Or was that a typo for _million_?\n\nanonymous5344262278:\n\n> But if you are roommates with a doppelgänger, then you may have to adjust your threat model.\n\nI’m not, and neither is the person I’m helping, but still it’s worrisome.\n\nanonymous5344262278:\n\n> As a data point for your actual question though, yah, I think a vast majority of iOS users do use it.
