# Update Details of a User

Catalyst allows you to [modify and update](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/users/implementation/#modify-a-users-details) the following details of an end-user:

* First Name
* Last name
* [`ZAAID`](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/users/introduction/): `ZAAID` or Org ID, is a unique value that is generated by Catalyst to associate with an organization.
* [RoleID](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/roles/implementation/): Role ID is the value generated by Catalyst that is assigned to a particular [user role](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/roles/introduction/).

The SDK snippet below demonstrates updating an end-user's details using the `updateUser()` method. The first name of the user is updated in the example below.

The `getUserID()` method will fetch the [User ID](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/users/introduction/) of the user. The UserID will be present in the *Users* > *User Management* section of the Authentication component.

#### Sample Code Snippet

**Package Imports**

```java
import com.zc.component.ZCUserDetail; 
import com.zc.component.users.ZCUser;

```

```java
ZCUser user = ZCUser.getInstance();
ZCUserDetail userDetail = user.getCurrentUser();
userDetail.setFirstName("Josh");
user.updateUser(userDetail.getUserId(), userDetail);

```
