer.hashicorp.com/hcp/docs/hcp/security/mfa#enabling-mfa
- You have Terraform Cloud account (logging / authenticating through Github) - configure MFA/2FA for you GitHub account by following this document: https://docs.github.com/en/authentication/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication
If the above solution does not help, please open a ticket with the Terraform Cloud support team:
