[Open the **Windows Settings** app](https://support.microsoft.com/en-us/windows/find-settings-in-windows-6ffbef87-e633-45ac-a1e8-b7a834578ac6) by clicking the **Start** button in the bottom-left corner and then click the gear icon or search for "Settings" in the search field. If you cannot find the **Settings** app, [check this page for assistance locating it](https://support.microsoft.com/en-us/windows/find-settings-in-windows-6ffbef87-e633-45ac-a1e8-b7a834578ac6). 3. In the left menu, click **Accounts**. 4. Under the **Account settings** section, click **Sign-in options**. 5.
