WhatsApp Rolls Out Enhanced Passkeys and Smarter Caller ID

Meta has announced a sweeping series of security updates for WhatsApp. The popular messaging platform is expanding passkey support across multiple operating systems, and giving users more context before they answer calls from unfamiliar phone numbers.

The headline change centers on WhatsApp’s two-step verification mechanism. Previously, protecting an account with an extra secondary check required setting up a numeric six-digit PIN. Under the new security framework, Meta is upgrading this requirement to support full alphanumeric passwords.

Users can now create longer, complex passcodes that incorporate letters, numbers, and special characters. This change makes brute-force guessing far more difficult for hackers who manage to steal or intercept a primary one-time verification SMS code. The added layer helps prevent unauthorized account migration when someone attempts to set up an existing phone number on a new device.

WhatsApp is also introducing an enhanced caller context card on Android devices. Scammers frequently rely on high-pressure tactics, posing as financial institutions, delivery services, or acquaintances to trick targets into sharing sensitive credentials or sending money.

When an incoming call arrives from a phone number not saved in your address book, WhatsApp will now present additional background information on screen. This includes:

• The country where the phone number is registered.
• Any mutual group chats you share with the caller.

By highlighting these key details immediately, the app gives users a brief moment to evaluate the legitimacy of a call before picking up or declining it altogether.

Furthermore, Meta has shared an update on its adoption of passkey technology. To accommodate multi-device workflows, WhatsApp now permits users to attach multiple passkeys to a single account across both Android and iOS devices. If you use an iPad or an Android tablet alongside an iPhone, for instance, you can now enroll passkeys on both platforms seamlessly.
