Recently, Meta, the parent company of Facebook Messenger, has been testing an end-to-end encryption system and giving users the option to turn it on or off. It's like giving users a chance to decide for themselves whether they want to wear a "talisman" when it comes to protecting their privacy and security.
Text editing features.
When the system is activated, it's like pulling up a soundproof door, only the sound between you and the recipient is allowed to come out, and other outside noise is kept out. However, you can still edit messages you've already sent, or easily hide them to protect your privacy. In addition, some other features, such as voice messages, will be limited to a maximum retention period of 15 minutes to ensure that your information is stored for a long time.
Hide messages and send as needed feature.
As for quality, Facebook Messenger announced that it will be testing HD resolution to improve the quality of its still image transfer features. This news is like a fresh spring breeze, blowing away people's troubles about ambiguity, so that everyone can feel every detail more clearly and truly when sharing beautiful moments.
