Quick Answer
WhatsApp Scam Alert is an optional beta feature that uses an on-device machine-learning model to flag likely scam messages from people outside your contacts. Meta says message content does not leave your phone for classification, and alerts are not automatically reported. Turn it on only if the beta option appears, then review every warning before blocking, reporting, or trusting a chat.

What is WhatsApp Scam Alert?
WhatsApp Scam Alert is an optional security feature that warns recipients when WhatsApp’s on-device model identifies a message from a non-contact as a likely scam attempt. Meta began a limited beta rollout on August 12, 2026, which means many WhatsApp users will not see the feature yet.
WhatsApp Scam Alert places the warning directly inside the chat rather than sending a separate notification that could be missed or mistaken for another message. The alert is visible only to the recipient, according to WhatsApp, so the sender does not know that the conversation was flagged. That design gives the recipient time to assess the message without signaling their decision to a suspicious account.
WhatsApp Scam Alert is not a replacement for careful judgment. A scam warning indicates that the model found patterns associated with likely scam activity, but an alert can be wrong. The most sensible response is to pause before replying, avoid sharing sensitive information, and use the available blocking or reporting options if the conversation appears unsafe.
WhatsApp’s expanding privacy features also make account identifiers more important. Users considering WhatsApp username privacy should still treat unexpected requests from unfamiliar accounts with caution, even when a message does not trigger a warning.
How does WhatsApp Scam Alert protect message privacy?
WhatsApp Scam Alert is designed to classify messages on the device, which means WhatsApp says message content does not leave the phone for scam detection. Meta described the system as an on-device machine-learning model that works alongside WhatsApp’s end-to-end encryption rather than requiring message content to be sent to Meta, WhatsApp, or another party for review.
WhatsApp’s privacy approach matters because scam detection often creates a difficult tradeoff. A cloud-based system can inspect content remotely, while an on-device system evaluates the message locally. WhatsApp says its model makes the classification on the recipient’s device and does not automatically report a flagged message to the company.
WhatsApp’s broader security model is outlined on its official security page. Its privacy policy also explains how WhatsApp handles information across its services. The practical limitation is that on-device classification does not make every chat safe, and it does not remove the need to verify unexpected requests independently.
WhatsApp Scam Alert also gives users control over what happens after an alert appears. The feature can help surface suspicious behavior, but the recipient decides whether to block the sender, report the account, continue the conversation, or mark the chat as trusted.
What happens when WhatsApp Scam Alert flags a message?
WhatsApp Scam Alert displays a warning in the chat when the on-device model decides that a message is likely to be a scam. WhatsApp says only the recipient sees the alert, which prevents the sender from learning that the message has received extra scrutiny.
WhatsApp provides 4 possible responses after an alert appears. Recipients can block the sender, report the sender, continue the conversation, or mark the chat as trusted. Marking a chat as trusted prevents future false flags from that contact, which can be useful when a legitimate new contact was incorrectly identified as suspicious.
| WhatsApp Scam Alert option | What it does | When it makes sense |
|---|---|---|
| Block | Stops the sender from contacting you through WhatsApp. | Use it when the message is unsolicited, coercive, or clearly suspicious. |
| Report | Sends the account for WhatsApp review when the recipient chooses to report it. | Use it when the message appears to be a scam attempt. |
| Continue conversation | Leaves the chat available without treating the alert as a final decision. | Use it only after independently confirming who is contacting you. |
| Mark as trusted | Prevents future scam flags from that contact. | Use it when a legitimate contact was flagged in error. |
WhatsApp Scam Alert warnings deserve attention because a trusted designation changes how future messages from that account are handled. Do not mark an unfamiliar chat as trusted merely because the sender uses a recognizable name, claims urgency, or asks you to move the conversation elsewhere.
How do you turn on WhatsApp Scam Alert?
WhatsApp Scam Alert can be turned on only when the limited beta feature is available in your version of WhatsApp. Meta describes Scam Alert as optional, but the available research does not provide a confirmed settings path or a universal release date for all US users.
Check the privacy and security areas of WhatsApp settings if your account has access to the beta. Review the feature description before enabling it, because the important distinction is that Scam Alert provides warnings about likely scams rather than automatically blocking or reporting conversations on your behalf.
- Open WhatsApp and check whether your account has access to the Scam Alert beta option.
- Review the feature description to confirm that the alert is optional and on-device.
- Enable WhatsApp Scam Alert if the option is available and you want warnings for likely scam messages from non-contacts.
- Read any future chat warning before choosing to block, report, continue, or trust the sender.
WhatsApp Scam Alert availability remains the main limitation for now because the rollout is still a limited beta. Stop after checking your app settings if the option does not appear, rather than installing unofficial WhatsApp builds or APK files that claim to unlock the feature. Unofficial software can create a separate account-security risk.
Can WhatsApp Scam Alert make mistakes?
WhatsApp Scam Alert can produce false flags because the feature uses a machine-learning model to identify likely scam messages rather than proving that a sender is fraudulent. WhatsApp explicitly allows recipients to continue a conversation or mark a chat as trusted, which recognizes that an alert is not a final verdict.
WhatsApp Scam Alert may be most useful when an unfamiliar account sends an unexpected message and asks for personal details, money, account access, or an urgent response. The warning adds a reason to slow down, but the recipient still needs to verify the sender through a separate, known contact method before sharing any sensitive information.
WhatsApp Scam Alert also cannot identify every harmful message. A conversation can remain risky even if no warning appears, especially when the sender impersonates a friend, business, government agency, or support worker. Similar pressure tactics appear in QR-code phishing scams, where the request itself should be checked before the recipient follows instructions.
The practical response is to treat WhatsApp Scam Alert as one signal among several. Check the sender’s identity, avoid opening unknown links, and do not provide passwords, verification codes, financial details, or recovery phrases in response to an unsolicited chat.
What is Meta doing to test WhatsApp Scam Alert?
Meta is testing WhatsApp Scam Alert through an expanded Bug Bounty program before a broader release. Meta says security researchers received an early-access APK build so they could confirm that message content does not leave the device and that flagged messages are not automatically reported.
Meta also provided experienced AI and machine-learning researchers with the model weights, according to the rollout information. The stated purpose is to allow researchers to evaluate whether the model is purpose-built for scam detection rather than another undisclosed use.
Meta’s Bug Bounty program provides a channel for security researchers to report product issues. Independent testing is important because privacy claims about on-device AI depend on both the model’s behavior and the way the app implements the feature in real releases.
WhatsApp Scam Alert remains in beta, so testing does not guarantee that the system will identify every scam or avoid every false positive. The most useful interpretation is narrower: Meta is giving researchers an opportunity to examine the privacy and reporting boundaries before the feature reaches a wider audience.
Should you rely on WhatsApp Scam Alert alone?
WhatsApp Scam Alert should not be the only protection you use against suspicious messages. The feature can identify likely scams from non-contacts, but it cannot replace the basic checks that prevent a rushed response from becoming an account, identity, or financial problem.
WhatsApp Scam Alert is most helpful as an interruption. A visible warning can create time to inspect a request that might otherwise look routine, particularly when a sender pushes for immediate action. That said, a familiar-looking name and a polished message are not proof that a conversation is legitimate.
- Verify unexpected requests through a phone number, website, or contact method you already know.
- Keep passwords, verification codes, banking details, and recovery phrases out of unexpected chats.
- Block and report accounts that appear to be impersonating a person or organization.
- Use caution with messages that claim to be technical support, especially when they request remote access or account credentials.
WhatsApp Scam Alert can complement other account-safety habits, including caution around fake IT helpdesk calls that try to move a target from one communication channel to another. Stop and contact the real organization through its official contact details if a message involves account access, payment, or an urgent security claim.
