Warning

Yandex IoT Core is no longer available to new users.

Current users can create resources until November 1, 2026. Afterwards, the service will go read-only and cease to operate on December 1, 2026. For more information on the timing and procedure, see Service shutdown.

To start exchanging data and commands between devices and registries, you need to authenticate. This section describes how to manage device passwords for the relevant authentication method.

Note

When an X.509 certificate is used along with a password, the password takes priority.

Adding a password to a device

You can add a password to an already created device or set it when creating a device using the --password parameter.

Note

You can also set a password from the input stream by using the --read-password flag instead of --password.

Adding a password to an existing device

Management console

CLI

Terraform

API

To add a password to an existing device:

In the management console, select the folder where you want to add a password to an existing device.
Navigate to IoT Core and select a registry with the device.
Navigate to the Devices tab and select the device.
Under Passwords, click Add password.
In the Password field, enter the password you will use to access the device.
To create a password, you can use this password generator.
Make sure to save the password for later.
Click Add.

If you do not have the Yandex Cloud CLI yet, install and initialize it.

To add a password:

Get a list of devices in the registry:

yc iot device --registry-name my-registry list

Result:

+----------------------+--------+
|          ID          |  NAME  |
+----------------------+--------+
| arenak5ciqss******** | second |
| areqjd6un3af******** | first  |
+----------------------+--------+

Add a password to the device:

yc iot device password add --device-name first --password Passw0rdForDevice

Result:

device_id: areqjd6un3af********
id: areqjd6un3af********
created_at: "2019-12-16T15:11:36.892167Z"

With Terraform, 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. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the guides on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

To manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), authenticate using the appropriate method.

To add a password to a device created with Terraform:

In the configuration file, describe the resource you want to create:
- yandex_iot_core_device: Device properties:
  - registry_id: ID of the registry where the device was created.
  - name: Device name.
  - description: Device description.
  - passwords: List of passwords for username and password authentication.
Here is an example of a resource structure in the configuration file:
```
resource "yandex_iot_core_device" "my_device" {
  registry_id = "<registry_ID>"
  name        = "<device_name>"
  description = "test device for terraform provider documentation"
...
  passwords = [
    "<password>",
  ]
...
}
```
For more on the properties of the yandex_iot_core_device resource, see this provider guide.
In the terminal, navigate to the directory where you edited the configuration file.
Make sure the configuration file is correct using this command:
```
terraform validate
```
If the configuration is valid, you will get this message:
```
Success! The configuration is valid.
```
Run this command:
```
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 detected in the configuration.
Apply the configuration changes:
```
terraform apply
```
Type yes and press Enter to confirm the changes.

You can check device passwords using the management console or this CLI command:
```
yc iot device password list --device-name <device_name>
```

To add a password to a device, use the addPassword REST API method for the Device resource or the DeviceService/AddPassword gRPC API call.

Setting a password for a device when creating it

Management console

CLI

Terraform

API

For information on how to set a password for a device when creating it, see Creating a device.

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder used by default is the one specified when creating 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.

To set a password when creating a device:

Get a list of registries in the folder:

yc iot registry list

Result:

+----------------------+-------------------+
|          ID          |       NAME        |
+----------------------+-------------------+
| arenou2oj4ct******** | my-registry       |
+----------------------+-------------------+

Create a device with a password:

yc iot device create --registry-name my-registry --name device-with-pass --password Passw0rdForDevice

Result:

id: arepomfambsg********
registry_id: arenou2oj4ct********
created_at: "2019-12-16T15:18:39.358922Z"
name: device-with-pass

For information on how to set a password for a device when creating it, see Creating a device.

To set a password for a device when creating it, use the create REST API method for the Device resource or the DeviceService/Create gRPC API call.

resource "yandex_iot_core_device" "my_device" {
  registry_id = "<registry_ID>"
  name        = "<device_name>"
  description = "test device for terraform provider documentation"
