WatchThis uses passkeys, so you don’t need to create or remember a password. A passkey is stored by your device (and can sync across your devices using iCloud Keychain, Google Password Manager, Windows Hello, etc.).

• Use a modern browser that supports passkeys (Chrome, Safari, Edge, Firefox).
• Make sure your device has a screen lock enabled (PIN/biometrics), since passkeys require it.

1. Go to the sign-in page (/auth).
2. Click Create Account.
3. Enter a Username.
4. Click Create Account with Passkey.
5. When your device prompts you, approve the passkey creation (Face ID/Touch ID/Windows Hello/Android lock screen).

• You’ll be signed in automatically.
• Your passkey is saved on the device you used.
• If your password manager or OS sync is enabled, the same passkey may become available on your other devices as well.

If WatchThis says passkeys aren’t supported, switch to a newer browser or update your current one.

Try these in order:

1. Reload the page and try again.
2. Confirm your device has a screen lock set up.
3. Disable strict privacy modes (some private/incognito windows can interfere).
4. If you’re trying to create the passkey inside an embedded browser, open the link in your main browser app.
