WhatsApp is introducing usernames so people can chat without sharing a phone number, though the number still stays tied to the account.
Advanced Chat Privacy and stronger login security are narrowing what others can do with a conversation once it reaches them.
Meta AI inside WhatsApp now includes a private, self-erasing chat mode, alongside built-in image generation.
More than three billion people use WhatsApp, and the app most of them treat as a fixed part of daily life is quietly being rewritten from the inside. The phone number, long the only way to reach anyone on the platform, is being pushed aside as the default identity marker.
At the same time, Meta AI is moving from a simple chat feature into something built around privacy architecture rather than just clever replies. Together, these shifts mark the most substantial change to how WhatsApp works since encryption became standard across every chat.
For close to two decades, a WhatsApp account has meant a phone number, and sharing it was the price of talking to someone new. That is starting to shift. Meta opened username reservations worldwide on June 29, 2026, ahead of the feature's full rollout later this year. A username can run between 3 and 35 characters, and once the feature is fully rolled out, a person's number won't appear to someone messaging them for the first time.
But what matters most is that a phone number is still needed to register and keep an account active. Usernames keep a user's phone number hidden from new contacts, while the number remains tied to the account in the background. WhatsApp also does not provide a public directory for usernames.
Someone needs the exact handle to start a chat, which keeps the feature closer to a quiet introduction tool than an open search system like Instagram's. Given the size of the user base, Meta is also reserving names for public figures and organizations early, to cut down on impersonation before general access opens.
Encryption settles who can read a message. WhatsApp's newer privacy tools settle a separate question: what someone can do with that message after they've already read it.
| Older Protection | 2026 Update | What Changed |
|---|---|---|
| End-to-end encryption | Advanced Chat Privacy | Stops chat exports, auto-downloads, and use of messages in AI features |
| Six-digit PIN for two-step verification | Full alphanumeric password | Makes account takeovers harder to attempt |
| Single passkey per account | Multiple passkeys across devices | Let people log in with face, fingerprint, or screen lock on more than one phone |
| Plain caller ID | Context for unknown callers on Android | Shows shared groups and country of origin before a call is answered |
Advanced Chat Privacy, available in one-on-one chats and groups, is aimed at conversations that are sensitive even among people who trust each other, such as a support group or a small community effort. It's worth being clear about its limits too. The setting does not stop screenshots. It closes automated pathways, not manual ones, and that distinction matters for anyone relying on it.
The account security update from August 2026 rounds this out. Meta says over a billion WhatsApp users have already set up a passkey, replacing codes and PINs with something tied directly to a device.

The most notable AI change of the year isn't about doing more. It's about seeing less. In May 2026, Meta introduced Incognito Chat with Meta AI, built on WhatsApp's Private Processing system. It opens a temporary chat with Meta AI that runs in a secure environment the company says it cannot access, and the conversation disappears once the session ends.
Meta has said plainly why this matters: people bring health questions, money worries, and personal decisions to AI now, and most 'private' modes on other chatbots still let the company see what was asked and answered. A related feature, Side Chat, is planned to let someone consult Meta AI quietly inside an existing conversation, without other participants noticing.
Alongside that, everyday AI tools have grown too. Photo touch-ups and drafted reply suggestions arrived inside the chat window in March 2026. By July, Meta added Muse Image, letting people generate and edit pictures straight inside a WhatsApp chat with Meta AI, starting in a limited set of countries.

Not every update in 2026 is about privacy or AI. Some just fix small annoyances that build up over years of chats. Chat transfer between Android and iPhone finally arrived. This ends a long-standing headache for anyone switching phones.
iPhone users can now run two WhatsApp accounts on one device, something Android already allowed. Storage got better too. Users can now delete individual files from a chat without touching the rest of it. It's a small fix, but it solves one of the most common complaints about the app.
WhatsApp's direction in 2026 points toward separation rather than addition. Identity, privacy, and AI are being split into layers someone can manage on their own terms, instead of one bundle tied to a single phone number. The next real test will be how far Meta pushes this once usernames and Incognito Chat reach full scale and whether the same restraint holds as AI features keep expanding.

1. Do I need to share my phone number to use WhatsApp usernames?
No. Once usernames go live fully, your phone number won't show to someone messaging you for the first time. You still need a number to register and keep the account active, but it stays hidden from new contacts.
2. Does Advanced Chat Privacy stop someone from screenshotting my chat?
No. It stops chat exports, auto-downloads, and use of your messages in AI features. It does not stop manual screenshots, so it's not a full guarantee of secrecy.
3. Can Meta read my Incognito Chat conversations with Meta AI?
Meta says it cannot. Incognito Chat runs in a secure environment built on WhatsApp's Private Processing system, and the conversation disappears once the session ends.
4. Can I switch phones without losing my WhatsApp chat history?
Yes. Direct chat transfer between Android and iPhone is now available, so you no longer need workarounds to keep your messages when switching platforms.
5. How do WhatsApp passkeys work, and are they safer than a password?
Passkeys let you log in using your face, fingerprint, or screen lock instead of a code or PIN. You can now set up more than one passkey per account, useful if you use WhatsApp on multiple devices.
