Just sharing a finding, not sure how updated is this database but I found helpful to consult it specially if I’m looking for some service like for example a credit card and I’m between two providers but one doesn’t offer TOTP I can use it as a criteria to decide. Most American institutions still a long way to go in this realm.
Some curiosity for example, was to find that Mullvad doesn’t offer TOTP. Not that I find essential for a VPN provider but still that since they are so well praised in my books this would be an expected feature.
