WhatsApp is introducing a username PIN to enhance privacy, requiring new contacts to know both the username and a 4-digit PIN to initiate a conversation.
The username feature is aimed at reducing spam by limiting the ability of unknown users to message you unless they have both your username and PIN.
Though the username support is still in beta and lacks a confirmed release date, it indicates WhatsApp’s ongoing commitment to improving user privacy and security.
Current contacts will not be affected by the new username and PIN security measures, allowing seamless conversations to continue without interruption.
