Customizing User Sign-Up Options in ZITADEL LoginPolicy

Question

Pulumi · Accepted Answer

To customize user sign-up options in ZITADEL, we can leverage the `LoginPolicy` resource from the ZITADEL Pulumi provider. This resource allows you to configure various aspects of the login process, such as Multi-Factor Authentication (MFA) requirements, allowed identity providers, and whether users can register themselves.

Below is a Pulumi program in TypeScript that demonstrates how to customize the `LoginPolicy` for a ZITADEL organization. This example sets up a `LoginPolicy` that enables user registration, allows passwordless logins, and requires MFA with specific factors. Before diving into the code, ensure you have ZITADEL provider and Pulumi CLI set up in your environment.

Here's what each part of the code accomplishes:
- The `zitadel.LoginPolicy` resource is created, which dictates the login policy applied to an organization in ZITADEL.
- `allowRegister` is set to `true`, which allows new users to register.
- `passwordlessType` specifies the method of passwordless authentication we're enabling.
- MFA options such as `forceMfa`, `multiFactors`, and `secondFactors` are configured to establish how MFA should be enforced.
- Additional options are set to customize the user authentication experience further, including provisions for external identity providers and sign-up flows.

Now let's take a look at the program:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as zitadel from "@pulumi/zitadel";

// Define a new LoginPolicy for an organization in ZITADEL.
const loginPolicy = new zitadel.LoginPolicy("custom-login-policy", {
    // Set this to true to allow users to register themselves.
    allowRegister: true,
    
    // Specify a passwordless login type, such as "WebAuthN" or "Link".
    passwordlessType: "WebAuthN",
    
    // Require users to complete a multi-factor authentication process during login.
    forceMfa: true,

// Specify which multi-factors are allowed for the users.
    multiFactors: ["U2F", "OTP"],
    
    // Optionally, you can set specific second-factors, such as "SMS".
    secondFactors: ["SMS"],

// Set to true if you want to allow external identity providers.
    allowExternalIdp: true,

// Specify any additional options as needed.
});

// To have the login policy take effect, you may need to update your organization's settings or associate the policy with specific resources within ZITADEL.

// Export the ID of the created LoginPolicy as an output of the stack.
export const loginPolicyId = loginPolicy.id;
```

This code creates a login policy tailored to your organization's needs, ensuring that users have a customizable experience while providing a secure environment for them to log in and register. Each property in the `LoginPolicy` is set based on the requirements and features you want to enable.

After running this program with Pulumi, the new login policy will be applied to your ZITADEL organization, and you can manage it as needed through subsequent Pulumi updates or directly in the ZITADEL console.

For more information on the properties and capabilities of the `LoginPolicy` resource, you can refer to the [ZITADEL Pulumi provider documentation](https://www.pulumi.com/registry/packages/zitadel/api-docs/loginpolicy/).
