WhatsApp is rolling out usernames, letting users chat without sharing their phone number. Instead of giving someone your phone number, you can share a unique username. This makes it easier to keep your phone number private when talking to new people. The feature is rolling out in stages, so not everyone will get it at the same time. - You can create a unique username for your account. - People will need your exact username to message you. - There will be no public list of usernames to search. - Your phone number will still be used to create, verify, and recover your account. - Some usernames have been reserved to prevent impersonation of well-known people and brands.
