Mark Zuckerberg has issued a new warning to Facebook Messenger users, urging them to think carefully before taking screenshots of private conversations. His message drew attention because it reflects Meta’s continued push toward stronger privacy tools and user control. Zuckerberg, who co-founded Facebook at Harvard and now leads Meta as its chairman and CEO, has long been a central figure in discussions about online privacy.

Recently, he reminded users of an important Messenger update delivered with a light tone but a serious message. Screenshots of disappearing messages will no longer be invisible. From now on, users will receive automatic alerts when someone captures an image of a chat meant to vanish.
This update ties back to Vanish Mode, launched in 2020 across Messenger and Instagram. Vanish Mode allowed people to send temporary messages that disappeared once viewed and the chat was closed. It was designed for spontaneous conversations—moments people wanted to share freely without leaving a long-term digital trail.
Activating Vanish Mode was simple: swiping up in any chat turned it on, and swiping again turned it off. It debuted in the United States before expanding across parts of Europe. Messenger Product Manager Bridget Pujals and Instagram’s Manik Singh explained at the time that the feature centered on safety and user choice, giving people more control over how long their messages lasted.
However, the Facebook Help Center now notes that Vanish Mode is no longer supported. Meta is slowly replacing it with a new system called disappearing messages. Not everyone has access yet, but those who do can find the setting under Privacy and Support within any chat.
Disappearing messages keep the same purpose but add clearer safeguards. If someone takes a screenshot or begins screen recording, a notification appears instantly. This ensures users know when temporary messages are being saved.
Zuckerberg even demonstrated the feature in a playful chat with his wife, Priscilla Chan. Her screenshot triggered an immediate alert, showing the new system in action. It’s all part of Meta’s ongoing effort to make digital communication more private, transparent, and user-controlled.
