What is a requirement for "Custom Authentication" in OutSystems?

Custom Authentication in OutSystems offers significant flexibility for developers when it comes to user authentication. By choosing to implement custom authentication, developers can create and integrate their own authentication mechanisms tailored to the specific security needs of their applications. This allows them to go beyond the default authentication methods provided by OutSystems, enabling them to meet unique business requirements or integrate with existing systems.

This option is particularly advantageous in scenarios where standard authentication protocols may not suffice, allowing developers to design and deploy systems that can connect to various identity providers, adapt to specific organizational workflows, or comply with particular security standards. Custom Authentication empowers developers to control the entire authentication process, ensuring that it aligns well with the business logic and user experience they aim to achieve in their mobile applications.

The other choices do not accurately capture the core essence of what Custom Authentication enables. The requirement for users to create their own authentication protocol is misleading, as OutSystems provides a framework for developers to implement their preferred methods without mandating them to establish a completely new protocol. Similarly, the notion that it cannot be used with external databases is inaccurate since custom authentication can interact with different data sources. Lastly, while it may utilize third-party services in some implementations, a third-party service is not a requisite for establishing custom authentication.
