Details
[Then a nice table that I don't seem to be able to copy with 11 different authenticators, links to get them, and which work with Mobile, Windows, &/or Browser.]
The list of authentication providers has been tested by Wolters Kluwer and have been determined to be compatible with our systems. However, please be advised, Wolters Kluwer does not endorse or recommend any individual provider, and each firm/user is advised to conduct their own due diligence to select a provider that is appropriate for their business needs."
