• WhatsApp has rolled out a new 'Passkeys' feature for iPhone users.
• This update leverages Apple’s biometric technologies to offer a more secure authentication method.

A major move of WhatsApp to integrate more security features and make the login process easier for iOS users has introduced passwordless authentication with a new 'Passkeys' feature. This move is consistent with the Android Passkeys deployment, indicating a more widespread adoption of more secure and convenient authentication methods.

Secure and Simple Authentication

The latest update for iPhone offers an option to log into WhatsApp through the use of Apple's biometric mechanisms (Face ID and Touch ID) as well as the use of the device passcode. This approach replaces the old SMS-centred OTP (one-time password) methods that are vulnerable to interception and a host of other risks.

WhatsApp argues that the implementation of Passkeys makes for a tighter security framework, as OTPs transmitted over SMS are securely transmitted through a local data connection. 

Users may appreciate constant access to their accounts, even in scenarios that have a poor or obstacle-free connection to networks. This attribute is especially valuable in regions where internet services can't be relied on; therefore, messages will be saved and users can proceed with their communications unaffected.

Setting Up Passkeys

To activate the iPhone’s 'Passkeys', follow the Settings - Account - 'Passkeys' menu option of the WhatsApp app. The setup is simple where one can choose his preferred biometric authentication methods of face ID or touch ID for his accounts. 

Right after setup, the whole process of identification becomes very fast as face recognition and fingerprints are backed up locally and not online, thereby giving users the best protection.

Towards a Password-Free Future

Logins without passwords that WhatsApp is striving to achieve is an indication of the evolution in the field of digital security. Various other platforms and services such as Google have started implementing this Passkey technique, which points to that shortly we will be saying goodbye to human passwords and embracing new more secure, and convenient ways of authentication.
