Custom Windows GINA authentication

Question

In Windows, the GINA module can be extended to support different ways of authentication. For example, you can already see a support for Fingerprints, Smart Cards, or even Face Recognition (like what Lenovo did with their laptops). What I am trying to achieve is not something as complex as those methods. All what I want is to be able to provide my custom authentication service (i.e My own authentication method at login). Also, I want to know if there is a way to extend the default authentication method (password) so that there is a preprocessing stage of the password before sending it to the Windows Local Authentication Service.

Thank you.

Answer 2

I know the question has been answered, but I couldn't help but notice that no mention was made of the replacement of GINA by Credential Providers. Here are a couple links:

Create Custom Login Experiences With Credential Providers For Windows Vista

ICredentialProvider Interface on MSDN

The new way will not work the same way as GINA did.

Answer 3

additional information to above point:

Windows Vista and later versions of Microsoft Operating systems have replaced Gina with Credential provider's.
