I promise they have win+iOS. iMessage is the only reason that I have an iPhone. Well, that and the inability for any other messaging service to provide reliable real-time messaging with read receipts (both critical for core-family safety reasons; friends and work colleagues get my GVoice number which, ironically, worked better on iOS than Android at the time I switched).

As a bonus, my F-I-L currently uses the Notes app as his vault (not the secure version, just a note entitled "Passwords") and my mother uses a combination of several slips of paper floating about her office, Google Chrome's internal password memory system, and a system involving her dog's name, a site identifier, and the last four digits of a phone number she had as a child. That last one is pretty good, except that the old bird is really bad at remembering which letters she capitalizes and which part of the URL she's going t use as the identifier, so some sites are just easier for her to get a password reset every time she uses them. I'm actually getting jittery just thinking about it.

advising people to use google products? is that the new edgelord thing?

Yeah, local only will kill ease of assistance.
