SN 1008: HOTP and TOTP - SyncThing, Auto-Updates, Sci-Fi Recs

Meta winds down 3rd-party content filtering. Is encryption soon to follow? Taking over abandoned Command & Control server domains (strictly for research purposes only). IoT devices to get the "Cyber Trust Mark" — Will anyone notice or care? "SyncThing" receives a (blessedly infrequent) update. Government email is not using encryption? Really? Email relaying prevents point-to-point end-to-end encryption and authentication. Just because Let's Encrypt doesn't support email doesn't mean it's impossible. What Sci-Fi does ChatGPT think I (Steve) should start reading next? To auto-update or not to auto-update? — is that one question or two? And, until today, we've never taken a deep dive into the technology of time-varying 6-digit one time tokens.
