# Assigning Credentials to ACS Users

This guide explains how to assign existing [credentials](https://github.com/seamapi/docs/blob/main/docs/guides/capability-guides/access-systems/managing-credentials/README.md) to [ACS users](/latest/capability-guides/access-systems/user-management.md) and unassign credentials from users. Once you assign credentials to ACS users, these users can use the credentials to access areas and resources according to their permissions. When you unassign credentials from ACS users, these users can no longer use these specific credentials to access areas or resources.

***

## Assign a Credential to an ACS User

To [assign a credential to an ACS user](https://docs.seam.co/latest/api/acs/credentials/assign), provide both the `acs_user_id` and the `acs_credential_id`.
