## Usage

Returns an active Quick Auth session token when present.

It’s generally preferable to use [getToken](https://docs.neynar.com/miniapps/sdk/quick-auth/get-token) since this will always return a fresh token, however, this property is provided for situations where a synchronous API is useful.

```
import { sdk } from '@farcaster/miniapp-sdk'

// will be undefined
console.log(sdk.quickAuth.token)

await sdk.quickAuth.getToken();

// will return the active token acquired above
console.log(sdk.quickAuth.token)
```

You must [validate the token on your server](https://docs.neynar.com/miniapps/sdk/quick-auth#validate-a-session-token).
