# Getting Started with Users

The how-to guides linked on this page illustrate how to register your users with Immuta.

Use one of the options below to register your users in Immuta:

1. [Configure an external identity manager](#configure-an-iam).
2. [Manually register users](#manually-create-users).

## [Configure an IAM](https://documentation.immuta.com/saas/configuration/people/section-contents)

[External identity managers](https://documentation.immuta.com/saas/configuration/people/section-contents/reference-guides/index) configured in Immuta allow users to authenticate using an existing identity management system and can optionally be used to synchronize user groups and attributes into Immuta.

1. [Configure your IAM](https://documentation.immuta.com/saas/application-configuration/how-to-guides/config-builder-guide#use-existing-identity-access-manager).
2. [Ensure the user IDs are mapped from the integration they will use to Immuta](https://documentation.immuta.com/saas/configuration/people/users-index/how-to-guides/external-user-mapping).
3. [Manage user permissions](https://documentation.immuta.com/saas/configuration/users-index/how-to-guides/managing-personas-and-permissions#add-permission-to-user).

1. [Create the users in Immuta](https://documentation.immuta.com/saas/configuration/people/users-index/how-to-guides/managing-personas-and-permissions).
