Mark Zuckerberg has warned Messenger users that one seemingly private habit is no longer discreet, with the platform capable of exposing every dirty deed.
For years, screenshots have offered a discreet way to preserve a chat, allowing users to save everything from important information to more personal exchanges without notifying the person on the other side.
But when disappearing messages enter the conversation, taking a screenshot may no longer go unnoticed.
That extra layer of privacy on Facebook comes with a catch for anyone hoping to quietly preserve something that was intended to vanish.
Vanish Mode
Long before Zuckerberg issued his warning, Meta was already experimenting with conversations that weren’t meant to stick around forever.
In 2020, the company introduced Vanish Mode on Messenger and Instagram, allowing users to send messages that disappeared after they had been viewed and the conversation was closed.
The feature offered an experience already familiar to Snapchat users, but Meta emphasized that people would retain control over whether they wanted to use it.
“We designed Vanish Mode with safety and choice in mind, so you control your experience,” Messenger Product Manager Bridget Pujals and Instagram Product Manager Manik Singh said in a statement, according to USA Today.
Vanish Mode was eventually retired, but Meta didn’t abandon the idea of expiring gab sessions.
Instead, the feature evolved.
Disappearing messages
Facebook now describes disappearing messages as “the same feature” previously offered through Messenger’s Vanish Mode, although users can now set a timer determining when messages automatically disappear, whether they have been read or not.
“People feel more comfortable being themselves when they know their content will only be seen by a smaller group and when their content won’t stick around forever,” Zuckerberg shared in 2018 along with the company’s quarterly results.
But Zuckerberg had been talking about giving users greater control over their privacy long before messages were designed to disappear.
“The way that people think about privacy is changing a bit…What people want isn’t complete privacy. It isn’t that they want secrecy. It’s that they want control over what they share and what they don’t,” the billionaire told Time in 2010.
Years later, disappearing messages gave users one way to exercise that control, but they also created an obvious loophole.
A message could be designed to vanish, but a screenshot could preserve it indefinitely.
And that is where Zuckerberg’s warning comes in.
Screenshot warning
In 2022, Zuckerberg drew attention to another privacy measure for end-to-end encrypted Messenger chats, this time involving screenshots.
“New update for end-to-end encrypted Messenger chats, so you get a notification if someone screenshots a disappearing message,” said the 42-year-old billionaire, who demonstrated the feature through a conversation – and a joke – with his wife, Priscilla Chan.
After Chan captured the exchange, a notification appeared in the conversation revealing that she had taken a screenshot.
The demonstration made the warning clear: messages may be temporary, but attempting to secretly preserve one can alert the other person.
“We think it’s important that you are able to use encrypted chats and feel safe, so we want to keep you informed if anyone takes screenshots of your disappearing messages,” Meta explained.
And while screenshot alerts give users more control over what remains behind after a conversation, Zuckerberg’s ambitions for digital communication extend considerably further than deciding when words should vanish from a screen.
Zuckerberg’s vision beyond the screen
More than two decades after Zuckerberg helped create the social network that became Facebook, the company has expanded far beyond its original social network, bringing Instagram and WhatsApp under the same corporate umbrella before adopting the Meta name.
Zuckerberg has increasingly focused on where digital communication goes next, including artificial intelligence and technology intended to make virtual interactions feel less confined to traditional screens.
In a 2021 chat with The Verge, the father of three questioned why so much of modern life takes place through “small, glowing rectangles.”
“That’s not really how people are made to interact,” he said, explaining that he wants to create a “synchronous environment where we can be together.”
His vision ultimately involves making physical distance far less noticeable during digital interactions.
“The interactions that we have will be a lot richer, they’ll feel real. In the future, instead of just doing this over a phone call, you’ll be able to sit as a hologram on my couch, or I’ll be able to sit as a hologram on your couch, and it’ll actually feel like we’re in the same place, even if we’re in different states or hundreds of miles apart,” Zuckerberg told The Verge.
Just remember that a message may disappear, but if you screenshot it first, your attempt to save it might not stay private.
