I'd like to do this in theory, but practically I find it not worth it. Consider a case where your partner or your kid lose their phone, are stranded, and borrow a phone from someone. They won't reach you.

They'd know to send a text or email.

Ask to borrow a stranger's phone to get in touch with someone.

Watch their terror as you open their text or email app and get snippets of their private communications.

I'm not sure about your plan, tbh.
