>If need be, send a zipped and encrypted text file and share the password via a voice call. Because people are lazy and not everyone wants to write a file, zip it, encrypt it, call someone, spell the password... Consider sending the password regularly over slack, wait a minute till the other side confirms they got it, and remove the message. Mediocre solutions that people use are better than perfect solutions that everyone circumvents.
