What types of user authentication can be implemented in OutSystems?

The correct answer highlights the comprehensive range of user authentication methods available in OutSystems. Specifically, OutSystems supports multiple authentication procedures to cater to different user needs and preferences.

Email and password authentication is the most traditional and widely used method, allowing users to create accounts and log in with their credentials securely. In addition to this, social login options enable users to authenticate using their existing accounts from popular platforms like Google, Facebook, and others, streamlining the login process and enhancing user experience by reducing the need for new passwords. Moreover, Single Sign-On (SSO) facilitates authentication across multiple applications with one set of credentials, which is particularly beneficial for enterprises that want to simplify access to various services for their users.

This multifaceted approach to user authentication in OutSystems not only increases security but also improves user engagement by providing flexible login options, addressing various user preferences and organizational requirements in identity management.
