PayPal introduces Passkey as a login option for Android users in the US

Users who utilise the new authentication system may access websites and services that support it without having to enter usernames and passwords. While it can employ biometric authentication to validate a user’s identity, it is not the same as current login technology that auto-fills login fields with facial or fingerprint recognition. The method generates a cryptographic key pair, one public and one private, which is linked to a user’s account. Apps and services that support passkeys use the public key to validate a user’s identity by comparing it to the private key stored on the user’s device.
