WhatsApp, soon the chats to be unlocked with the fingerprint: how they will work

News coming for WhatsApp. According to what WaBetaInfo reveals in a tweet, they are working on some chats that can only be unlocked with a fingerprint. The function can be activated both for single contacts and for groups, directly from the main bar by clicking on ‘Chat lock’. An extra layer of privacy with photos and videos that wouldn’t automatically save to galleries like today.
