2fa.directory catalogs services that use multifactor authentication. Of course the idea is to inform consumers of which services satisfy a basic standard of security. Services that are centralised on Cloudflare appear with a green checkmark, as if there is nothing wrong with sharing all your login details with a privacy abusing fiefdom in a country without privacy safeguards through a MitM arrangement.
If one of the auth factors has a MitM, that’s effectively 1 factor less. 2fa becomes like 1fa.
It’s a gross oversight and the bug tracker is limited to MS Github users. A Github user should raise an issue to point this out.
