all kinds of people… lol

in case you didn’t know: it’s relatively easy to write, in just a few lines, a little program to produce the OTP codes on a computer instead of a phone app.

computers can do most of the checking/ordering/sending via websites, and if you live outside of a city those phone-connected infrastructure things don’t exist.

that’s not necessarily what it means. some things legitimately are easier to explain in person. ever try working out a complicated mathematical argument in an email? one can do it, but it’s not pretty. in person you can write on paper, draw figures, etc., synchronously with your compatriot observing and even participating. it’s not merely a change of medium from text to sound.

I don’t read formality in these either, fwiw. in fact they’re generally pretty casual.

ultimately, you will need some kind of access to something with at least one port open, if you intend to host services on the clearnet. you could use tor if onion services will work for you. if you have ssh access somewhere with a port open (or a friendly sysadmin), you could tunnel to there and redirect incoming connections back through the tunnel. same thing with a VPN, if the sysadmin is really friendly.
