WhatsApp 2SV Security Upgrade: New Alphanumeric Passwords, Multiple Passkeys for Scam Protections

WhatsApp, the ubiquitous messaging platform owned by Meta, has significantly upgraded its account security features, introducing more robust two-step verification (2SV) options and enhanced passkey management. The update, rolling out today, August 25, 2026, aims to provide users with stronger protection against account takeovers and sophisticated scams.

Previously reliant on a simple six-digit PIN, WhatsApp's two-step verification now allows users to create longer, alphanumeric passwords that can include special characters. This crucial change dramatically increases the complexity and resilience of the security layer, making accounts much harder to compromise. "Until now it was a six-digit PIN, we've now upgraded it to a full password: longer, alphanumeric, and even with special ch@racters to make it harder to guess. If you've been using '123456,' this is your sign to upgrade," WhatsApp stated. What is Android Pulse? Know All About Google’s New Mysterious App Listed on Play Store.

Enhanced Two-Step Verification

The upgraded two-step verification is an optional yet highly recommended feature. It serves as an additional shield, preventing unauthorised access even if an attacker manages to obtain a user's one-time passcode. This marks a substantial improvement from the system first introduced in 2017. WhatsApp has noted that these new 2SV passwords must include at least eight characters, comprising one number and one letter, with special characters being optional.

Multiple Passkeys and Smarter Call Screens

In addition to the 2SV overhaul, WhatsApp is also expanding its passkey support. While passkeys, allowing logins via fingerprint, Face ID, or screen lock, were first introduced for Android in October 2023 and expanded to iOS in early 2024, and are already used by over a billion people, the new update enables users to add more than one passkey to their account. This is particularly beneficial for individuals who use WhatsApp across both Android and iOS devices, streamlining secure logins across platforms. To manage passkeys, users can navigate to Settings > Account > Passkeys.

Furthermore, Android users will now receive more context when receiving calls from numbers not saved in their contacts. The incoming call screen will display additional information, such as the caller's country of origin and any shared WhatsApp groups. This feature is designed to empower users to make more informed decisions about answering calls, thereby adding an extra layer of defence against scam attempts, which often rely on a sense of urgency. WhatsApp Scam Alert Feature: New Beta Feature Rolled Out by Platform To Detect Fraud; Know How It Works.

Broader Security Push

These latest security enhancements are part of a continuous effort by WhatsApp to combat evolving threats and protect its vast user base. Earlier this year, in March, WhatsApp rolled out warnings for fraudulent device-linking requests. A limited beta rollout of an optional "Scam Alert" feature, using local machine learning to flag suspicious messages, was also introduced earlier this month. With over 3 billion people globally relying on its services, WhatsApp continues to prioritise user safety and privacy.
