WhatsApp is reportedly developing a new feature that comes with several privacy benefits for its Android application.
According to a WhatsApp tracker, the new feature, dubbed “Username keys,” has two parts. The first part is the username itself, which is said to replace the need to share one's number when sharing their WhatsApp account.
Meanwhile, the second is Username keys, which are said to let users manage whether a first-time texter can contact the user or not.
WhatsApp to launch Username Keys, expanding Meta AI voice chat
WABetaInfo claimed that Meta-owned instant messaging platform is developing “Username keys” to make it simple to manage whether a stranger can text them or not.
In addition, WhatsApp will allow users to configure a "Username key," which is a four-digit PIN code. To note, when a user sets up their key, they will have to share both their username and the key to ask someone to send a message for the first time.
This results in those who do not have this key being able to text the user despite having their username. On the other hand, WABetaInfo indicated that real-time voice chat with Meta AI is being expanded to the platform's iOS app.
In the WhatsApp beta for iOS 25.21.10.76 update, the feature tracker spotted the option to initiate two-way voice conversations with the artificial intelligence (AI) chatbot.
It is worth noting that WhatsApp has yet to make an official announcement regarding the launch of the "Username key" feature to its users.
