Description

An end-to-end encrypted messaging service owned by Facebook. WhatsApp is widely used across the globe, therefore many contacts will already be users on the app.

Notes

Approximate Cost
WhatsApp is completely free — with no fees or subscriptions — because it uses your phone's 5G, 4G, 3G, 2G, EDGE, or Wi-Fi connection instead of your cell plan's voice minutes or text plan

Cybersecurity Considerations
WhatsApp messages and calls are end-to-end encrypted, but the app does not protect metadata. There is a feature that allows users to back messages up to a cloud-based server; NDI strongly recommends disabling this feature as it essentially undos the benefits of end-to-end encryption since cloud servers are subject to security breaches such as hacking.
