Why making a call with Facebook is safer than ever

Facebook already uses end-to-end encryption for calls

From Facebook they have announced the novelty of implementing end-to-end encryption when performing voice or video calls from Messenger. Keep in mind that this has already been applied to written chats for years. That is, until now text conversations were end-to-end encrypted and from now on, calls and video calls will also be encrypted.

Other applications to carry out this type of communication had already been advanced and had end-to-end encryption. For example we can name Zoom or Microsoft Teams in individual calls. Now we can also use it in the call service of the popular social network.

The messaging application of the famous social network thus joins the main ones that already implemented this system also when making any voice or video call. At the end of the day, not only the text we send can be intercepted, but also any call we make. This can happen if for example we use a insecure public network.

How End-to-End Encryption Works

Now, how does end-to-end encryption work and how does it really protect us? It is also known as E2EE and what it basically does is apply an encryption to the text we send or receive, as well as to the voice or video calls we make. This encryption allows only the device to which we are sending that message to be able to decrypt it.

Let’s say we are using an application to send a text message. The same could apply if we are going to make a call from Facebook, with this novelty. Our message or audio will encrypt and it will travel to the destination device, which will decrypt it and deliver it to the other person with whom we are talking or who is going to read a message. Along the way, even if there were an intruder to intercept that communication, it could not be read or heard as it was encrypted.

With this we guarantee that only users involved in a communication they can read that text or listen to that call we are making. This system is based on keys that are only known by the parties that communicate with each other. Mainly it protects us from Man in the Middle attacks.

Automatically deleted messages

Another novelty that Facebook also includes is being able to configure the automatic deletion of messages. This is also linked to security and privacy. We can choose that the messages we send are automatically deleted after a while.

The time is variable, but we can put it from just 5 seconds to a day. This prevents someone with access to the terminal from being able to read what we have sent or received. One more way to improve privacy and avoid problems.

Therefore, from now on use Facebook Messenger to make any voice or video call will be more secure. They finally apply end-to-end encryption, which is a demand that many users have been making for a long time so that it can be compared to other similar applications.
