# `MishkaCmsCore.Accounts.Checks.RegistrationOpen`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core/accounts/__checks/registration_open.ex#L5)

Policy check: passes unless the action would create a new account on a site that is offline.

Put it on the sign-up action, above the bypasses so that it is the first word:

    policy action(:register_with_password) do
      forbid_unless {MishkaCmsCore.Accounts.Checks.RegistrationOpen, []}
      authorize_if always()
    end

Signing in is untouched. A site that is down still has to let its admin back in, so an account that
already exists may authenticate by any means.

## Which site

The changeset's tenant, which `MishkaCmsCore.Runtime.Plugs.SiteLookupPlug` sets from the request's
host. With no tenant the global switch alone decides, so a master who has taken every site offline
also closes registration for anything that reaches this without one.

Who may create an account with no tenant — a master — is asked by
`MishkaCmsCore.Accounts.Validations.MasterUserCreation`, on the action itself.

See `MishkaCmsCore.Settings.offline?/1`.
