# SDK Tokens

**Tokens** enable clients to send personal data to ComplyCube via our SDKs. They are [JWTs](https://jwt.io/).

Each token is confined to one client and **expires after 60 minutes**, so you can safely use them at the front end of your application.

The generated token takes the following form: `{"token": "header.payload.signature"}`.

{% hint style="info" %}
You must generate a new token each time you initialize the ComplyCube SDKs.
{% endhint %}
