In the third part of the "The Power of Descope Flows" blog series, the focus is on the adoption of passkeys as a modern alternative to traditional passwords for enhancing both security and user experience in digital authentication. Passkeys, supported by the FIDO Alliance and major tech companies like Apple, Google, and Microsoft, use biometrics and public-private key pairs to authenticate users without sharing secrets between client and server, thereby reducing security risks. Despite their benefits, the complexity of implementing passkey support has limited their widespread adoption, which is where Descope Flows—a no-code workflow editor—comes into play, allowing developers to easily integrate passkeys into their applications. The blog details how passkeys can be incorporated at various points in the user experience, such as at the end of the authentication flow, within user profiles, and on login pages, promoting their use for both new and existing users. It explains the steps necessary to seamlessly integrate passkeys, including the configuration of login pages to support biometric authentication and enabling autofill features, thereby offering a streamlined and secure user login experience.
