Add a passkey once from **Sign In & Security**, then sign in with **Use a passkey** and your device's fingerprint, face or security key.

## Add a passkey

1. Select your avatar, then **Settings**, then **Sign In & Security**.
2. Find the **Passkeys** section. When no passkey exists it reads **Set up a passkey to sign in with biometrics or a security key.**
3. Select **Add passkey**.
4. Follow your browser's prompt. The button reads **Adding passkey...** while it waits.

Each registered passkey is listed with the date it was added, for example **Added 4 September 2026 via platform.** Select **Remove** on a row to delete that passkey.

## Sign in with it

1. Open `/en/signin`.
2. Select **Use a passkey**. The button reads **Waiting for passkey...** while your browser prompts you.
3. Approve the prompt on your device.

You do not need to type your email address first.

## If it did not work

- **Passkeys are unavailable for this account.** means passkeys are not offered for your Account. Use your password.
- **Passkey sign-in is unavailable. Try your password instead.** on the sign-in page means the browser refused or cancelled the prompt. Sign in with your password and try adding the passkey again.
- **Unable to add a passkey.** means registration failed. Check that the browser and device support passkeys, then retry.
- The **Passkeys** section is hidden entirely when your Account does not support passkeys and none are registered.
