Security in Superset is handled by Flask AppBuilder (FAB). FAB is a “Simple and rapid application development framework, built on top of Flask.”. FAB provides authentication, user management, permissions and roles.

Provided Roles

Superset ships with a set of roles that are handled by Superset itself. You can assume that these roles will stay up-to-date as Superset evolves. Even though it’s possible for Admin usrs to do so, it is not recommended that you alter these roles in any way by removing or adding permissions to them as these roles will be re-synchronized to their original values as you run your next superset init command.

Since it’s not recommended to alter the roles described here, it’s right to assume that your security strategy should be to compose user access based on these base roles and roles that you create. For instance you could create a role Financial Analyst that would be made of set of permissions to a set of data sources (tables) and/or databases. Users would then be granted Gamma, Financial Analyst, and perhaps sql_lab.


Admins have all possible rights, including granting or revoking rights from other users and altering other people’s slices and dashboards.


Alpha have access to all data sources, but they cannot grant or revoke access from other users. They are also limited to altering the objects that they own. Alpha users can add and alter data sources.


Gamma have limited access. They can only consume data coming from data sources they have been giving access to through another complementary role. They only have access to view the slices and dashboards made from data sources that they have access to. Currently Gamma users are not able to alter or add data sources. We assume that they are mostly content consumers, though they can create slices and dashboards.

Also note that when Gamma users look at the dashboards and slices list view, they will only see the objects that they have access to.


The sql_lab role grants access to SQL Lab. Note that while Admin users have access to all databases by default, both Alpha and Gamma users need to be given access on a per database basis.

Managing Gamma per data source access

Here’s how to provide users access to only specific datasets. First make sure the users with limited access have [only] the Gamma role assigned to them. Second, create a new role (Menu -> Security -> List Roles) and click the + sign.


This new window allows you to give this new role a name, attribute it to users and select the tables in the Permissions dropdown. To select the data sources you want to associate with this role, simply click in the dropdown and use the typeahead to search for your table names.

You can then confirm with your Gamma users that they see the objects (dashboards and slices) associated with the tables related to their roles.


The permissions exposed by FAB are very granular and allow for a great level of customization. FAB creates many permissions automagically for each model that is create (can_add, can_delete, can_show, can_edit, ...) as well as for each view. On top of that, Superset can expose more granular permissions like all_datasource_access.

We do not recommend altering the 3 base roles as there are a set of assumptions that Superset build upon. It is possible though for you to create your own roles, and union them to existing ones.


Roles are composed of a set of permissions, and Superset has many categories of permissions. Here are the different categories of permissions:

  • Model & action: models are entities like Dashboard, Slice, or User. Each model has a fixed set of permissions, like can_edit, can_show, can_delete, can_list, can_add, and so on. By adding can_delete on Dashboard to a role, and granting that role to a user, this user will be able to delete dashboards.
  • Views: views are individual web pages, like the explore view or the SQL Lab view. When granted to a user, he/she will see that view in the its menu items, and be able to load that page.
  • Data source: For each data source, a permission is created. If the user does not have the all_datasource_access permission granted, the user will only be able to see Slices or explore the data sources that are granted to them
  • Database: Granting access to a database allows for the user to access all data sources within that database, and will enable the user to query that database in SQL Lab, provided that the SQL Lab specific permission have been granted to the user

Restricting access to a subset of data sources

The best way to go is probably to give user Gamma plus one or many other roles that would add access to specific data sources. We recommend that you create individual roles for each access profile. Say people in your finance department might have access to a set of databases and data sources, and these permissions can be consolidated in a single role. Users with this profile then need to be attributed Gamma as a foundation to the models and views they can access, and that Finance role that is a collection of permissions to data objects.

One user can have many roles, so a finance executive could be granted Gamma, Finance, and perhaps another Executive role that gather a set of data sources that power dashboards only made available to executives. When looking at its dashboard list, this user will only see the list of dashboards it has access to, based on the roles and permissions that were attributed.

Restricting the access to some metrics

Sometimes some metrics are relatively sensitive (e.g. revenue). We may want to restrict those metrics to only a few roles. For example, assumed there is a metric [cluster1].[datasource1].[revenue] and only Admin users are allowed to see it. Here’s how to restrict the access.

  1. Edit the datasource (Menu -> Source -> Druid datasources -> edit the record "datasource1") and go to the tab List Druid Metric. Check the checkbox Is Restricted in the row of the metric revenue.
  2. Edit the role (Menu -> Security -> List Roles -> edit the record “Admin”), in the permissions field, type-and-search the permission metric access on [cluster1].[datasource1].[revenue] (id: 1), then click the Save button on the bottom of the page.

Any users without the permission will see the error message Access to the metrics denied: revenue (Status: 500) in the slices. It also happens when the user wants to access a post-aggregation metric that is dependent on revenue.
