# Passwordless Authentication - Per Application

Source: https://apereo.github.io/cas/development/authentication/Passwordless-Authentication-PerApplication.html

Passwordless authentication can be selectively controlled for specific applications. By default, all services and applications are eligible for passwordless authentication.

```json
{
  "@class": "org.apereo.cas.services.CasRegisteredService",
  "serviceId": "^https://app.example.org",
  "name": "App",
  "id": 1,
  "passwordlessPolicy" : {
    "@class" : "org.apereo.cas.services.DefaultRegisteredServicePasswordlessPolicy",
    "enabled": false
  }
}
```

The following passwordless policy settings are supported:

| Name | Description |
| --- | --- |
| `enabled` | Boolean to define whether passwordless authentication is allowed for this service. |
