Two Factor Token Provider

Provider class - obviously needs tweaking to generate more unique token

public class HedgehogEmailTwoFactorAuthentication<TUser> : IUserTwoFactorTokenProvider<TUser> where TUser : HedgehogUserAccount
    {
        public Task<bool> CanGenerateTwoFactorTokenAsync(UserManager<TUser> manager, TUser user)
        {
            if (manager != null && user != null)
            {
                return Task.FromResult(true);
            }
            else
            {
                return Task.FromResult(false);
            }
        }

        // Genereates a simple token based on the user id, email and another string.
        private string GenerateToken(HedgehogUserAccount user, string purpose)
        {
            string secretString = "coffeIsGood";
            return secretString + user.Email + purpose + user.Id;
        }

        public Task<string> GenerateAsync(string purpose, UserManager<TUser> manager, TUser user)
        {
            return Task.FromResult(GenerateToken(user, purpose));
        }

        public Task<bool> ValidateAsync(string purpose, string token, UserManager<TUser> manager, TUser user)
        {
            return Task.FromResult(token == GenerateToken(user, purpose));
        }
    }

Add to service in MVC

services.AddIdentityCore<CustomerAccount>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddRoles<IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddTokenProvider("Default", typeof(HedgehogEmailTwoFactorAuthentication<CustomerAccount>))
    .AddDefaultUI();
