WhatsApp made this possible by supporting passkeys, a newer, more secure authentication method than the old password, which can be forgotten or stolen.
Passkeys are a type of passwordless authentication where the cryptographic key is stored on the device, in this case your Android smartphone. Ownership of the Android phone thus becomes the first authentication factor, the other being some type of biometric authentication, in this case either a facial scan, a fingerprint scan or your phone’s PIN.

Passkeys have become increasingly popular lately, with both Apple and Google gradually moving away from traditional passwords and toward them. For example, Apple allows users to sign in to their Apple IDs on the Internet using a passkey instead of a password, and Google uses passkeys to sign in to Google accounts.
WhatsApp currently only allows passkey authentication on Android devices; There is no information about when this feature will be available on Apple’s iPhones.
