Password reset token provider in ASP.NET core - IUserTokenProvider not found

Question

Hello,

In order to getting password reset work I need to register an IUserTokenProvider instance into DI.

Without it I get exception at following line:

var result = await _userManager.ResetPasswordAsync(user, token, password);

"No IUserTokenProvider named 'PasswordResetTokenProvider' is registered."

That makes sense so I tried to register it in the DI:

services.AddSingleton<IUserTokenProvider<User>, DataProtectorTokenProvider<User>>();

But the interface IUserTokenProvider does not exists. Do you know how to solve this?

Thanks

I'm not sure if it's workaround or normal approach, but the IUserTwoFactorTokenProvider interface seems to be a right way. IUserTokenProvider appears to no longer exists.

Figured out that I have to register the provider manually in the identity:

services.AddIdentity<User, Role>(options =>
            {
                ...
                options.Tokens.ProviderMap.Add("Default", new TokenProviderDescriptor(typeof(IUserTwoFactorTokenProvider<User>)));
            })

And the optional configuration in ConfigureServices:

services.Configure<DataProtectionTokenProviderOptions>(o =>
        {
            o.Name = "Default";
            o.TokenLifespan = TimeSpan.FromHours(1);
        });

And the password reset / email validation tokens are working now.
