Passkeys are emerging as a strong, convenient alternative to traditional passwords, offering a passwordless authentication method that enhances security and user experience. Unlike passwords, which are susceptible to theft and require user management, passkeys use asymmetric cryptography, with private keys stored on users' devices and public keys on servers, making them virtually unphishable. They incorporate multi-factor authentication (MFA) in a single step by using biometrics to unlock the private key on the device, emphasizing privacy as biometric data never leaves the device. Built on widely-supported standards like FIDO2 and WebAuthn, passkeys are gaining cross-industry backing from major tech companies such as Google, Apple, and Microsoft. While still in the early stages, passkeys are poised to replace passwords, reducing the burden on developers and IT teams by preventing server-side authentication complexities. Descope offers developers tools to easily implement passkey authentication into their applications, facilitating a secure and frictionless user experience.
