If you want to offer your users a hassle-free login experience, convenience and security, Single Sign-On (SSO) is the way to go. SSO is an authentication process that allows users to access multiple applications or services with a single set of login credentials.
Auth0 is an identity-as-a-service (IDaaS) platform that provides authentication and authorization services for applications and APIs. It offers a comprehensive set of features for implementing secure and customizable authentication solutions, including support for various authentication methods such as username/password, social logins, and multi-factor authentication (MFA).
In this article, you will learn more about SSO and Auth0 and how you can integrate it with your Drupal website.
Benefits of SSO Integration in Drupal
Seamless User Experience: Integrating SSO into Drupal enables users to log in once and access all connected applications seamlessly, eliminating the need for multiple logins and enhancing user convenience.
Centralized User Management: SSO centralizes user authentication and authorization, making it easier for administrators to manage user accounts, permissions, and access control policies across multiple Drupal sites or integrated applications.
Enhanced Security: SSO enhances security by enforcing consistent authentication policies and enabling centralized management of user access, reducing the risk of security breaches due to weak passwords or unauthorized access.
Reduced Development Efforts: By leveraging Auth0's SSO capabilities, developers can significantly reduce the time and effort required to implement authentication and authorization features in Drupal applications, accelerating the development process and time-to-market for new features and functionalities.
