WhatsApp adds new security features to prevent fraud

Meta has announced the addition of new security features to WhatsApp, aimed at protecting users' accounts from hijacking and risks associated with suspicious calls and scams. The updates include developing a two-step verification mechanism that uses a strong password instead of a 6-digit code, which enhances the difficulty of account hacking—especially in cases of stolen temporary verification codes. WhatsApp has also added contextual information when receiving calls from unknown numbers, such as the country associated with the number and whether the caller is part of shared groups, to help identify suspicious calls. Data indicates that over a billion users utilize password keys to enhance login security, relying on encrypted data stored on users' devices, making hacking or phishing attempts more difficult. Additionally, WhatsApp has introduced a backup security feature that uses password keys, and now supports linking multiple password keys across different devices to strengthen protection against phishing attacks and data theft. These measures aim to reduce the likelihood of account hijacking and improve detection of suspicious calls, as part of ongoing efforts to enhance user security and protect their privacy.
