Embedded Signup

What does Embedded Signup mean in practice?

Embedded signup moves a third-party authorisation flow inside the software the customer is already using. For WhatsApp, the business signs into Meta, selects or creates its business assets, chooses a number and grants the platform defined access. The client does not hand an agency its personal password. A safe agency process records which entity owns the account, what permissions were granted, who can revoke them and how offboarding works. Embedded signup reduces setup friction but does not transfer ownership of the client's business asset to the agency.
