As for personal fun and challenge, I wanted to add a way to login on my own personal computers. All are currently using Windows 7.
Normally this would use ICredentialProvider or something like that. Basically the goal here is to have 2 way to login, the normal user/password one and the alternative (mine) with a Yubikey.
Is there any where I could look to find some resources on how to achieve this using C# ?
