For over a decade and a half, one thing was true about WhatsApp: your phone number was your identity. Whether you wanted to join a group chat, message someone new, buy something, or network, you almost always had to give out your mobile number. That’s convenient until it isn’t, especially when it comes to privacy.That’s about to change.Per AP News, WhatsApp just announced one of its biggest updates ever: usernames. Soon, you’ll be able to chat on WhatsApp by sharing a username instead of your phone number. This puts WhatsApp in line with apps like Telegram, Discord, and Signal, where usernames already let people connect without giving out personal numbers. The first step is letting people reserve usernames, and the broader launch is coming later this year.With over three billion users, this is a massive shift, and it’s likely to change how people connect on WhatsApp.What’s changing?Instead of handing out your phone number, you’ll pick a unique username to share when chatting with new people. You’ll still need a number to sign up and verify your account, but now you won’t have to give that out to every new contact. WhatsApp’s letting people claim usernames now, and you might even be able to grab the same handle you’ve got on Facebook or Instagram, if it’s free. Usernames will run between three and 35 characters, giving you plenty of choice.Why is it happening now?The one-word answer for it: privacy. For years, people pointed out that anyone with your number could reach you on WhatsApp. That’s fine for friends and family, but not so great when dealing with strangers, Facebook Marketplace buyers, group chats, or work contacts. WhatsApp says this feature is a direct answer to users asking for more control over their personal info. They want people to be able to talk without putting their mobile number out there for anyone to see. More messaging apps are offering usernames as a privacy safeguard. Signal added it in 2024, and now WhatsApp is doing the same.How does it actually work?WhatsApp is rolling this out carefully. Unlike some apps, there won’t be a public list of usernames you can search. To start a chat, you’ll need to know someone’s exact username. This is deliberate, as it protects people from spam and keeps random users from bothering you. There’s also a new optional security feature called a “username key” that adds even more protection if you want it. And to stop impersonators, WhatsApp’s already blocked off big-name usernames — think politicians, celebrities, and major brands.What does it mean for you as a regular user?If you mostly message friends and family, things won’t feel much different. Your phone number still matters for your account, and your existing chats will work as before. But if you use WhatsApp for business, side gigs, dating, buying or selling things, or joining new groups, this is a relief. No need to hand out your number; just share your username. That’s a big win for anyone who wants to keep their phone number private, especially women, freelancers, public-facing workers, small business owners, or anyone tired of random messages from strangers. The extra control should also mean less spam.A turning point for WhatsApp: Is it the final step of Instagrammification?Usernames are the biggest change to WhatsApp’s identity system since it launched in 2009. Until now, WhatsApp stood out by only using phone numbers. But with privacy concerns rising, WhatsApp is (finally) joining the others in letting users choose what info to share.You’ll still need a phone number to sign up, but for the first time, you can talk to new people on WhatsApp without exposing your digits. For billions of people, that’s a pretty big shift — one that could change how we think about privacy online.And for those who are chronically online on Meta’s other social media platform, this brand new WhatsApp update might just give you déjà vu: you can put up a story, add music to it, mention friends on it, and now, you can set your username as well.Is the ‘Instagrammification’ of a messaging app complete yet?
