# Email passwordless Login with Embedded Wallets

Embedded Wallets provides built-in support for email and SMS-based authentication, allowing users to log in seamlessly using a one-time passcode (OTP) sent to their email address or phone number. This form of passwordless authentication simplifies the onboarding process, removes friction for end users, and expands accessibility—especially in regions where social login options may be limited.

## Set up a custom email connection[​](#set-up-a-custom-email-connection "Direct link to Set up a custom email connection")

Enable on dashboard

To use this feature, developers must first enable **Email Passwordless** from the Social Connections section in the [dashboard](https://developer.metamask.io).

By default, Web3Auth uses its own pre-configured credentials for email login.

1. Visit the [dashboard](https://developer.metamask.io).
2. Navigate to the **Social Connections** section.
3. Click the **Settings** icon (next to the toggle for **Email Passwordless**.
4. Enter your custom `Auth Connection ID`.
