V2 Credential Provider Sample
This sample implements a simple v2 credential provider. A credential provider allows a 3rd party to provide an alternate way of logging on. For example, a fingerprint solution vendor would write a credential provider to interact with the user and send the appropriate credentials to the system for authentication. Questions should be sent to credprov@microsoft.com.
This sample implements a simplified credential provider that is based on the password credential provider that ships with Windows. When run, the credential provider should enumerate two tiles, one for the administrator and one for the guest account. Note that the guest account must be enabled for that tile to log on successfully. (The guest account is disabled by default.)
This sample demonstrates simple password based log on and unlock behavior. It also shows how to construct a simple user tile and handle the user interaction with that tile.
Note that this sample does not demonstrate the following:
- other credential provider scenarios, like participating in credui or handling change password.
- every possible field that you can put in your user tile
- any network access prior to local authentication (the Pre-Logon Access Provider (PLAP) behavior)
- an event based credential provider (like a smartcard or fingerprint based system)
Operating system requirements
Client
Windows 8.1
Server
Windows Server 2012 R2
Build the sample
- Start Visual Studio and select File > Open > Project/Solution.
- Go to the directory named for the sample, and double-click the Visual Studio Solution (.sln) file.
- Press F7 or use Build > Build Solution to build the sample.
Run the sample
Copy SampleV2CredentialProvider.dll to the System32 directory and run Register.reg from an elevated command prompt. The credential should appear the next time a logon is invoked (such as when logging off or rebooting the machine).
