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/) * [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 `updateUserDetails(userID, userDetails)` method. The first name of the user is updated in the example below. The `userManagement` reference used in the code snippet below is the [component instance](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/cloudscale/authentication/get-component-instance/). ```javascript userManagement.updateUserDetails('13749831', { email_id: 'emma@zylker.com', last_name: 'Burrows', zaaid: '1483013413294234', role_id: '843974989234859', first_name: 'Amelia' }); ```
