Hey everyone,
I prefer to post on this topic instead of creating another one. So I am currently looking for a 2 factor authentication solution for company. I have tested OpenOTP but the offline authentication, which is very important for my company, isn’t possible.
So I am asking you, if you know any solution that support OS login with a second factor even when the laptop is offline (for Windows, Linux and Mac OS). Moreover, the solution has to support SAML 2.0 and SSO. And off course, if you have an idea of the price it will be wonderful 
Regards !
