What is End-to-End Encryption?
End-to-end encryption is a security method that encrypts data on your device and decrypts it only on the recipient's device. This ensures that no one, not even the service provider, can access or intercept your messages, calls, or shared files.
Why Use End-to-End Encryption?
Using E2EE provides:
- Privacy: Keeps your conversations inaccessible to unauthorised parties.
- Security: Protects sensitive data from being exposed or stolen.
- Trust: Ensures confidentiality, even on untrusted networks.
Platforms Offering End-to-End Encryption
Several communication platforms provide E2EE as a standard or optional feature:
- WhatsApp: Default for all chats and calls.
- Signal: Known for prioritising user privacy.
- Zoom: Offers E2EE for meetings when enabled.
- Microsoft Teams: Provides E2EE for one-on-one calls.
How to Enable End-to-End Encryption
- Open the app and navigate to Settings > Privacy.
- Ensure chats are encrypted by default (indicated by a lock icon).
- Verify encryption with contacts by tapping their name, selecting Encryption, and comparing the displayed code.
