## :dart: Why use Sign in with Google and Apple

If you are a Shopify Plus merchant who uses Legacy account mode, this feature eliminates friction from the login experience by allowing users to access your app with a single tap without remembering or typing passwords.

* Existing customers can sign in instantly using their Google/Apple account associated with their current email address.
* New customers can register just as quickly via either a Google or an Apple account. When they later log in to your online store, they can simply use the **Forgot password** option to set one.

This will lead to faster onboarding, increased sign-up completion rates, and fewer abandoned sessions. At the same time, it leverages the security and trust of Apple and Google’s authentication systems, helping to protect user data while providing you with cleaner, more reliable customer accounts from day one.

## 📌 Prerequisite

✅ **Before proceeding, make sure:**

* You are a Shopify Plus merchant
* You use Legacy customer account mode

### 2. Share your Firebase project with SimiCart

### 4. Request to publish

Once you've completed the above steps, navigate to our Publish page and send us a request to publish the app and go live with this feature!

## :warning: Important note

* This feature hasn't been made compatible with [**B2B registration form**](https://docs.simicart.com/~/revisions/lspglNg5BIN60rn3duh6/features/gaining-new-users/b2b-registration-form-or-bss-b2b-and-wholesale-solution-integration) to support the registration process.
* Multipass should not be switched off as the connection would be broken and the feature would not work. Turning the feature back on requires repeating [Step 3](#id-3.-configure-multipass-connection).
