# Configuring access permissions for a certificate

To grant an individual user, user group, or [service account](../../iam/concepts/users/service-accounts.md) access to a [certificate](../concepts/index.md#types), assign a [role](../../iam/concepts/access-control/roles.md) for it.

## Assigning a role {#access-to-user}

{% list tabs group=instructions %}

- CLI {#cli}

  If you do not have the Yandex Cloud CLI yet, [install and initialize it](../../cli/quickstart.md#install).

  The folder used by default is the one specified when [creating](../../cli/operations/profile/profile-create.md) the CLI profile. To change the default folder, use the `yc config set folder-id <folder_ID>` command. You can also specify a different folder for any command using `--folder-name` or `--folder-id`. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

  1. View the description of the CLI command for assigning a role for a certificate:

      ```bash
      yc certificate-manager certificate add-access-binding --help
      ```

  1. Get the list of certificates in the default [folder](../../resource-manager/concepts/resources-hierarchy.md#folder):

      ```bash
      yc certificate-manager certificate list
      ```

      Result:

      ```text
      +----------------------+--------+-------------+---------------------+----------+---------+
      |          ID          |  NAME  |   DOMAINS   |      NOT AFTER      |   TYPE   | STATUS  |
      +----------------------+--------+-------------+---------------------+----------+---------+
      | fpqgbg3fajpg******** | cert-1 | example.com | 2026-01-04 13:58:14 | IMPORTED | ISSUED  |
      | fpqlhev2j4ad******** | cert-2 | example.com | 2026-01-04 14:07:02 | IMPORTED | ISSUED  |
      +----------------------+--------+-------------+---------------------+----------+---------+
      ```

  1. Check what roles are currently assigned for the resource in question:

      ```bash
      yc certificate-manager certificate list-access-bindings <certificate_ID>
      ```

  1. Assign the role using this command:

      * To a user:

          ```bash
          yc certificate-manager certificate add-access-binding <certificate_ID> \
            --user-account-id <user_ID> \
            --role <role>
          ```

          Where:

          * `--user-account-id`: [User ID](../../organization/operations/users-get.md).
          * `--role`: [Role](../security/index.md#roles-list) to assign.

      * To a service account:

          ```bash
          yc certificate-manager certificate add-access-binding <certificate_ID> \
            --service-account-id <service_account_ID> \
            --role <role>
          ```

          Where:

          * `--service-account-id`: [Service account ID](../../iam/operations/sa/get-id.md).
          * `--role`: Role to assign.

- Terraform {#tf}

  With [Terraform](https://www.terraform.io/), you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.
  
  Terraform is distributed under the [Business Source License](https://github.com/hashicorp/terraform/blob/main/LICENSE). The [Yandex Cloud provider for Terraform](https://github.com/yandex-cloud/terraform-provider-yandex) is distributed under the [MPL-2.0](https://www.mozilla.org/en-US/MPL/2.0/) license.
  
  For more information about the provider resources, see the guides on the [Terraform](https://www.terraform.io/docs/providers/yandex/index.html) website or [its mirror](../../terraform/index.md).

  If you do not have Terraform yet, [install it and configure the Yandex Cloud provider](../../tutorials/infrastructure-management/terraform-quickstart.md#install-terraform).
  
  
  To manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), [authenticate](../../terraform/authentication.md) using the appropriate method.

  To assign a role for a certificate using Terraform:

  1. In the Terraform configuration file, describe the resources you want to create:

      ```hcl
      resource "yandex_cm_certificate_iam_member" "mycert-roles" {
        certificate_id = "<certificate_ID>"
        role           = "<role>"
        member         = "<subject_type>:<subject_ID>"
      }
      ```

      Where:

      * `certificate_id`: Certificate ID.
      * `role`: [Role](../security/index.md#roles-list) to assign.
      * `member`: Type and ID of the [subject](../../iam/concepts/access-control/index.md#subject) the role is assigned to. Specify it as `userAccount:<user_ID>` or `serviceAccount:<service_account_ID>`.

       For more information about the `yandex_cm_certificate_iam_member` resource properties, see [this provider guide](../../terraform/resources/cm_certificate_iam_member.md).

  1. Create the resources:

      1. In the terminal, navigate to the configuration file directory.
      1. Make sure the configuration is correct using this command:
      
         ```bash
         terraform validate
         ```
      
         If the configuration is valid, you will get this message:
      
         ```bash
         Success! The configuration is valid.
         ```
      
      1. Run this command:
      
         ```bash
         terraform plan
         ```
      
         You will see a list of resources and their properties. No changes will be made at this step. Terraform will show any errors in the configuration.
      1. Apply the configuration changes:
      
         ```bash
         terraform apply
         ```
      
      1. Type `yes` and press **Enter** to confirm the changes.

      Terraform will create all the required resources. You can check the new resources using this [CLI](../../cli/index.md) command:

      ```bash
      yc certificate-manager certificate list-access-bindings <certificate_ID>
      ```

- API {#api}

  Use the [updateAccessBindings](../api-ref/Certificate/updateAccessBindings.md) REST API method for the [Certificate](../api-ref/Certificate/index.md) resource or the [CertificateService/UpdateAccessBindings](../api-ref/grpc/Certificate/updateAccessBindings.md) gRPC API call. In the request body, set the `action` property to `ADD` and specify the user type and ID under `subject`.

- CLI {#cli}

  If you do not have the Yandex Cloud CLI yet, [install and initialize it](../../cli/quickstart.md#install).

  The folder used by default is the one specified when [creating](../../cli/operations/profile/profile-create.md) the CLI profile. To change the default folder, use the `yc config set folder-id <folder_ID>` command. You can also specify a different folder for any command using `--folder-name` or `--folder-id`. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

  You can assign multiple roles using the `set-access-bindings` command.

  {% note alert %}
  
  The `set-access-bindings` command completely rewrites access permissions for the resource. All current roles for the resource will be deleted.
  
  {% endnote %}

  1. View the list of roles assigned for a certificate:

      ```bash
      yc certificate-manager certificate list-access-bindings <certificate_ID>
      ```

      If you need to save the roles, specify them in the command for assigning roles.

  1. View the description of the CLI command for assigning roles for a certificate:

      ```bash
      yc certificate-manager certificate set-access-bindings --help
      ```

  1. Assign the roles:

      ```bash
      yc certificate-manager certificate set-access-bindings <certificate_ID> \
        --access-binding role=<role>,subject=<subject_type>:<subject_ID>
      ```

      Where:

      * `--access-binding`: Role to assign:
          * `role`: ID of the role to assign.
          * `subject`: Type and ID of the [subject](../../iam/concepts/access-control/index.md#subject) the role is assigned to.

      For example, this command will assign roles to multiple users and a single service account:

      ```bash
      yc certificate-manager certificate set-access-bindings my-certificate \
        --access-binding role=editor,subject=userAccount:gfei8n54hmfh********
        --access-binding role=viewer,subject=userAccount:helj89sfj80a********
