Power Pages (formerly Power Apps portals) lets you build secure, external-facing websites that read and write data directly to Dataverse, for example a citizen self-service portal, a supplier onboarding site, or a customer account area, without exposing your internal systems directly.
Citizen or member self-service portals for local government and membership bodies, supplier and partner portals, and customer account areas that let external users check status or submit requests without a phone call or email to your team.
