Authentication Methods

Passwordless Authentication with Freighter

This template supports passwordless authentication using the Freighter wallet extension. Users can register and log in using their Stellar accounts managed by Freighter.

Setting Up Freighter Authentication

  1. Install Freighter Wallet Extension

  2. Configure Freighter in the Application

    • No additional server-side configuration is needed.
    • Ensure the client-side scripts include calls to the Freighter API.

Registration Flow

  • Users can register by connecting their Freighter wallet.
  • The application stores the user's Stellar public key for authentication.

Login Flow

  • Users authenticate by signing a challenge message using Freighter.
  • The server verifies the signature to authenticate the user.

Multi-Factor Authentication (MFA)

Enhance security by enabling MFA using authenticator apps.

Enabling MFA

  1. Configure Identity Options

    In Startup.cs or Program.cs:

    services.AddIdentity<ApplicationUser, IdentityRole>(options =>
{
    options.SignIn.RequireConfirmedAccount = true;
    options.Tokens.AuthenticatorTokenProvider = TokenOptions.DefaultAuthenticatorProvider;
})
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();

  2. Add MFA Views and Logic

    • Enable MFA Page: Guides users to set up MFA.
    • Login with MFA: Prompts users for the verification code during login.

  3. Update User Interface

    • Include options for users to manage their MFA settings.
