WhatsApp adds hidden tricks for disappearing messages, chat locks and editing
Popsci outlines three lesser‑known features that let users control privacy and correct mistakes on WhatsApp.
By Felo News Desk · Published
WhatsApp, used by an estimated three billion people each month, includes several privacy‑focused tools that many users overlook, Popsci reported on Oct. 17.
What happened
The guide explains how to activate a timer that automatically removes messages after 24 hours, seven days or ninety days. The setting is applied per chat and affects all participants, but it does not erase the conversation history before the timer starts.
It also shows how to add a lock to individual conversations. On Android, users tap the chat name, select “Chat lock,” and set a PIN; on iOS, the option appears as “Lock chat” and can use Face ID or a PIN. Locked chats remain hidden even if the phone itself is unlocked.
Finally, the article details the message‑editing feature. After sending a message, a long‑press and selection of “Edit” (Android) or tapping “Edit” from the pop‑up menu (iOS) lets users modify the text. Edited messages display an “Edited” label, but the original content is not shown to participants.
What the reports add
Popsci notes that the disappearing‑message timer can be changed at any time and remains active until the user disables it or selects a different period. The chat‑lock feature works on a per‑conversation basis, meaning users can protect only the most sensitive chats while leaving others freely accessible.
The editing function, introduced in recent updates, applies to both Android and iOS versions, and the “Edited” tag is visible to everyone in the chat, ensuring transparency about changes.
What was said
David Nield, quoted in the Popsci piece, describes the chat‑lock as “another way of protecting sensitive information in chats” and explains that the lock uses the same biometric technology that secures the phone’s lock screen.
How it came about
WhatsApp’s suite of privacy tools has expanded as the platform’s user base grew to billions worldwide. While the article does not link to prior Felo coverage, the rise of messaging‑app privacy features aligns with recent technology reporting on device‑level security enhancements.
