Automatic user provisioning
With automatic user provisioning enabled, Portainer will create user(s) automatically with standard user role. If disabled, users must be created beforehand in Portainer in order to login.

The users created by the automatic provisioning feature can be added to a default team on creation.

By assigning newly created users to a team they will be able to access the environments associated to that team. This setting is optional and if not set newly created users won't be able to access any environments.

You have not yet created any team. Head over the teams view to manage user teams.
