+### Passwordless Login
+Passwordless is a two-step authentication flow that requires the **Passwordless OTP** grant to be enabled for your Auth0 application. Check [our documentation](https://auth0.com/docs/get-started/applications/application-grant-types) for more information.
+
+#### 1. Start the passwordless flow
+
+Request a code to be sent to the user's email or phone number. For email scenarios, a link can be sent in place of the code.
+
+```dart
+await auth0.api.startPasswordlessWithEmail(
+    email: "[email protected]", passwordlessType: PasswordlessType.code);
+```
+<details>
+<summary>Using PhoneNumber</summary>
+```dart
+await auth0.api.startPasswordlessWithPhoneNumber(
+    phoneNumber: "123456789", passwordlessType: PasswordlessType.code);
+```
+</details>
+#### 2. Login with the received code
+
+To complete the authentication, you must send back that code the user received along with the email or phone number used to start the flow.
+
+```dart
+final credentials = await auth0.api.loginWithEmailCode(
+          email: "[email protected]", verificationCode: "000000");
+```
+<details>
+<summary>Using SMS</summary>
+```dart
+final credentials = await auth0.api.loginWithSmsCode(
+    phoneNumber: "123456789", verificationCode: "000000");
+```
+</details>
+
+> [!NOTE]
+> Sending additional parameter is supported only on ios at the moment.
