Enterprise customers
To regain access to your account after losing an MFA device, please reach out to the admin of the Enterprise account, they should be able to generate and share a temporary token via email from the access tab (edit/pen icon next to the user --> Send MFA Recovery Token button) of the Enterprise account. This token is one time usable and will be valid for 24 hours.
Admins without MFA will not see this feature on the Dashboard.
