Specification

https://w3c.github.io/webauthn/#sctn-getClientCapabilities

Summary

getClientCapabilities() method allows to determine which WebAuthn features are supported by the user's client. The method returns a list of supported capabilities, allowing developers to tailor authentication experiences and workflows based on the client's specific functionality.



Blink component

Blink>WebAuthentication

Motivation

Different clients and authenticators offer varying levels of support for WebAuthn features. This disparity can lead to a fragmented user experience, where some users might encounter errors or be unable to utilize certain authentication options. Providing a way for developers to determine client capabilities enables them to create more robust authentication flows that adapt to these variations.
