How to implement a TokenProvider in ASP.NET Identity 1.1 nightly build?

Question

I\'m trying to implement password reset functionality with nightly build of ASP.NET Identity 1.1. There is a UserManager.GetPasswordResetToken method, but it throws an exception

Answer 1

The default token provider implementation is found in the Microsoft.Identity.Owin package:

/// 

/// Token provider that uses a DataProtector to generate encrypted tokens
/// 
public class DataProtectorTokenProvider : ITokenProvider {
    public DataProtectorTokenProvider(IDataProtector protector)

And you do something like this to wire one up using the default data protection provider from your OWIN IAppBuilder

IDataProtectionProvider provider = app.GetDataProtectionProvider();
if (provider != null)
{
    manager.PasswordResetTokens = new DataProtectorTokenProvider(provider.Create("PasswordReset"));
    manager.UserConfirmationTokens = new DataProtectorTokenProvider(provider.Create("ConfirmUser"));
}
