> Generate an access token for your users by sending them a magic link to their email

# Magic link

<Steps>
  <Step title="Send an email with magic link">
    Using the WalletKit client, send an email to the user's email address. This will contain a magic link that the user can click to verify their email address.

    ```typescript Typescript theme={null}
    const wk = new WalletKitClient({..});

    const loginWithMagicLinkResp = await wk.users.loginWithMagicLink({
        email: "<user email>",
    })
    if (!loginWithMagicLinkResp.ok) {
        // handle error
    }
    ```
  </Step>

  <Step title="Wait for user to click the link">
    In your app, ask the user to click the link sent to their email. You can wait for the user to click the link by polling the WalletKit API.

    ```typescript Typescript theme={null}
    const sessionChallengeResp = await wk.users.getSessionChallenge({
        code: loginWithMagicLinkResp.body.code,
    });
    if (!sessionChallengeResp.ok) {
        // handle error
    }

    if (sessionChallengeResp.body.expired) {
        // handle expired
    }

    if (sessionChallengeResp.body.completed) {
        // handle completed, see next step on how
    }
    ```
  </Step>

  <Step title="Get access token">
    Once the session challenge has been completed, you can get the access token for the user.

    ```typescript Typescript theme={null}
    const verifyLoginResp = await wk.users.verifyLogin({
        sessionChallengeCode: sessionChallengeResp.body.code,
    });
    if (!verifyLoginResp.ok) {
        // handle error
    }
    ```
  </Step>

  <Step title="Handle access token">
    If you are using one of the WalletKit SDKs, you can skip this step - the SDK will handle this for you.

    If you are using the WalletKit API directly, you will need to store the access token returned by the `verify-login` call. This token is used to authenticate the user in subsequent API calls.

    ```bash curl theme={null}
    curl --request GET \
      --url https://testnet.walletkit.com/wallets \
      --header 'X-WalletKit-Project-ID: <Project ID>' \
      --header 'Authorization: Bearer <Access Token>'
    ```
  </Step>
</Steps>
