+Changing this variable after that initial setup does **not** update form login behavior in a running instance. To change form login afterward, use [`appsmithctl enable-form-login`](/getting-started/setup/instance-management/appsmithctl#enable-form-login) (alias `appsmithctl efl`) or toggle **Form Login** under **Admin Settings → User Management**, as described in [User Management](/getting-started/setup/instance-configuration/user-management#authentication).
