Multi-Factor Authentication allows users to add an additional layer of protection when logging in to a website, which is ideal for services that tend to be more sensitive or where privacy is paramount. 

At the time of writing, Firebase Auth supports only SMS MFA.

## Enabling Multi-Factor Authentication

Enabling MFA in your Makerkit application requires two steps:

1. You need to upgrade to [Google Cloud Identity Platform](https://cloud.google.com/identity-platform/docs/product-comparison) from the Firebase Console, as it is needed to support MFA
2. Flipping the variable `auth.enableMultiFactorAuth` to `true` in the configuration file, as it is disabled by default

 ```tsx {% title="configuration.ts" %}
auth: {
  // flip this to "true"
  enableMultiFactorAuth: true,
}
```

After enabling MFA, users can set it up from the `Authentication` page at `/settings/authentication`.
