By default, boards are open to everyone within a project. For boards that use multiple projects, this means the board is open to everyone in all the projects the board it tied to.

You can change the board permissions by editing the board, and navigating to the Permissions screen.

Wizard projects

From here, you can mark a board as private, in which case only the creator of the board has access to it, or you can change the board to only be shared with a specific set of groups.

Wizard projects

In this case, only members of the selected groups can see/interact with the board.

CAN I RESTRICT WHAT USERS CAN DO IN A BOARD?

At the moment, permissions are not that granular. Anyone with access to the board can see it, move issues, edit the board, or even delete it. In the future, we will be adding more granular permissions to provide ways to lock down a board and decide what kind of actions users can take.
