Keeping WhatsApp secure now involves more than avoiding suspicious links. Account takeover scams can start with a stolen verification code, an unexpected call or a linked device that you no longer recognise. This practical guide explains which protections to review, what WhatsApp announced in 2026 and how to respond if something goes wrong.
Quick answer: Review WhatsApp’s account verification settings, set up a passkey if available, check linked devices, keep your phone locked and updated, and never share a registration code or security password with anyone. If a feature has not appeared on your device, update WhatsApp and follow the security options actually shown in your app.
What’s new in WhatsApp security in 2026?
In an August 2026 announcement, Meta described three account-security changes: a stronger form of two-step verification using a password instead of only a six-digit PIN, additional context for unknown callers on Android, and support for adding more than one passkey across devices. Availability and interface details can vary by app version and rollout.
1. Review two-step verification
Open WhatsApp settings, find the account-security options and review two-step verification. Meta says the newer protection can use a longer password with letters, numbers and special characters. Use a unique secret that you do not share or reuse elsewhere. If your version still shows the older PIN flow, follow its prompts and check again after updating.
2. Set up a WhatsApp passkey where available
Meta directs users to Settings > Account > Passkeys. Passkeys allow verification through your device’s biometric or screen-lock method. Meta also says accounts can now support more than one passkey, which can help people using both Android and iOS. A passkey is not a reason to disable your phone’s screen lock.
3. Treat registration codes as confidential
If someone asks for a WhatsApp verification code sent to your phone, do not provide it. Scammers may impersonate a friend, an employer or customer support. A code you did not request is a reason to check your account—not a reason to forward the message.
4. Check linked devices
Open WhatsApp’s Linked Devices section and inspect the sessions. Log out of any browser or computer you do not recognise or no longer use. This is especially important after using a shared or borrowed computer. The exact menu placement may vary across devices.
5. Review unknown callers before answering
Meta’s 2026 update says Android users can see additional context about some unknown callers, including whether the number is from another country and whether any groups are shared. Treat this as context rather than proof of identity. A caller who claims to be from a bank, delivery company or official agency can still be an impostor.
6. Protect the phone itself
Use a strong screen lock, install operating-system and WhatsApp updates from official app stores, and avoid unofficial modified WhatsApp apps. A secure account is harder to protect if someone can unlock the phone and read messages or change settings.
7. Be careful with QR codes and unexpected links
Before scanning a QR code to link WhatsApp to a computer, check that you initiated the action and trust the device. Do not scan a code just because a stranger says it is needed to receive a payment, join a group or verify an account. Similarly, check links independently instead of entering passwords or codes on a page sent by an unknown contact.
8. Reduce information visible to strangers
Review WhatsApp’s privacy settings for profile photo, last seen, online status, group invitations and calls. Choose the visibility that fits your needs. Privacy controls reduce unwanted exposure but do not guarantee protection from fraud.
9. What to do if your WhatsApp account is compromised
- Try to regain access using the official WhatsApp app and its account-registration process.
- Follow the app’s official recovery instructions if additional verification prevents immediate access.
- After regaining control, inspect linked devices and remove unfamiliar sessions.
- Tell close contacts through another trusted channel if scammers may have messaged them.
- Review phone security and email accounts connected to your device.
Do not pay an unknown person who promises to recover your account. Use WhatsApp’s official Help Center for the current recovery instructions.
If your email was compromised too, follow the Gmail account recovery and security checklist to review sessions and recovery settings. For phones running short of space, our Android storage cleanup guide explains how to handle messaging media without casually deleting important backups.
10. A two-minute WhatsApp security checklist
- Check the app is updated from an official store.
- Review two-step verification and choose a strong unique credential.
- Set up a passkey if your app offers it.
- Remove unfamiliar linked devices.
- Confirm your phone has a screen lock.
- Review privacy settings and unknown-caller information.
- Never share registration codes or scan unsolicited login QR codes.
Frequently asked questions
Is WhatsApp end-to-end encrypted?
Meta says WhatsApp uses end-to-end encryption by default for personal conversations. Encryption protects message contents in transit but cannot prevent someone from being tricked into sharing an account code or voluntarily sending money to a scammer.
Does a WhatsApp passkey replace every other security check?
No. It is one sign-in protection. Keep your device secured, review account settings and use the recovery process presented by WhatsApp when necessary.
Can someone steal WhatsApp with just my phone number?
Knowing your phone number alone is not equivalent to controlling your account. Account takeovers commonly involve social engineering, access to verification methods or compromised devices. Treat unexpected verification prompts as a warning.
Do the 2026 features appear on every phone?
Not necessarily. Rollouts and menus may differ by operating system, app version and account. The official announcement explains the features, while your installed app shows what is currently available to you.
