### 1. Create Identity
Create a Identity for your user and store it in your your databases user collection.
```javascript
const { THXAPIClient } = require('@thxnetwork/sdk');
const thx = new THXAPIClient({
apiKey: '',
});
const identity = await thx.identity.create();
// e7f32a71-33ea-418e-9d80-32b6bf6405f0
```
{% hint style="success" %}
Tip: Store the identity code in the account in your database. You will need this to assign events to the same user.
{% endhint %}
#### Deterministic Identities
If you can't or don't want to store identities in your database, you can use a salt to derive a deterministic identity.
```javascript
const identity = await thx.identity.get("0x742d35Cc6634C0532925a3b844Bc454e4438f44e");
// 225a3287-ca4d-6b9d-30a2-860ab99db2fd
```
### 2. Connect Identity
Choose one the following methods to connect an Identity to a THX account.
#### 2.1. Seamless
Connect the Identity of your user to a THX account programmatically using THXWidget. As soon as the account completes a successful sign in the Identity will be connected.
```javascript
window.THXWidget.setIdentity("a6021617-9aab-4194-b2af-a4dd0cc96f84")
```
#### 2.2. Prepopulate
Connect the Identity of your user to a THX account in the frontend using your campaign widget. Users will be prompted for authentication if they are not signed in yet before they can connect.
```javascript
window.THXWidget.connect("a6021617-9aab-4194-b2af-a4dd0cc96f84")
```
#### 2.3. Manual
Share the Identity with your users and ask them to connect their identity manually using the menu item "Identities" in the navigation dropdown.
