End-to-end encryption is a system of communication where messages are encrypted on your device and not decrypted until they reach the intended recipient. This ensures that your message cannot be read if it is intercepted by a cyber criminal. Platforms such as WhatsApp, iMessage and Android Messages are end-to-end encrypted. Facebook Messenger is not currently end-to-end encrypted.

Enable security settings, including contact verification, security notifications, and encryption. Disable optional non-security features such as read receipt, last online, and typing notification.

Your conversations aren't secure if the person you're speaking to isn't in a secure place. Before sending anything sensitive, ask your recipient if they are in a safe place to recieve important personal information. If they are not, then wait until they are.
