Need to send a password or username to someone like a family member? Don’t do it via email, which (in most cases) isn’t as thoroughly protected from prying eyes as some other communications channels. Encrypted messaging apps such as Telegram or iMessage, or local transfer via something like Apple AirDrop, are preferable.

End-to-end encryption (E2EE) protects your communications during their entire journeys from sender to recipient. Apps like Signal and WhatsApp, as well as the iMessage and FaceTime services on Apple platforms, deploy E2EE to keep your messages private. Defer to E2EE-protected services whenever possible.
