Nowadays, people tend to pay more attention to privacy and security protection. Therefore, in order to meet the requirements of customers, application developers always try their best to improve the security of their products. And WhatsApp is doing the same thing. If you have downloaded and used the latest WhatsApp version, you must know that it equips a new feature- end-to-end encryption, which is used to protect the privacy of users and the security of the data.
When you first get a new feature of a program, the most primary thing you need to do is to know what it is. The end-to-end encryption is a communication system which only allows the communicating users to read the messages. With it, any other third-parties are unable to access the data like messages, photos, videos, etc. on WhatsApp, including telecom providers, Internet providers and even the developer of WhatsApp. It will help you get rid of the annoyance about information disclosure.
After knowing its function, you might wonder how to enable the end-to-end encryption in WhatsApp. It is very simple! To enjoy this feature, you only need to do nothing but download and install the latest WhatsApp on your phone for the reason that it is a auto-feature. But it also means that you are not able to turn off the feature. And meanwhile, please notice that the receiver of the messages you sent must install the latest application version as well. Otherwise, the feature will not work and your conversation might be revealed.
We have mentioned that the end-to-end encryption in WhatsApp is a auto-feature and we cannot do anything to enable it, but how can we know whether our chats are protected? Don't worry! There is a method to verify it. You can go with the steps listed below to check it.
