# Identify

> Identify users with signal.identify()

# Vue / Browser — Identify

Associate events with a user by calling `signal.identify(distinctId, traits?)` after the user is known (e.g. after login). Use the same API in Vue, Vanilla JS, or any framework.

## identify(distinctId, traits?)

* **distinctId** (`string`) — Unique identifier for the user (e.g. database ID, email).
* **traits** (`Record<string, unknown>` optional) — User properties (e.g. `email`, `name`, `plan`).

Call `identify` after login. Subsequent events will be associated with this user. Call `signal.reset()` on logout to clear identity.

## Vue example

```vue theme={null}
<script setup>
import { onMounted } from 'vue'
import { createSignal } from '@signal-js/browser'

let signal = null

onMounted(async () => {
  signal = createSignal({ endpoint: '...', apiKey: '...', projectId: '...' })
  await signal.start()
})

function identifyUser(userId, properties) {
  signal?.identify(userId, properties)
}

function handleLogout() {
  signal?.reset()
}
</script>

<template>
  <button @click="identifyUser('user_123', { email: 'j@example.com', name: 'Jane' })">Log in</button>
  <button @click="handleLogout">Log out</button>
</template>
```
