How to enable end-to-end encryption on your WhatsApp phone - in detail?

To enable end-to-end encryption on your WhatsApp phone, follow these detailed steps:

Update Your App: Ensure that both you and the person you're communicating with have the latest version of WhatsApp installed. End-to-end encryption is only available in the most recent versions of the app. You can update WhatsApp from the Google Play Store or Apple App Store.
Verify Your Contact: Before starting a conversation, verify that your contact's number is up to date and that you have saved their contact information on your phone. This ensures that the encryption process works correctly.
Start a New Conversation: Open WhatsApp and start a new chat with the person you want to communicate with securely. You can do this by tapping on the 'New Chat' icon and selecting the contact from your list.
Check for Encryption: Once the conversation starts, look at the top of the chat window. You should see a message indicating that messages and calls are end-to-end encrypted. This message will say something like "Messages and calls are now secured with end-to-end encryption."
Verify Encryption (Optional): If you want to ensure that your conversation is indeed encrypted, both parties can compare a unique security code. To do this:
- Tap on the contact's name at the top of the chat window.
- Select 'Encryption' from the menu.
- You will see a 60-digit number. This is your security code.
- Ask the other person to do the same and compare the codes. If they match, your messages are end-to-end encrypted.

By following these steps, you can ensure that your WhatsApp conversations are protected by end-to-end encryption, providing a high level of security for your communications.
