/**
 * An account provisioned by a provider has a generated password nobody
 * has ever seen. Until this, that meant it could never have one: the only
 * screen that sets a password asked for the current one first.
 *
 * That was not a cosmetic gap. Enrolling in two-factor is behind a
 * password confirmation, so an installation that makes two-factor
 * compulsory locked out everybody who signs in through a provider — the
 * enforcement middleware sent them to enrol, enrolling sent them to
 * confirm a password they do not have, and every other screen, including
 * the one that would have given them one, redirected back. Reported by
 * Ricardo Cazati.
