In .NET MAUI, I often see a few common ways to handle authentication/authorization. The most basic is to authenticate with an API token or JWT, using HttpClient to send a Bearer Token in the request. For applications that need more security, you can integrate OAuth 2.0 or OpenID Connect through services like Azure AD B2C. In addition, for internal apps, authentication with Secure Storage combined with role-based authorization is a compact and That’s Not My Neighbor effective solution. Depending on the specifics of the application, I choose to balance security and user experience.
