# Users and access management


### Does DataLens support login via SSO? {#sso-in-datalens}

In Yandex DataLens, you can [configure authentication](../security/add-new-user.md#federated-user) using SSO or [identity federation](../../organization/concepts/add-federation.md), if you have one. DataLens users can get authenticated using their corporate accounts.


### How do I add a user and send them a link to the dashboard? {#how-add-user-send-ref}

To allow another user to open your dashboard, configure access to Yandex DataLens:

1. [Invite a user](../../organization/operations/add-account.md#send-invitation) with a Yandex account or add a [federated](../../organization/operations/add-account.md#add-user-sso) or [local](../../organization/operations/add-account.md#local) user.
1. Make sure the user has access permissions to the dashboard:

   1. Open the dashboard.
   1. In the **Add member** field, enter _All_ or the name of the user who needs extended permissions.
   1. Go to the **Current object** section and set the permissions for the dashboard:

      * View: Read only is available.
      * Edit: View and edit options are available.
      * Administration: View, edit, and manage options are available.

   1. Enable the **Linked objects** option to grant permissions to other dashboard-related objects, such as connections, dashboards, and charts.

The user is granted access to your DataLens and objects with **All** permissions. You can assign this user individual permissions to objects.

You can send the link to the dashboard from the browser. For more information about permissions to DataLens objects, see the [documentation](../security/index.md#permissions).

You can also make your dashboard public using [Public access](../concepts/datalens-public.md).

### Why do I get a permission error? {#permission-error}


To fix the error, check the following:

* The user was assigned the `datalens.visitor` role in the [organization](../concepts/organizations.md) to access DataLens in it.
* The user was granted the required [permissions to the workbook](../workbooks-collections/workbooks-operations.md#security) that contains the current object and its related objects.
* If you are using the old folder navigation, check the [access permissions to the object](../security/manage-access.md). You can assign access permissions to all your users using the **All** group.

For more information about permissions to DataLens objects, see the [relevant guide](../security/index.md).

### What permissions does an object copied to a folder get? {#copy-into-folder}

If you copy an object to a folder, it gets the same permissions as the folder. For more information about configuring permissions, see [these guides](../security/index.md).

### How do I revoke a Yandex account access token? {#revoke-token}

You can disable access to account data at any time by revoking a Yandex ID token:

1. Open [Yandex ID](https://passport.yandex.com).
1. Go to **Logins and devices** → **Devices, services, and applications**.
1. Under **Other applications and services**, select DataLens.
1. Click **Delete**.

Once the token is revoked, any connections using it will stop working (see [this error description](../troubleshooting/errors/ERR-DS_API-SOURCE_ACCESS_DENIED-INVALID_TOKEN.md)).
