Passkeys are how you sign in to WatchThis without passwords. You can keep multiple passkeys (for example, one on your phone and one on your laptop) and manage them from your Profile.

1. Go to Profile (/profile).
2. Open the Security tab.
3. Under Passkey Devices, review your active devices.

1. On a signed-in device, go to Profile → Security.
2. Click Add Passkey.
3. Use the claim link or QR code on your new device.
4. Complete the passkey prompt on the new device.

After it succeeds, the new device appears in your device list.

Important:

• You must always keep at least one passkey on your account.
• There’s a limit to how many devices you can have active at once.
