WhatsApp’s long-awaited username feature is now officially rolling out to users. But almost as soon as it was announced, many began asking an obvious question: won’t this make it easier for scammers to message strangers? Now, WhatsApp has stepped in to explain why it believes that won’t happen.
WhatsApp says usernames aren’t as open as Telegram’s
Much of the concern stems from comparisons with Telegram, where anyone can search for a public username and immediately start a conversation. Several users on X argued that hiding phone numbers improves privacy but also removes a layer of accountability that helped identify suspicious contacts.
As the rollout began, WhatsApp responded directly to users on X, explaining that its implementation works very differently. For starters, there won’t be a public directory or username suggestions to help people discover accounts. Instead, someone will need to know your exact username before they can even try to contact you.
The company also revealed another privacy layer called a username key. If users choose to enable it, nobody can message them using their username unless they also know that key, adding an extra hurdle for unwanted messages. WhatsApp says it has built several anti-abuse measures into usernames from day one. The company will rate-limit how many new people an account can contact, block repeated attempts to guess someone’s username key, and use existing systems to detect and remove impersonation or other suspicious activity.
Furthermore, even if someone does message you, WhatsApp says the app will continue to provide useful context, including whether the sender is a new account, already in your contacts, shares a mutual group with you, or is based in another country. Users will still have the same options to block, report, or ignore unwanted conversations.
Privacy comes with new responsibilities
The funny thing is that WhatsApp’s biggest challenge isn’t the technology; it’s changing user habits. On most social platforms, people try to grab a username that matches their real name. While WhatsApp emphasizes there won’t be a public directory to browse, using your real name could still make your handle easier to guess. If privacy is the ultimate goal, choosing a more unique username may be the smarter move.
As usernames gradually roll out to more users, it’ll become clearer how well these protections hold up in the real world. But one thing is already clear: WhatsApp knew the scam concerns were coming, and it has designed usernames to prioritize privacy over discoverability, making them far less open than many users initially feared.
