WhatsApp is preparing one of its most significant privacy changes in years by moving beyond phone numbers as the main way people identify themselves. In a future update, users will be able to share a username instead of their personal number, and the feature is already available for reservation on the latest iPhone and Android app versions.
The change matters because WhatsApp has long been built around the phone number as the core account identity. That made it easy to connect, but it also meant that anyone starting a conversation could immediately see a personal number that many users would rather keep private.
A cleaner way to start conversations
Meta says the update is meant to help in situations where people want to join a group or speak with someone new without exposing a phone number tied to banking, social media, and even government services. With usernames, the account can stay connected to WhatsApp while the regular number stays hidden from other people.
WhatsApp is also designing the feature to keep contact access tight. There is no directory to browse and no account suggestions, so the only way to reach someone for the first time is to know the exact username.
| Feature | What It Does | Privacy Impact |
|---|---|---|
| Username sharing | Lets users share a username instead of a phone number | Hides the personal number from new contacts |
| Exact-username discovery | No browsing directory or account suggestions | Makes unsolicited contact harder |
| Optional username key | Adds an extra step before messages can be sent | Gives users more control over who can reach them |
Extra control through a username key
WhatsApp is adding an optional username key that must be known before another person can send a message. That gives users a second layer of control on top of the username itself, which should be especially useful in marketplaces, large groups, or first-time interactions with strangers.
The approach keeps the service familiar while reducing how often a personal phone number becomes part of everyday conversations. For many users, that is the most noticeable privacy upgrade WhatsApp has made in a long time.
Reservation is open, but usage is not yet live
The username can already be reserved by users who have updated to the latest app version, but it is not yet available for chatting. On Android and iPhone, the reservation path is found under Settings > Account > Username.
WhatsApp is also setting aside certain usernames for major brands and public figures that already have Meta accounts on Facebook or Instagram. The move is meant to help important names claim consistent identities once the feature becomes active.
A broader move away from phone-only identity
The update follows a wider shift inside WhatsApp, which already supports email-based login and can bypass the old phone number and SMS sign-in flow. With usernames added on top, the app is moving closer to a setup where a personal number does not need to be exposed in daily use.
That direction also makes WhatsApp look more aligned with other Meta services. For users, the change may seem small at first glance, but it addresses one of the most sensitive parts of the app and could become one of its most meaningful privacy updates in years.
