The payments giant today announced that it adding passkeys as a log in method for PayPal accounts, allowing iPhone, iPad and Mac users on PayPal.com to sign in without using a password. Users with devices that don’t support passkeys can still tap an iPhone to log in with a PayPal passkey, but they’ll have to scan a QR code that appears after they enter their username. Passkeys are a relatively new industry standard created by the FIDO Alliance and the World Wide Web Consortium — in partnership with Apple, Google and Microsoft — that are designed to replace passwords with bits of data called cryptographic key pairs. The pairs consist of a public key stored in the cloud and a private key stored locally on users’ devices, separated to ensure that a compromised server won’t give an attacker access to account credentials.
