# Attach QR-Signer
Adding external QR signers, such as Polkadot Vault (Parity Signer), is a lifesaver and a crucial feature, as it allows you to sign transactions from your mobile wallet.
You’ll first encounter this option on the onboarding page after installing the extension — simply click the **Already have accounts** button and then click the **Attach QR-Signer** button, as shown below.

If you already have accounts in the extension and want to restore additional accounts from a file, simply open the **Account Menu** in the top corner and select **Import Account** (this will redirect you to the **Already have accounts** page).

Alternatively, you can go to **Settings**, open **Account Settings**, and then click **Import Account**.

When you click **Attach QR-Signer**, you’ll see a page where you should position the QR code in front of your camera. The extension will automatically scan the code and proceed to the next page.
On this page you should choose a name for account then, click **Add account** to add the account to the extension.
