# Sign in with a passkey

> Use a saved passkey instead of typing your password.

If you already [added a passkey](/help/account/how-to-add-a-passkey.md), you can sign in with it from the sign-in page. You do not need to enter your email first.

**1. Open the sign-in page**

Go to [Sign in](https://app.vocabmonster.com/login).

**2. Choose Sign in with a passkey**

Select **Sign in with a passkey**. Your browser, device, or password manager prompts you to verify.

**3. Complete the device prompt**

Use a fingerprint, face recognition, device PIN, or security key. When verification succeeds, you return to the app.

> [!NOTE]
>
> Keep another sign-in method available. If the passkey option is missing, or you see that passkeys are not enabled, use password, Google, or a magic link and contact [help@vocabmonster.com](mailto:help@vocabmonster.com) if that should not be the case.
>
> Passkeys require a supported browser and a secure connection (HTTPS).
