What is a passkey?

Passkeys represent an innovative step forward in passwordless authentication by leveraging biometric technology and cloud-based interoperability, aiming to replace traditional passwords with more secure alternatives. Developed by the Fast Identity Online (FIDO) alliance, passkeys use biometric verifications such as FaceID or TouchID, backed by end-to-end encrypted cryptographic key pairs stored in the cloud, allowing seamless cross-platform and cross-device authentication. Despite their user-friendly design and resistance to phishing, passkeys face challenges related to implementation, including compatibility issues with cloud-syncing functions and inherent biases within biometric systems. Adoption is expected to be gradual as technological integration progresses. Companies like Stytch are actively supporting this transition by incorporating passkeys into their suite of authentication solutions, enhancing both security and user experience in digital interactions.
