<div><span>Updated: Nov 4, 2025</span></div><div>You can configure Embedded Signup so that only [business tokens](/books/meta-whatsapp/page/access-tokens-guide-developer-documentation) can be used to access assets owned by customers onboarded via the flow. This approach offers enhanced security by reducing risk associated with [system tokens](/books/meta-whatsapp/page/access-tokens-guide-developer-documentation), flexibility in simplifying onboarding for other Meta assets, and scalability to support a larger number of onboardings. By using a granular token, you can also reduce the negative impact in case of a compromised token, making it a more secure and efficient way to manage your business customer assets.</div><div>Note that App-Only Install can't be used to [onboard WhatsApp Business app users](/books/meta-whatsapp/page/onboarding-whatsapp-business-app-users-aka-coexistence-developer-documentation).</div></div>
