WhatsApp is rolling out a major update that will let users chat without sharing their phone number, instead using a personalised username. The change is being rolled out gradually to the platform's 3.3 billion monthly users throughout the rest of 2026.
How the new username system works
The update means users will be able to share a username instead of their actual phone number when messaging new people, casual contacts, or businesses. The phone number will still be linked to the account, but the aim is to keep it hidden from those who do not need it.
Users are not required to switch, but those who delay may find their preferred username taken by someone else. For everyday chats with friends and family, the change may not feel significant. However, for those who use WhatsApp to buy and sell online, arrange pickups, or message people for the first time, a username could prevent their number from being passed around or saved by strangers.
Benefits for businesses and consistency across Meta apps
WhatsApp has said the move will be useful for small businesses and organisations wanting to maintain a consistent online presence. Users will be able to claim the same username they already use across other Meta apps, such as Instagram or Facebook, helping people and brands keep things consistent.
Privacy warning from Which?
Consumer watchdog Which? has flagged the change, writing on Instagram: "WhatsApp is changing in a big way. You’ll soon be able to chat without sharing your phone number thanks to new usernames designed to boost privacy."
Which? tech editor Lisa Barber urged users not to get complacent, saying: "This is one of WhatsApp's biggest privacy changes in years and brings it closer to other messaging apps that let people connect without exchanging phone numbers. For many people, that's a welcome improvement, but remember that a username shouldn't be treated as proof that someone is who they claim to be."
Barber added: "While we're talking WhatsApp security, consider adding two-step verification to your account – it means you'll regularly be asked to enter a PIN to continue using the app. If your phone gets stolen and ends up in the wrong hands, that means your messages will remain locked."
How to enable two-step verification
To switch on two-step verification, open WhatsApp and tap Settings (or the three dots in the top right corner). Select Account, then tap Two-step verification. Tap Enable (or Turn On). Create a 6-digit PIN that you will easily remember. Add your email address so you can safely recover your account if you ever forget your PIN.
