# Managing Credentials

An ACS generally uses digital means of access to authorize an [ACS user](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/access-systems/user-management) trying to get through a specific entrance. Examples of credentials include plastic key cards, mobile keys, biometric identifiers, and PIN codes. The electronic nature of these credentials, as well as the fact that access is centralized, enables both the rapid provisioning and rescinding of access and the ability to compile access audit logs.

This guide provides instructions for creating and deleting various types of credentials.

{% hint style="info" %}
You can assign a credential to an ACS user when you create the credential. You can also [assign an existing credential to an ACS user](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/access-systems/assigning-credentials-to-users#assign-a-credential-to-a-user). Further, you can [unassign a credential from an ACS user](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/access-systems/assigning-credentials-to-users#unassign-a-credential-from-a-user) without deleting the credential.

## Create a Credential for an ACS User

To [create a credential for an ACS user](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/api/acs/credentials/create), provide the `acs_user_id` and the desired `access_method`. Seam supports the following access methods:

* `code` for a PIN code-based credential
* `card` for a plastic key card-based credential
* `mobile_key` for a [Seam mobile key](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/mobile-access/issuing-mobile-credentials-from-an-access-control-system#what-are-multi-phone-sync-credentials).

Depending on the ACS and the type of credential you are issuing, you can also specify the following properties for the new credential:

* PIN code.
* Start and end time frame for the validity of the credential.
* Whether the credential is a multi-phone sync credential.\
  When creating a Seam mobile key, make sure to issue a multi-phone sync credential by setting `is_multi_phone_sync_credential` to `true`.
* Manufacturer-specific data.

{% hint style="info" %}
Make sure to note any manufacturer-specific metadata and restrictions. For details, see the applicable [device or system integration guide](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/device-and-system-integration-guides/overview).
{% endhint %}

The response includes the `acs_credential_id` of the newly-created credential, the `acs_user_id` associated with the credential, and additional attributes of the credential.

{% hint style="info" %}
If you are creating card-based credentials, and your ACS requires card encoding, see also [Creating and Encoding Card-based Credentials](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/access-systems/working-with-card-encoders-and-scanners/creating-and-encoding-card-based-credentials).

### Create a Card-based Credential

To create a plastic key card-based credential, set the `access_method` to `card`. Once you've created a credential, some access control systems require you to encode the card with the credential. To learn whether your ACS requires card encoding, see the [system integration guide](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/device-and-system-integration-guides/overview#access-control-systems) for your ACS. For card encoding instructions, see [Creating and Encoding Card-based Credentials](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/access-systems/working-with-card-encoders-and-scanners/creating-and-encoding-card-based-credentials).

### Create a Seam Mobile Key

Depending on the ACS for which you want to create a credential, you may also need to include system-specific metadata. See the [system integration guide](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/device-and-system-integration-guides/overview#access-control-systems) for your ACS. For more information about mobile access and issuing mobile credentials, see [Mobile Access](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/mobile-access) and [Issuing Mobile Credentials from an Access Control System](https://docs.seam.co/latest/~/revisions/DFdrUdS2jQOnbJTNDT5a/capability-guides/mobile-access/issuing-mobile-credentials-from-an-access-control-system).
