After activating 2FA (Two Factor Authentication) process in Insightful settings, users receive a unique recovery code, and they are advised to securely store in case they lose access to their account or cannot get the security code from the Authenticator app.
​

If you cannot find their recovery code and are hence unable to deactivate 2FA and/or use Insightful account, its best if you advised your organization's Admin to contact Insightful support via support@insightful.io with any available document attached that can serve as proof of your identity so we can assist further.
