# Login with OTP

### Try It Yourself

This demo uses **Fyntel Telecom** as a **simulated service provider portal** to demonstrate how a telecom operator can securely authenticate a resident using their National ID before allocating an eSIM.

Click **here** to navigate to the [**Fyntel eSIM Allocation Portal**](https://esim-mosipid.collab.mosip.net/), and follow the steps below to complete the eSIM allocation flow using **OTP-based authentication via eSignet**.

### Step-by-Step Flow

#### Step 1: Access the eSIM Portal

The resident opens the [**Fyntel Portal**](https://esim-mosipid.collab.mosip.net/) and clicks **Get Started** to begin the authentication process.

#### Step 6: Provide Consent

After successful authentication, the resident is redirected to the **Consent screen**.

* **Essential claims** required for eSIM allocation are mandatory
* **Voluntary claims** are optional and may be selected by the resident
* A **master toggle** allows selecting all voluntary claims at once
* The consent screen is shown only if consent has not been previously granted
* A timer is enforced; if no action is taken within the allowed time, the resident is redirected back to the eSIM portal

The resident reviews the details, verifies their accuracy, and clicks **Submit**.
