/**
 * Returns the lowest password quality that still presents the same UI for entering it.
 *
 * For the FRP credential, we do not want to leak the actual quality of the password, only what
 * kind of UI it requires. However, when migrating, we only know the actual quality, not the
 * originally requested quality; since this is only used to determine what input variant to
 * present to the user, we just assume the lowest possible quality was requested.
