I see that on some sites (possibly many) the passkeys verification freezes when devtools are opening. I tried to debug and see that it hangs in navigator.credentials.get. STR: Go to https://passkeys-demo.appspot.com/ Enter random username and click Next Enter password and click Next Create a Passkey. Sign out. Select USE ONE BUTTON SIGN-IN INSTEAD Open dev tools. Try to Sign in with passkey. Expected result: User successfully logged in - technically navigator.credentials.get returns credentials. Actual Result: navigator.credentials.get stucks in infinite loading and nothing happened - no any errors. My assertion options looks like: { "challenge": "K8WztCaAZM5-ST7r198F6UD4iLZ09IINHSiDJBgHHq4", "allowCredentials": [], "timeout": 60000, "userVerification": "preferred", "rpId": "passkeys-demo.appspot.com" } In source code on this demo site the code options.allowCredentials = []; <---- breakpoint hit here // Invoke WebAuthn get const cred = await navigator.credentials.get({ publicKey: options, // Request a conditional UI mediation: conditional ? 'conditional' : 'optional' }); const credential = {}; <---- breakpoint NOT hit here (after removing breakpoint above and after macOS touch ID is completed)
