Protecting privacy is important to the security of information shared online. So, last year, Meta introduced "end-to-end encryption" in its messaging app to keep users safe. So the messenger adds a special code (code) to the message sent by the sender and sends it to the receiver.

This means that no one else can read the message. Previously this feature was optional, but now Meta has announced that all messages exchanged in Messenger will be automatically encrypted. 

Messenger's end-to-end encryption feature is optional, so many people don't use it or forget to use it. This means that the security of the information exchanged cannot be guaranteed. This is why Meta proactively launched automatic end-to-end encryption.

This means messages from both the Messenger app and Facebook can be exchanged encrypted. At the same time, Meta has begun to open automatic end-to-end encryption capabilities.

The company said all users will get this feature through a Messenger app update. This allows all Facebook and Messenger users to exchange messages securely. Note that end-to-end encryption is essentially a method of secure online communication.

Using this method, the encrypted message is converted back to a plain text message after it reaches the recipient. The information contained in the message cannot be known to anyone except the designated personnel.

Even the application or communication medium that exchanges information cannot understand the information.
