UserManager VerifyUserTokenAsync Always False

Question

I'm generating a usertoken like so

public async Task GenerateCode()
{

    var code = await UserManager.GenerateUserTokenAsync("heymega", new Guid("16139fcd-7ae0-449c-ad1c-f568bbe46744"));


}

I then pass the same token into another action via a separate request

public async Task ValidateCode(string code)
{

    var valid = await UserManager.VerifyUserTokenAsync(new Guid("16139fcd-7ae0-449c-ad1c-f568bbe46744"), "heymega", code); //Returns False

}

However, the response from the VerifyUserTokenAsync method is always false.

If I were to generate the code and verify within the same action

public async Task GenerateCode()
{

    var code = await UserManager.GenerateUserTokenAsync("heymega", new Guid("16139fcd-7ae0-449c-ad1c-f568bbe46744"));

    var valid = await UserManager.VerifyUserTokenAsync(new Guid("16139fcd-7ae0-449c-ad1c-f568bbe46744"), "heymega", code); //Returns True

}

It returns true.

Why can't the Verify method verify the code in a separate request? Am I missing something obvious?

Answer 1

I finally figured this after pulling my hair out for hours. You need to URL encode the code and I decided to use the HttpUtility class for this.

HttpUtility.UrlEncode(code);

When it comes to verifying the code, you do not need to URL decode the code.
