Troubleshooting: Passkey Prompts Not Showing

Fix missing passkey prompts by checking browser support, device settings, and sign-in flow.

Last updated February 4, 2026

If you click Sign In with Passkey (or Create Account with Passkey) and no system prompt appears, try the steps below in order.

1) Confirm Your Browser Supports Passkeys

Passkeys require a modern browser. If WatchThis shows “Passkeys Not Supported,” update your browser or switch to Chrome, Safari, Edge, or Firefox.

2) Make Sure You’re in a Secure Context

Passkeys require HTTPS (the common exception is http://localhost in development). If you’re on an insecure connection, the prompt may not appear.

3) Check Device Settings (Most Common Fix)

Passkeys require a working platform authenticator. Make sure:

You have a screen lock enabled (PIN/biometrics).
Face ID / Touch ID / Windows Hello / Android screen lock is set up.
Passkeys aren’t disabled by device policy (common on managed/enterprise devices).

On a brand new device, you might not have a WatchThis passkey available yet.

If your passkeys sync, sign-in should work normally.
If they don’t sync, add a passkey on that device from an existing signed-in session.

5) Try a Normal Browser Tab (Not Embedded)

If you opened WatchThis inside an in-app browser or embedded web view, passkey prompts may be blocked. Open the site directly in your main browser.

6) If It Works on /auth but Not on a Claim Link

Some browsers require a user click before showing passkey UI. If you’re adding a new passkey device via a claim link and it seems like “nothing happens,” reload the page and try again, or complete the flow in a browser/device that reliably supports passkey registration.
