Asp.NET Identity 2 giving “Invalid Token” error

Question

I\'m using Asp.Net-Identity-2 and I\'m trying to verify email verification code using the below method. But I am getting an \"Invalid Token\"

Answer 1

Related to chenny's 3. Different instances of token providers .

In my case I was passing IDataProtectionProvider.Create a new guid every time it got called, which prevented existing codes from being recognized in subsequent web api calls (each request creates its own user manager).

Making the string static solved it for me.

private static string m_tokenProviderId = "MyApp_" + Guid.NewGuid().ToString();
...
manager.UserTokenProvider =
  new DataProtectorTokenProvider(
  dataProtectionProvider.Create(new string[1] { m_tokenProviderId } ))
  {
      TokenLifespan = TimeSpan.FromMinutes(accessTokenLifespan)
  };
