We have arrange WebAuthN authentication in a Keycloak occasion, and every thing appears to be working tremendous. My colleagues and I’ve arrange our WebAuthN credentials, and most of us use our cell phones (Android or iOS) as our main credential, however every certainly one of us has a YubiKey as a backup.

In my Chrome browser, I’m given the choice to select from my WebAuthN credentials, and if I select any, there’s a “Strive one other method” button to modify to a distinct credential.
