My accountant asked me to send tax documents. My parents needed help with medical records. A client wanted API credentials. Every time I hit the same problem: PGP is way too complex for them, Signal requires installing an app, email attachments feel insecure, and I don't trust random file sharing sites.
What do you all actually use in practice? Curious if there's something obvious, I'm missing.
For actually sending, Signal disappearing messages or phone calls for some info.
