Power Apps portals offer several options for controlling account sign-up behavior. We prefer to use external accounts of “trusted” identity providers to let external users register and sign in. Self-service sign-up user flows, part of External Identities in Azure AD, can be customized and extended with API connectors that can call Power Automate flow via Azure API Management. We’re going to set up a self-service sign-up user flow for Power Apps portals, where we can use Power Automate flow to perform identity verification of the external user based on: - The e-mail address of a matching Contact record in Dataverse. These Contact records were added by internal users or by portal contacts from the parent account page. - The e-mail domain of a matching Account record in Dataverse. In this way we can offer an open registration for verified external users and block the registration for John & Jane Doe.
