The WhatsApp beta for iOS 23.9.0.70 update on the TestFlight app is necessary to use the functionality. However, only a small number of beta testers have access to the feature right now.
WhatsApp's three-month-long campaign highlights simple-yet-effective ways to enable WhatsApp safety features and focuses on the importance of safeguarding users’ accounts.
As per a report by WaBetaInfo, WhatsApp is working on a new feature which will allow users to lock chats using a passcode or fingerprint. This will enhance the privacy of users by avoiding the risk of confidential and sensitive information being leaked.
This new feature will improve the users' privacy as it will help users to lock their most private chats within the chat's contact or group info, reports WABetaInfo.
