WhatsApp is expanding its contact management features, allowing users to upload contacts directly to the app and eventually add new contacts using a username. This feature will initially be available on WhatsApp's web and Windows applications, with plans to expand to other linked devices later. The update aims to provide more flexibility for users who share phones or manage personal and business accounts separately.

The addition of username support is a longer-term goal, which will enable users to create conversations without sharing their phone numbers. This move follows Signal's similar feature and could boost privacy for WhatsApp users.
