WhatsApp rolls out usernames: here’s everything you need to know

CALIFORNIA: WhatsApp, the Meta-owned messaging behemoth used by billions across the planet, is finally killing off its most awkward legacy quirk: the assumption that your phone number is also your identity. A gradual global rollout now lets users adopt a username, prefixed with the familiar @ symbol, so strangers, salesmen and the occasional scammer no longer need your digits to find you.

The mechanics are simple enough. Pick a handle, say @Name123, and it becomes the public face of your account for anyone who has not already saved your number. Your display name stays separate and need not be unique; the username must be. Contacts who already have you saved notice nothing different. Everyone else sees only the handle.

There is no searchable directory, so a username must be typed in full and exact to start a chat, more akin to an email address than a social-media tag. Businesses, governments and assorted public figures get first dibs on the juiciest handles, which ordinary mortals cannot prise away.

For the security-conscious, WhatsApp throws in a username key, a company-generated code that acts as a second lock. Without it, newcomers cannot message you on the strength of your handle alone, though anyone already in your contacts, group chats or who has scanned your QR code sails through unimpeded. Under-18s linked to other Meta accounts get the key switched on automatically, a rare nod to caution from a firm not always famed for it.

Where the feature has yet to land, users can reserve a handle in advance, locking it away from rivals until it goes live. The catch: reservations and keys both require a mobile handset, with desktop and web users locked out for now.

Delete or swap a username and your number reappears for old chats, and the handle itself goes back into the pool for the next chancer to grab. In an app built on phone numbers since 2009, that is no small rewrite. Bin the digits, keep the chat: WhatsApp’s billions are about to get a little more anonymous, and a lot harder to cold-call.
