# Authentication

[Catalyst Authentication](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/introduction) is a component of Catalyst Cloud Scale that enables you to add end-users to your application, customize app login and sign-up forms, manage user accounts and roles, and ensure secure access throughout your application.

## Create a New User Instance

You can create a new user instance, and enable the methods defined in this class to access the instance object. This will prevent unnecessary server calls.

You must pass the user's details to the `newUser()` method as shown in the code structure below. You must pass the user's email address and last name mandatorily to create the instance successfully.

```bash
ZCatalystApp.getInstance().newUser( lastName: String, email:String ): ZCatalystUser
```

**Parameters**:
* `lastName`: The last name of the new user
* `email`: Email address of the user, to which the [invitation mail](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/users/implementation/) will be sent

A sample code snippet is shown below:

```bash
val user = ZCatalystApp.getInstance().newUser("Burrows", "emma@zylker.com")
```
