WhatsApp Security Update Adds Alphanumeric Passwords, Multiple Passkeys and More Information About Unknown Callers

WhatsApp has introduced a major security update that allows users to protect their accounts with an alphanumeric password instead of relying solely on a numeric PIN for two-step verification. The new option supports letters, numbers, and special characters, giving users another way to improve their WhatsApp account security.

According to the company, the new feature adds an extra layer of protection against account takeovers. Two-step verification can help keep an account secure even if someone manages to obtain the user's one-time verification code. Users can now create a stronger password that may be more difficult for others to guess.

Alongside the new password option, WhatsApp is also providing more details about calls from people who aren't saved in a user's contacts. On Android, users can see information such as whether the caller's number is registered in another country and whether they have any WhatsApp groups in common.

WhatsApp says this additional information can help people decide whether they should answer an unfamiliar call. Scammers often rely on urgency to push victims into answering calls or making quick decisions, so having more context can give users a moment to assess the situation before responding.

WhatsApp has also revealed that more than one billion users have already enabled passkeys. The feature allows users to verify their identity with a fingerprint, Face ID, or their device's screen lock rather than entering a PIN or verification code. For people who use both Android and iOS devices, WhatsApp now allows multiple passkeys to be added to the same account. This makes it easier to securely access and manage an account across different devices.

These updates follow several other improvements WhatsApp has made to its calling experience. Earlier this year, the app introduced a feature that lets users move an ongoing group call from one device to another without disconnecting.

WhatsApp has also added a waiting room feature, which gives users the ability to approve participants before they can join a call. This provides greater control over who is allowed into a conversation. With these latest security and calling improvements, WhatsApp is giving users more ways to protect their accounts, identify unfamiliar callers, and manage calls across multiple devices.
