WhatsApp: Activate and set up encryption
With WhatsApp you can activate secure end-to-end encryption. This protects all messages and WhatsApp calls. There is also a two-factor verification. We'll explain how to set up encryption.
Make WhatsApp secure: How to activate encryption
WhatsApp encryption applies to chats, group chats, WhatsApp calls, pictures and videos, voice messages and file attachments.
- The encryption only works if both chat partners use the latest WhatsApp version. Therefore, check whether an update for WhatsApp is available. If you don't see an update, you can download WhatsApp as an APK from us.
- Then you have to close WhatsApp completely (Android), here you will find our instructions for the iPhone.
- Then open WhatsApp again and tap on the menu button> "Settings".
- Under "Account" you will now find the "Security" section
- Here is a large, green lock symbol that confirms the end-to-end encryption.
Set up WhatsApp encryption
To check if your chat is secure, do the following:
- Open the (group) chat and tap the name at the top.
- Then you will see the menu item "Encryption".
- If there is an open lock next to it, the chat is not encrypted.
- If you tap on the menu entry, you will see the reason for the missing encryption. It is usually because your chat partner has not yet updated WhatsApp (see picture).
- If, on the other hand, the lock is closed, you will be shown a security number with a QR code by tapping "Encryption". This number is identical to the number at your chat partner. A comparison of the numbers confirms the end-to-end encryption.
WhatsApp with two-factor authentication
- Open the "Settings" in the WhatsApp menu and then tap on "Account".
- Select the "Verification in two steps" item and then tap the green "Activate" button.
- Set a six-digit PIN. You must enter this for security reasons, should you reinstall WhatsApp once.
- If you forget your PIN, you can now enter an email address. Tap on "Next" and you will receive a confirmation.
