WebAuthn (Web Authentication API) is a modern authentication standard that enables passwordless and phishing-resistant sign-in using public-key cryptography. It is the underlying technology behind Passkeys, hardware security keys (such as YubiKey), and biometric login methods like Face ID, Touch ID, or Windows Hello.
At this time, WebCatalog does not support WebAuthn, including Passkeys. This is due to a limitation in Electron, the framework WebCatalog is built on, which currently lacks full WebAuthn support. You can track Electron’s progress on this issue here: https://github.com/electron/electron/issues/24573.
