WhatsApp is enhancing account security by replacing its six-digit two-step verification PIN with a more secure password system. Users can now set an alphanumeric or special-character password, which adds an extra layer of protection against account takeovers. The company announced these changes in a recent blog post, highlighting three new security features.

Key Highlights

• WhatsApp replaces six-digit PIN with alphanumeric password for two-step verification.
• New password requires at least eight characters including one letter and one number.
• Passkey support expands with over 1 billion users now using passkeys for account security.
• Android users will see more information about unknown callers including group and country details.

Key Security Updates

The most significant change is the new password system. Previously, WhatsApp relied on a six-digit PIN for two-step verification. The new system allows users to create a longer password, supporting both letters and numbers. This change aims to make accounts harder to compromise through guessing or brute-force attacks.

Users can access the new password option by navigating to Settings and then to Account. If the feature is available, users can set up the new password in the two-step verification section. The password must be at least eight characters long and include at least one letter and one number, offering more flexibility and security than the old PIN.

The new password does not replace the SMS verification code. Users will still need to verify their phone number with a one-time code sent by WhatsApp. The password serves as an additional security measure, not a replacement for SMS verification.

WhatsApp is rolling out the password feature gradually on both Android and iOS. Some users may not see the option immediately and will need to wait for the update to reach their accounts.

Additional Security Enhancements

Alongside the password update, WhatsApp is expanding support for passkeys. The company reports that over 1 billion people now use passkeys to secure their accounts. Passkeys provide another method for users to protect their information and prevent unauthorized access.

WhatsApp is also improving call security on Android. The app will now display more information about unknown callers. This includes details such as whether the caller is from another country or if they share a group with the user. These changes aim to help users identify potential spam or suspicious calls more easily.

Implementation and Availability

The rollout of these new security features is ongoing. Users are encouraged to check their app settings regularly to see if the new password option is available. WhatsApp continues to emphasize account safety and is introducing these updates to reduce the risk of unauthorized access.

These changes reflect WhatsApp's ongoing efforts to strengthen user security and privacy. By offering more robust verification options and additional caller information, the app aims to provide a safer messaging experience for its global user base.
