# Security settings

## Restrict access to a board

By default, a board is public, and anyone with the link can access it. You can change this behavior through the security settings.

In certain situations, you may need to restrict access to the board. In these cases, you can limit access by allowing only specific domains, ensuring the board remains private.

### Allowed domains

Instead of adding all stakeholders from your client as individual users, you can simply add "client.com" as allowed domain. This way, anyone with an email ending in "@client.com" will automatically gain access.

If your stakeholder uses subdomains, like "<name@ext.client.com>" for external contractors, they won't automatically gain access until you add the "ext.client.com" as an allowed domain.

### Accessing a restricted board

You can still share a restricted board through the same URL. When accessed by an anonymous visitor, a login prompt will be shown.

Stakeholders will be able to log in through a magic link, only if their domain is added to the allowed domains list. Upon their first visit, an account will be created for them automatically.

If the stakeholder is a Publicboards user, such as yourself, they will be redirected to the default login screen of Publicboards.

## Permissions

You can choose the permissions a visitor has. Everyone who has access to the board has the same permissions.
