>>>>>Why are you saying that text isn't secure? IIRC, the FBI was asking Apple to help getting messages from the San Bernardino terrorist's cell phone because they could not get in any other way.
>>>Apple stores txts securely, but I'm referring to the transmission which a hacker would have to intercept. You can intercept sms traffic easily enough and if you can get close enough to your target to lift the TMSI, encryption can be trivial. In this case this theoretical exploit doesn't matter because unless you're under serious surveillance, few hackers can reliably snoop both a momentary sms transfer and your email- especially if they're in Russia or wherever. Sorry if not clear- I meant to say that even if paranoia says txt isn't secure, it's a different vector so increases hack protection hugely.

I did. But I was looking for more of a "routine" approach that would minimize my kid's time. I already gave her my password to my dropbox. Ideally I would like to place a zip file in a certain folder of the dropbox, whenever any of my personal data is changed. Provided, that she can open this zip file and extract the data, if ever necessary, she does not need to do anything. Just know that it is there. Hopefully she will take the time to try my test zip I sent her yesterday.
Thank you for your suggestion.
