Communications & social presence

Secure the channel and the public presence: encrypted messaging, identity checks, privacy settings, and account takeover.

What end-to-end encryption really protects, and how Signal, WhatsApp & Telegram differ.

Out-of-band checks that defeat cloned profiles and the "Hi Mum" scam.

A per-platform pass through the privacy settings that actually matter.

How small, harmless-seeming details add up — and how to share without giving them away.

Search yourself the way a stranger would, and split your professional and private presence.

The warning signs, the rogue forwarding rule, and the correct recovery order.

Revoke forgotten app grants and stale sessions — the keys a new password doesn't touch.
